In case you haven’t heard a 5.9 earthquake hit Virginia just outside of Richmond. I felt it in Durham, NC and Kevin felt it out on the coast. Reports from Twitter indicate it was also felt up in Boston. If you felt it, you can log into the USGS website and report your local conditions. A . . . → Read More: Virginia Earthquake

Only one is defined, the Precambrian spanning from the formation of the Earth to right before life goes crazy in the Cambrian explosion (4.6 billion years ago to 542 million years ago). Oddly, there is no other supereon after the Precambrian, just the Phanerozoic eon . . . → Read More: On the Reasons Why We Need A New Supereon
