The Next Big Earthquake Estimated to Displace Up to 400,000 Californians

earthquake retrofitting

We know the “Big One” is coming for California.

While it’s important to take all of the necessary steps to protect your loved ones and your home from earthquake damage, sometimes even the most prepared residents will face losses.

In fact, it’s estimated that 250,000 – 400,000 people could be displaced from their homes or apartment buildings if a massive earthquake erupted along one of California’s active faults.

In San Francisco, seismologists predict 400,000 people could lose their homes if a 7 magnitude earthquake or higher erupted on the Hayward fault line. The active fault runs through major bay cities like Berkeley, Oakland and Fremont.

While in Southern California, some 250,000 people could be left homeless if a massive earthquake occurred on the San Andreas fault.

Though many people will seek refuge from friends, families and shelters, residents in the Bay Area may have to completely evacuate their comminutes due to damage from all of the buildings that have not been retrofitted up to code.

And if you’re thinking about fleeing California all together after a major earthquake, you may want to think again. Down power lines and damaged highways will make travel extremely difficult, leaving many residents with limited options.

Luckily, seismologists predict areas like Orange, San Diego and Ventura will still be habitable after a 7.8 earthquake on the San Andreas fault.

While some earthquake damage can’t be avoided, experts are urging Californians to take all of the necessary steps to protect themselves and their homes in the event of a major temblor, because that’s the best place to seek shelter after a major disaster.

Home and building owners can prevent extensive earthquake damage by retrofitting older houses and apartments that are at a higher risk of collapse during an earthquake.

In addition to having your property retrofitted and brought up to current building and safety codes, you’ll want to store enough food, water, medicine and other supplies to last each person and animal in your home for at least three days.

Now more than ever it’s important to be proactive about earthquake preparation and safety.

San Andreas Fault Produces 4.5 Magnitude Earthquake, Felt Throughout Southern California

riverside earthquake

Residents near Riverside County were violently awakened by a 4.5 magnitude earthquake early Tuesday morning.

Occurring at 4:49 a.m., the temblor hit the Cabazon area with the epicenter near the Morongo Indian Reservation.

The quake occurred on a section of the San Andreas fault line that is known for producing smaller earthquakes.

“Seismologists call this region the ‘San Gorgonio knot’ because so many small faults intersect here and the main San Andreas trace is not clearly defined,” seismologist Lucy Jones posted on Facebook about the early-morning shaker.

Nearly 10,000 residents from San Diego to Los Angeles reported feeling the earthquake. Luckily no damage has been reported by Riverside County or Los Angeles County.

Residents described the earthquake as sounding like a “loud train rolling through the area.”

A magnitude 3.2 aftershock was reported around 4:51 a.m., along with several other smaller quakes occurring much deeper below ground.

This is the second time in just over a month that the Southern California region has been affected by an earthquake. In April, a 5.3 magnitude quake just off of the Channel Islands rattled So.Cal residents.

Now more than ever it’s important to be proactive about earthquake preparation and safety.

West Hollywood Makes Moves to Retrofit 800 Buildings at Risk of Collapse

west hollywood retrofits

West Hollywood is ready to get serious about earthquake safety.

According to a new city retrofit list, there are more than 800 buildings that are at risk of collapse or significant damage if a large earthquake were to occur.

Of the 800 buildings surveyed, 80% of the structures identified are wood-frame, such as apartment buildings with open carports located on the ground floor. The other 20% of the structures examined are said to be constructed of steel and concrete.

West Hollywood joins the likes of Santa Monica and Los Angeles in taking significant steps to prepare their communities for the imminent “Big One.”

In WeHo, the Hollywood fault line runs through the famous Sunset Strip and some of the buildings on the list include historical landmarks like Andaz West Hollywood, Mondrian, Standard and Sunset Tower.

City officials are hoping new retrofits will help keep residents safe during a disaster and preserve the city’s affordable and rent-controlled housing.

