This isn't directly volcano-related, but the USGS (and CNN) are reporting that a 7.0 earthquake just occurred in Haiti. Looking at the map, it seems that it epicentered only 10 miles/15 kilometers from Port Au Prince, the biggest city in Haiti. The earthquake was at 10 km depth - so a fairly shallow earthquake related to the complex transform faulting along the boundary of the Caribbean and Atlantic plates. A Tsunani Watch has been issued for the Caribbean as well - but the US Pacific Tsunami Warning Center believes that the only effects will be local (within 100 km) of Hispaniola.
