Hazard-Specific Alerts (Earthquake & Tsunami)

Hazard-Specific Alerts

Some hazards are unique and require unique ways to alert for them. Below are two that you may come across in Southern California:

Earthquake Early Warning

ShakeAlert®  is an earthquake early warning (EEW) system that detects significant earthquakes and can quickly send alerts that can reach people further from the epicenter before shaking begins. ShakeAlert is not earthquake prediction, but rather a ShakeAlert message indicates that an earthquake has begun and shaking is imminent.

The U.S. Geological Survey (USGS) along with a coalition of State and university partners are now implementing Phase 3 of operations of the ShakeAlert Earthquake Early Warning System for the West Coast of the United States. Many partnerships to utilize ShakeAlert in authentic environments such as utilities, hospitals, transportation systems, and educational environments are active today and more are being developed.

Tsunami Warning

Although not a coastal city, City of Riverside’s proximity to the beaches means residents should know how to receive and interpret Tsunami Warnings in case they go to enjoy a relaxing beach day. While some beaches have sirens that can be activated, not all do. If you go to the beach, ensure you know how to receive warnings, and know the plan for an evacuation. Most cities have evacuation routes posted online, and signs posted in key areas.