Since the area became its own city in 1984, West Hollywood has prided itself on providing affordable housing for their dwellers – almost 78% of the city’s residents live in rent-controlled housing.

“One good shaker without seismic reinforcements could bring many of those buildings into being red-tagged and having to be demolished — thus wiping out a good portion of our affordable housing stock,” Mayor Pro Tempore John Duran said (via the L.A. Times). “To me, this is about infrastructure repair and maintenance.

“We could see a massive overturn of many of our longtime residents if our buildings are not retrofitted,” Duran added.

Owners of the 800 buildings identified will receive a letter from the city notifying them of the building’s retrofit needs and will have a certain amount of time to comply or dispute the structure’s listing (if they can prove it has already been retrofitted).

The city’s estimated 738 soft-story wood-frame buildings are especially dangerous because the weak ground floors have been known to buckle during an earthquake. After the Northridge earthquake of 1994, 16 people who lived on the ground story of a similar soft-story structure died because of an apartment building collapse.

The city estimates it will cost between $40,000 and $160,000 to retrofit these wood-frame structures and $50 to $100 per square foot for retrofits costs of steel or concrete structures.

If you own a wood-frame, otherwise known as a soft-structure building, contact Julian Construction and we’ll conduct a free inspection for you. Taking action now will save countless lives and thousands of dollars.

Now more than ever it’s important to be proactive about earthquake preparation and safety.

New Study Finds Hayward Fault More Dangerous Than San Andreas

hayward fault

Earthquake country just got a little scarier.

According to a new study, the Hayward fault line that runs under Oakland, California is believed to be more dangerous than the infamous San Andreas fault line that spans Southern California.

The U.S. Geological Survey estimates that a quake of a magnitude 7 or higher could kill 800+ people and injure 18,000 more.

In fact, researchers are calling the 52-mile fault that’s centered under Oakland a “tectonic time bomb.”

“This fault is what we sort of call a tectonic time bomb,” USGS earthquake geologist emeritus David Schwartz told the L.A. Times. “It’s just waiting to go off.”

If the fault were to produce a sizeable earthquake, it’s estimated that the damage could cause 400 fires that could burn 52,000 homes in the area.

Unlike other active faults, the Hayward fault line runes under some of the most densely populated cities in the Bay.

There are 7 million people who live in the region and 2 million people who currently live directly on top of the fault.

Luckily, facilities near the Hayward fault line have started to take action. The old city halls have been abandoned and the Memorial Stadium at UC Berkeley has been refitted to avoid using areas that sit directly on the fault.

The scariest part of the Hayward fault is that California’s building and safety codes are no match for a sizeable quake. Currently, California requires buildings to adhere to minimum safety codes – meaning the structures need to be strong enough to allow people enough time to safely evacuate.

Assuming that every building in the region follows modern-day building and safety codes, that would still leave 8,000 structures collapsed and 100,000 structures red-tagged after a 7 magnitude or greater earthquake along the Hayward fault.

The Hayward fault has produced a major earthquake every 150-160 years, and on Oct 21st it will be 150 years since the fault’s last major quake.

Now more than ever it’s important to be proactive about earthquake preparation and safety.

California toma medidas importantes para la seguridad sísmica después de terremotos en México

earthquake retrofittingCalifornia toma medidas importantes para la seguridad sísmica después de terremotos en México

Los terremotos devastadores del año pasado en México han llevado a las ciudades de todo California a tomar medidas reales para la seguridad sísmica.

Por primera vez, en casi una generación, las ciudades del sur de California comenzaron a identificar edificios sísmicamente vulnerables en cada área.

“Lo que sucedió el año pasado en Ciudad de México, no queremos experimentar en California”, dijo David L. Khorram, superintendente de edificios y seguridad de Long Beach a L.A. Times, refiriéndose al terremoto masivo que dejó a 360 personas muertas.

Como resultado, Long Beach está en conversaciones para asignar $ 1 millón a la seguridad sísmica en un esfuerzo por identificar 5,000 edificios en el área que necesitan modificaciones de terremotos.

