Moderate earthquake which may be volcanic in origin.
UPDATE 21:04 UTC : What we expected has been proved right, Iceland Grimsvotn volcano which is located below the Vatnajokull glacier has started its eruption.
Approx. 50 km from the Vatnajo.... (you know).
Very close to Laki. Laki or Lakagígar (Craters of Laki) is a volcanic fissure situated in the south of Iceland, not far from the canyon of Eldgjá and the small village Kirkjubæjarklaustur, in South-East Iceland. Lakagígar is the correct name as the Laki mountain itself did not erupt, but fissures opened up on each side of it (source Wikipedia)

This earthquake list covers important earthquakes in the world.
If a more detailed page is present, the earthquake line will be linked to the detailed page.
For your comfort, we will provide in most cases Google Satellite Map links to give you an idea where the earthquake struck, which terrain it happened and if villages or cities are located in the immediate vicinity. The reference for the time zone is UTC (Coordinated Universal Time, also called GMT)
The page is regularly updated to add new earthquakes.
green color = NOT dangerous for damage or injuries
orange color = MODERATE risk for damage or injuries
red color = CONSIDERABLE risk for damage or injuries
