View Full Version : Recent earthquake activity and topographic map

Files taken from the USGS (http://earthquake.usgs.gov/recenteqsww/catalogs/). To display earthquakes, download one of the KML files (see links below) and open it in Google Earth. Earthquakes are colored by age (red = past hour, orange = past day, yellow = past week) and sized by magnitude.

Magnitude > 1, past 7 days (http://earthquake.usgs.gov/recenteqsww/catalogs/eqs7day-M1.kml)
Magnitude > 2.5, past 7 days (http://earthquake.usgs.gov/recenteqsww/catalogs/eqs7day-M2.5.kml)
I've added a topography map as image overlay (attachment) which more clearly shows the tectonic plates on GE, if somebody has a good map overlay identifying the various names of the plates that would be great (I couldnt find one). A good document explaining tectonic plates, earthquakes etc, can be found here (http://geology.usgs.gov/pdf/planet.pdf) (big download, 3.3 MB, pdf file).

Another exampe of the great stuff that can be done with GE.

Enjoy and stay away from the big quakes/tsunamis!

It seems that the latest download for the earthquake overlay is now a KMZ file.
I have Google Earth on my XP and Mac machines but running Keyhole 2 LT on a Windows 98 machine. Keyhole can't read the new KMZ file. Other than OS upgrade is there a workaround? It appears that the old earthquake KML files are no longer updating.

I was wrong. The older 7 day earthquake KMLs do still update in Keyhole 2LT. I know that this forum is for GE users but but it would be nice for Keyhole users (windows 98se) to know where they could get their hands on these files, if they are still available.