Malibu también está evaluando sus estructuras de historias blandas, mientras que áreas como Ventura y Hermosa Beach han seguido su ejemplo.

La retroalimentación promedio de pisos blandos de un edificio de apartamentos con estructura de madera va de $ 40,000 a $ 160,000 para reforzar. Los edificios de acero y hormigón cuestan un poco más, de $ 50 a $ 100 por pie cuadrado para actualizaciones sísmicas.

“Si nos fijamos en el costo de la retroadaptación en comparación con el valor del edificio, las matemáticas son realmente fáciles. Tenemos inversiones importantes en estas propiedades, y tenemos la intención de protegerlas “, dijo el director general de Real Estate Group, Michael Cusumano.

L.A. ha tomado medidas proactivas para remediar edificios vulnerables en el área. En 2015, la ciudad identificó aproximadamente 15,000 apartamentos y edificios de concreto que requieren modificaciones sísmicas.

Si tiene alguna inquietud acerca de la base de su hogar, comuníquese con Julian Construction para programar una inspección gratuita. Los problemas de la Fundación, que no se controlan, solo se volverán más dañinos y costosos con el tiempo.

California Takes Major Steps to Seismic Safety After Mexico Earthquakes

earthquake retrofitting

Last year’s devastating earthquakes in Mexico have prompted cities across California to take real action for seismic safety.

For the first time – in nearly a generation – cities across Southern California have started to identify seismically vulnerable buildings in each area.

“What happened last year in Mexico City, we don’t want to experience in California,” David Khorram, Long Beach’s superintendent of building and safety told the L.A. Times, referring to the massive temblor that left 360 people dead.

As a result, Long Beach is in current discussions to allocate $1 million to seismic safety in an effort to identify 5,000 buildings in the area needing earthquake retrofits.

Malibu is likewise evaluating their soft-story structures, while areas like Ventura and Hermosa Beach have followed suit.

The average soft-story retrofit of a wood-frame apartment building runs from $40,000 to $160,000 to reinforce. Steel and concrete buildings cost a bit more, at $50 to $100 per square foot for seismic upgrades.

“If you look at the cost of the retrofit versus the value of the building, the mathematics are really easy. We have significant investments in these properties, and we intend to protect them,” said the managing director of Real Estate Group, Michael Cusumano.

L.A. has taken proactive measures to remedy vulnerable buildings in the area. In 2015, the city identified roughly 15,000 apartment and concrete buildings needing seismic retrofits.

¿Estás viviendo en una zona de peligro sísmico? Nuevo mapa muestra lugares en riesgo

california earthquake fault zonesGracias a un nuevo mapa interactivo, es más fácil ver si estás viviendo en una zona de falla del terremoto de California.

The Geological Survey compartió un mapa interactivo en línea esta semana, que le permite ver si vive en una zona más propensa a sufrir daños por terremoto escribiendo su dirección o compartiendo su ubicación.

Además de mapear áreas cerca de las zonas de falla sísmica, el mapa fácil de usar también le dirá si su hogar se encuentra en una zona más propensa a la licuefacción o al deslizamiento de tierra también.

Las tres zonas diferentes delineadas por el mapa, todas tienen un riesgo importante en común: los edificios en estas zonas corren más riesgo de que el suelo se rompa (no solo se sacuda) durante un gran terremoto.

Si bien estos mapas han existido por bastante tiempo, nunca han sido fáciles de usar. Las publicaciones anteriores se realizaron en periódicos o archivos PDF, pero gracias a este mapa interactivo intuitivo, puede averiguar si su hogar está en riesgo en cuestión de segundos.

Esto es especialmente importante para los propietarios de viviendas y los propietarios de edificios comerciales por igual. “Cuando el suelo se rompe debajo de un edificio existente, hay una mayor probabilidad de que el edificio se derrumbe”, dijo Tim McCrink, geólogo de ingeniería supervisor del California Geological Survey, a L.A. Times.

