Strong Gulf of CA Earthquake

How strong? 6.9, which is a HUGE quake by any standard.


Click the image for details.

Don't forget to go to the Did You Feel It? webpage of the USGS!

This shows what people felt in terms of both Richter and Mercalli scales.

Have your students record some recent ones and then use a Mercalli Scale to record what types of things they could have noticed in their area. Record on a Map.

Teachable moment! Grab it!
