2.6 M Alabama Earthquake
From our friend Steve Jones:
A small magnitude 2.6 earthquake was registered earlier today at 15:20:10 UTC (9:20:10 am CST) in Alabama, at a location northwest of Birmingham, approximately 129 km (80 mi) from Huntsville. The quake focus was located at a depth of 1 km (0.6 mi) underground. There were no immediate reports of damages in the local area.
In Huntsville, the initial P (pressure) seismic body waves began to arrive some 12 seconds after the quake occurred, and the initial S (shear) body waves were seen at approximately +37 seconds. A phase of surface waves was seen to arrive beginning about 46 seconds after the quake, peaking at +51 seconds with a maximum vertical ground movement of approximately 144 micrometers (um) measured at the AlabamaQuake seismic station.