Hay algunos factores diferentes que pueden conducir a la irrupción durante un terremoto. Primero, si la falla se rompe, un edificio que se extiende a ambos lados de la falla se puede dividir por la mitad. En segundo lugar, la licuefacción puede ocurrir cuando el temblor de un terremoto hace que la tierra falle y actúe como arena suelta o suelo saturado con agua subterránea. Como resultado, cualquier estructura que se asienta sobre este tipo de suelo se deslizará y eventualmente se empujará hacia abajo. Y tercero, un deslizamiento de tierra puede afectar una estructura que se ha construido con materiales débiles u obsoletos, que se encuentra en una ladera. Como resultado, estos edificios pueden colapsar con sacudidas extremas.

Si posee propiedades en una de estas tres zonas de terremotos, es importante que tome todas las medidas necesarias para reforzar su estructura. Las empresas, como Julian Construction, se especializan en reparación de cimientos y reacondicionamiento de terremotos.

Si está buscando comprar una propiedad nueva, es importante ver qué áreas tienen el mayor riesgo de rupturas por fallas, licuefacción o deslizamientos de tierra.

“El conocimiento es poder”, agregó McCrink. “Antes de comprar su propiedad, antes de construir … haga una investigación para ver cuáles son sus peligros”.

Are You Living in an Earthquake Hazard Zone? New Map Shows Places At Risk

california earthquake fault zones

Thanks to a new interactive map, it’s easier to see if you’re living in a California earthquake fault zone.

The Geological Survey shared an interactive map online this week, that allows you to see if you’re living in a zone more prone to earthquake damage by typing in your address or sharing your location.

In addition to mapping areas near earthquake fault zones, the easy-to-use map will also tell you if your home is in an area more prone to liquefaction or landslide as well.

The three different zones outlined by the map, all have one major hazard in common: Buildings in these zones are more at risk for the ground to break (not just shake) during a large earthquake.

While these maps have been around for quite some time, they have never been user-friendly. Previous publishing’s were done in newspapers or PDFs, but thanks to this intuitive interactive map, you can find out if your home is at risk in a matter of seconds.

This is especially important for homeowners and commercial building owners alike. “When the ground breaks under an existing building, there’s a higher chance that the building will collapse,” Tim McCrink, supervising engineering geologist for the California Geological Survey told the L.A. Times.

There are a few different factors that can lead to the ground breaking during an earthquake. First, if the fault ruptures, a building that straddles the fault line can be split in half. Second, liquefaction can occur when the shaking from an earthquake causes the ground to fail and act as loose sand or soil saturated with groundwater. As a result, any structure that sits atop this type of ground will slide and eventually be pushed down. And third, a landslide can affect a structure that has been built using weak or outdated materials, that sits on a hillside. As a result, these buildings may collapse with extreme shaking.

If you own property in one of these three earthquake zones, it’s important that you take all the necessary steps to reinforce your structure. Companies, like Julian Construction, specialize in foundation repair and earthquake retrofitting.

If you’re looking to purchase new property, it’s important to see which areas have the highest risk for fault ruptures, liquefaction or landslides.

“Knowledge is power,” added McCrink. “Before you buy your property, before you build … do an investigation to see what your hazards are.”

El sistema de alerta temprana de terremotos hace avances financieros

early earthquake warning systemEl jueves, los legisladores propusieron $ 22.9 millones para el sistema de alerta temprana de terremotos, que actualmente se encuentra en construcción en la costa oeste. El nuevo presupuesto propuesto duplica el presupuesto del año pasado de $ 10.2 millones.

“Los importantes fondos provistos en el proyecto de ley ayudarán a asegurar que la costa oeste tenga un sistema de alerta temprana de terremoto en funcionamiento en el futuro cercano”, dijo el representante Ken Calvert, presidente de un subcomité de la Cámara en un comunicado.

