Does the Pacific Northwest have an earthquake early warning system?
The U.S. Geological Survey, the University of Washington-based Pacific Northwest Seismic Network and the Washington Emergency Management Division on Tuesday, May 4, will activate the system that sends earthquake early warnings throughout Washington state.
Is there any warning before an earthquake?
Over the last few years, the U.S. has rolled out an earthquake early warning system for the West Coast called ShakeAlert. When an earthquake occurs, real time data from seismometers is used to determine how large an earthquake will be and which areas will be affected.
How much warning time could the ShakeAlert system provide?
10 seconds
The ShakeAlert system could provide people up to 10 seconds of lead time when an earthquake hits, said Robert de Groot with the USGS. De Groot is an earthquake scientist and communications coordinator for the ShakeAlert early warning system. The alert also warns users to potential aftershocks, de Groot said.
How do I get ShakeAlert in Seattle?
People in Washington will be able to receive ShakeAlert Messages directly on their phones through three pathways:
- The MyShake app.
- Wireless Emergency Alert (WEA) messages.

How do early warning systems work?
Detailed Description. Earthquake early warning systems like ShakeAlert® work because an alert can be transmitted almost instantaneously, whereas the shaking waves from the earthquake travel through the shallow layers of the Earth at speeds of one to a few kilometers per second (0.5 to 3 miles per second).
How do I get ShakeAlert on my Iphone?
Apple iPhones:
- Tap “Settings” > “Notifications”
- Scroll to the bottom of the screen.

How does the ShakeAlert system work?
Network approach: The network approach utilizes many seismic sensors distributed over a wide area where earthquakes are likely to occur. This network of sensors sends data to a central site where ground motion signals are analyzed, earthquakes are detected and warnings are issued.
When’s the next earthquake in Washington state?

What is Earthquake Early Warning (EEW)?
Earthquake early warning (EEW) detects and measures earthquakes fast enough that warning can be given before the strongest shaking arrives, providing seconds to minutes to prepare. Earthquake early warning is being implemented in many locations around the world.
What is ShakeAlert Washington State?
