Yesterday, there was a lot of earthquake activity on Iceland. At noon, a swarm with about 50 quakes partly preceded and followed a magnitude 4.2 quake at 5.8 km depth beneath the Reykjanes peninsula, near the axis of the the SW volcanic rift zone. Most quakes were between magnitudes 1-2 and at around 5 km depth. ... [mehr]

Ein seismischer Schwarm aufgetreten auf der Reykjanes Ridge 70 km vor der Küste die SW-Spitze von Island. Rund 40 Erdbeben mit Magnituden meist zwischen 2 und 3 wurden aufgezeichnet. Die Reykjanes Ridge ist Teil der aktiven SW Rift Zone ausgeführt durch den westlichen Teil von Island. ... [mehr]
Reykjanes VulkanReykjanes volcano in SW Iceland is located where the Mid Atlantic Ridge emerges onto land. It forms a vast area with many eruptive fissures, lava fields, hot springs and mud pools. In 2000, a large earthquake lowered the water level in Lake Kleifarvatn by 5 metres, but has gradually returned to normal since then.
Beschreibung:The Reykjanes volcanic system at the SW tip of the Reykjanes Peninsula, where the Mid Atlantic Ridge rises above sea level, comprises a broad area of postglacial basaltic crater rows and small shield volcanoes.
The Reykjanes volcanic system is the westernmost of a series of four closely-spaced fissure systems that extend diagonally across the Reykjanes Peninsula. Most of the volcanic system is covered by Holocene lavas and eruptions have occurred in historical time during the 13th century at several locations on the NE-SW-trending fissure system.
