This map is centered on our home/farm. There have been 98 earthquakes reported by the USGS since January 1, 2008 with an epicenter within 30 miles (48 km). (There have been more reported, but earthquakes centered on known gravel pits and indicating the movement is centered at the surface have been discarded as gravel pit blasting.)

The markers used to show epicenters are sized relative to the size of the earthquake. The stongest earthquake this year was a 2.6 magnitude quake that occurred February 4, 2008. The markers are:

magnitudes 1.0-1.4 magnitudes 2.0-2.4

magnitudes 1.5-1.9 magnitudes 2.5-2.9

Use the in the top left corner of the map to zoom in or out. The scroll wheel on your mouse (if you have one) also will zoom the map. Click and hold the map and slide your mouse to pan to another center point.

If your mouse hovers over a pushpin the date and magnitude of the quake will be displayed.

Oldest earthquakes are displayed first, so newer quake pegs may cover older quakes.

Purple rings indicate 10 mile (16km) distance from the farm.
