Changes and Updates

January 17, 2006: Fixed IE 6 Javacript error.

November 12, 2007: Updated scripts for new data format from USGS, fixed centering bug (clicking a lat/lon now centers the map on that point)

To Do List

• Add sorting so earthquakes can be sorted by magnitude. Default is currently by time
• Update marker icons so they are color coded by earthquake magnituge - Done, mostly. Red marker is too big, need to make it smaller.
• Add magnitude to listing
• Create archive for earthquakes in Sonoma County. Currently the USGS only makes the last seven days available, so data is lost.