“Continuaré siendo un campeón de esta tecnología para salvar vidas que puede tener un impacto significativo cuando ocurren grandes terremotos. Tomemos los pasos que podamos para salvar a los estadounidenses de lesiones prevenibles durante desastres naturales “, agregó Calvert.
El nuevo presupuesto propuesto cubrirá $ 10 millones para la construcción real del sistema y $ 12.9 millones para el desarrollo continuo del mismo.

Por ahora, el proyecto de ley del sistema de alerta temprana de terremotos del Servicio Geológico de Estados Unidos se trasladará al Senado para otro voto.

“Este sistema no solo ayudará a proteger la infraestructura y las empresas, sino que también evitará lesiones y salvará vidas en California, Oregón y Washington”, dijo el representante de Burbank, Adam Schiff, en un comunicado.

Quienes viven en California saben que es un país sísmico, por lo que estas estaciones sísmicas son tan importantes para la detección de actividad sísmica como para salvar vidas y prevenir daños.

En San Francisco, un prototipo del sistema de advertencia temprana de terremotos proporcionó una advertencia de 8 segundos antes del temblor de magnitud 6,0 ​​en Napa.

Si bien la victoria presupuestaria en la casa es un avance, todavía hay un camino por recorrer. Se estima que el sistema completo costará $ 39.2 millones para construir a lo largo de la costa oeste y $ 16.1 millones para mantener.

Una vez completado, el USGS espera instalar notificaciones en hospitales, estaciones de bomberos, escuelas, centros comerciales y otras áreas densamente pobladas.
El temblor de un terremoto viaja a la velocidad del sonido a través de la roca, que es más lento que la velocidad de los sistemas de comunicación actuales, haciendo que sea completamente factible notificar al público con tiempo suficiente para salir de estructuras inseguras, detener trenes y detener cirugías.

Si bien el sistema aún está en construcción, es importante que si vives en California estás tomando las medidas necesarias para protegerte a ti y a tu hogar contra el daño causado por un terremoto.

Si tiene alguna inquietud acerca de la base de su hogar, comuníquese con Julian Construction para programar una inspección gratuita. Los problemas de la Fundación, que no se controlan, solo se volverán más dañinos y costosos con el tiempo.

Early Earthquake Warning System Makes Financial Headway

early earthquake warning system

On Thursday, lawmakers proposed $22.9 million for the early earthquake warning system, which is currently under construction on the West Coast. The new proposed budget doubles last year’s budget of $10.2 million.

“The significant funding provided in the bill will help ensure that the West Coast has a functioning earthquake early warning system in the near future,” Rep. Ken Calvert, chairman of a House subcommittee said in a statement.

“I will continue to be a champion for this life-saving technology that can have a significant impact when big earthquakes strike. Let’s take the steps we can to save Americans from preventable injuries during natural disasters,” Calvert added.

The newly proposed budget will cover $10 million for the actual construction of the system and $12.9 million for continual development of it.

For now, the U.S. Geological Survey’s early earthquake warning system bill will move to the senate for another vote.

“This system will not only help protect infrastructure and businesses, but also prevent injuries and save lives across California, Oregon and Washington,” Burbank Rep. Adam Schiff said in a statement.

Those who live in California know it’s earthquake country, which is why these seismic stations are so important for the detection of earthquake activity to save lives and prevent damage.

In San Francisco, a prototype of the early earthquake warning system provided an 8-second warning before the shaking of a 6.0 magnitude earthquake in Napa.

While the budget victory in the house shows progress, there is still a ways to go. It’s estimated that the complete system will cost $39.2 million to build along the West Coast and $16.1 million to maintain.

Once completed, the USGS is hoping to install notifications in hospitals, fire stations, schools, malls and other heavily populated areas.

The shaking of an earthquake travels at the speed of sound through rock, which is slower than the speed of today’s communication systems – making it completely feasible to notify the public with enough time to exit unsafe structures, stop trains and halt surgeries.

While the system is still under construction, it’s important that if you live in California you are taking the necessary proactive steps to protect yourself and your home from earthquake damage.
