A recent earthquake measuring 4.1 on the Richter scale rattled parts of the Los Angeles area, including Corona, Anaheim, and Santa Ana. Despite the high population density of the region, there was minimal damage reported. The quake occurred near the Elsinore fault and triggered the ShakeAlert Earthquake Early Warning System, estimating the magnitude to be as high as 4.5 initially.
The ShakeAlert system provides alerts to individuals within a certain range of the epicenter, giving them only a few seconds warning before the shaking begins. Those closer to the epicenter may not receive alerts until after they feel the shaking, known as the late alert zone. The Wireless Emergency Alert (WEA) system is only activated for earthquakes measuring 5 or higher.
It is important to report any earthquake activity to the USGS and remember to drop, cover, and hold on if shaking is felt. The science behind predicting and reacting to earthquakes is essential in order to ensure public safety and preparedness.
