Plate Boundaries and Central Va.

Plotting quakes for the last two days would easily identify the boundaries that the Earth's lithosphere is broken into and identify places that are regular visitors to the quake list. And, then there's central Virginia; far both in time and space from a plate boundary but shaking again. Three quakes yesterday: two @ 2.5 and one @ 2.0 shake us back to our new reality; we live in an earthquake zone.
The Pacific rim, the mid-ocean ridges shift and shimmy on: Japan, Indonesia, Kamchatka, Philippines, Chile, Central America, the Aleutians, Hispaniola, and the most active of all, the Scotia plate, are all on the list, as usual, but Virginia, to our dismay, is back on the list, as well.
Hang on Earthlings!!!

Central Va. Rockin' Again

After nearly a two week xmas/new year break the aftershocks return to the central Va. equake zone. A good rumble and rattle a little after 1 Saturday am (still not on the list), a 1.9 shake about 9:30 Sunday morning and another this morning at 8:09.  The rest of the planet shakes on as well, a 6.6 quake in the Santa Cruz Islands a couple of days ago is the only red on the list but the usual plate boundary locations shimmy on.
Hang on Earthlings!!
