I'd forgotten about the USGS earthquake monitoring websites. Used to check them daily. Have gotten out of the habit while in Hawaii. If the last Japanese earthquake piqued your curiosity, consider looking here and here. Red lines are the fault zones. Colored squares are measurable earth movement. Mostly they are real earthquakes. Occasionally they are construction blasting. Geysers apparently generate measurable movement, too.
Give thanks for our ability to adapt to and co-exist with the geological and meterological events that occur frequently in our own back yards.
Pray for those in Japan and elsewhere who are now dealing with the effects of the 11 Mar Japanese quake.
