Assessing Los Angeles Earthquake Risk
Los Angeles, situated in the seismically active region of Southern California, is at risk of powerful earthquakes. The Southern San Andreas fault, which runs through Los Angeles County, can cause earthquakes as big as magnitude 8.0. According to the United States Geological Survey (USGS), there is a 75% probability of one or more magnitude 7.0 or greater earthquakes striking Southern California within a 30-year period starting from 2014.
Recent Earthquakes in Los Angeles
Los Angeles experiences frequent earthquakes, with many being mild or moderate. In the past 24 hours, there has been one earthquake of magnitude 1.5 or greater. Over the past week, there have been seven earthquakes, and 33 earthquakes in the past 30 days. These recent earthquakes highlight the ongoing seismic activity in the region.
Effects & Damage of a Major Los Angeles Earthquake
A major earthquake in Los Angeles can have devastating consequences. The USGS estimates that a magnitude 7.5 or greater earthquake could cause:
- 1,800 deaths
- 1,600 fires
- 750 people trapped inside buildings
- 50,000 ER visits
- 19 days of search and rescue efforts
Mitigating Earthquake Damage in LA
To prepare for earthquakes, residents can take steps to mitigate damage. This includes:
- Securing heavy furniture and objects
- Storing heavy objects on low shelves
- Hanging heavy objects away from beds and couches
- Bracing overhead light fixtures
- Removing heavy objects from walls and shelves
- Storing flammable liquids in well-ventilated areas
- Keeping emergency supplies and a first aid kit handy
Los Angeles Earthquake Prediction
While predicting the exact time and location of an earthquake is impossible, understanding the seismic activity and fault lines in the region can help residents prepare. The San Andreas fault, which runs through Los Angeles County, is the longest fault in California and can cause powerful earthquakes.
