Information about earthquakes by USGS in Google Earth

There has been an earthquake in California on May 17. Magnitude 4.7. It is understandable that in such circumstances people are searching for reliable, scientific sources regarding epicenters, magnitude, aftershocks etc. There are many sources giving such information. I would like to present on of them shortly.

Earthquake Information from the USGS

USGS provides detailed information concerning earthquakes. What I liked the most were Google Earth kmz Files:

M1+ Real-time Earthquakes, Past 7 Days

They display real-time information, updated every 5 minutes for California Events and 30 minutes for world-wide events. There are 2 kmz files available:

* Earthquakes colored by age
* Earthquakes colored by depth



You can choose what magnitude events you want to see, you can choose one particular event and see details or go from one event to other kmz maps such as: Historic earthquakes since 1970 (M 3+):


There is also a Shakemap available:
