Earthquakes are happening around the world all the time, we just can’t feel all of them. The US Geological Survey (USGS) is constantly monitoring the Earth with sensitive instruments and for some time now has offered ways of sharing their data on the web through their Earthquake Hazards Program. Last February I reported on their new Google Earth earthquake monitoring features. They have recently refined the interface and in addition to real-time seismic activity world-wide, they now show faultlines, tectonic plate boundaries, and convergence points for faults with colored lines on the Earth (there’s a key to the colors in the places folder). I’m travelling at the moment, so I don’t have a time to show a new screenshot, but check out the USGS Earthquake monitoring network link. This is a nice improvement to an already amazing tool to monitor geologic activity of the Earth. It is in my permanent places folder. Thanks to a GEB reader who I only know as “GE_fan” for letting me know about the update.
