Did you feel the 4.2 Earthquake that rattled Southern California last week?
A 4.2-magnitude earthquake struck the Pacoima area of the San Fernando Valley early Thursday morning of July 30th. It was felt across the Southland with many news stations shaking live on the air. The area shuddered with aftershocks following the quake about five miles deep but, there were no immediate reports of damage. Initially, there was a small chance that a larger earthquake could occur, but that likelihood decreased over time, the Southern California Seismic Network said.
It was the largest earthquake in the area since a 4.4-magnitude one struck in March 2014. Earthquakes of that scale are known to shake items off shelves and cause cracks in plaster or windows, depending on the condition of a structure. Therefore, structural strengthening of older buildings or performing seismic retrofits for buildings not up to Life Safety standards is crucial. The geological survey forecasts a 31 percent probability of a 7.5-magnitude quake occurring in the Los Angeles area in the next 30 years. This is a good reminder to be sure your prepared and confirm buildings are retrofitted for Life Safety and reducing the PML (SEL or SUL) to below 20.
Seismic retrofitting of vulnerable structures reduces risk and liability. It is important for protecting the lives and assets of building occupants as well as the continuity of their work. If you live or work in retrofitted structures, you’re less likely to be injured during an earthquake.
