Whether this is a coincidence or not, I thought I'd mention a report of an earthquake near the crater of Nevado del Huila in Colombia. The earthquake is reported as a magnitude 4.6 and at a depth of 20 km (although that is only a rough estimate), indicating that magma might be moving up the conduit system under the volcano - or that it might be just coincidental seismicity in a seismically active area. However, Huila had recently become active for the first time in 500 years, so this could be a sign of new activity to come.
