Iceland: Earthquake M 5.6

On the Icelandic Reykjanes Peninsula, the earthquake struck this afternoon at 13.43 UCT with a magnitude of 5.6, with the epicenter located 3.9 km west of Krýsuvík and only a few kilometers from Grindavik. The hypocenter was located at a depth of 3.3 km. The quake could be felt in large parts of southwest Iceland and shook the capital. For Iceland it was a strong quake. There were numerous aftershocks, although I would honestly say that the main quake triggered a seismic swarm. So far 219 quakes have been registered, 12 with magnitudes greater than 3.

Alaska: Earthquake Mw 7,5

Off the coast of the US state of Alaska, the earth shook last night with a magnitude of 7.5, the epicenter being located 84 km southeast of Sand Point. This is a place on the Aleutian island of Unalaska. The hypocenter was at a depth of 40 km. Despite the relatively large depth of the earthquake epicenter there was a tsunami alarm. The same applies to larger damages. The region is only sparsely populated. In relative proximity to the location of the earthquake are some volcanoes that are classified as potentially active: Mount Makushin, Mount Okmok and the volcanic island of Bogoslof, to name only 3. The volcanism of the region is directly related to the Aleutian subduction zone where the earthquake occurred.

As is typical for earthquakes of this magnitude, there were numerous aftershocks. The strongest one had the magnitude 5.9 and further aftershocks must be expected.

La Palma: Seismic swarm

The Canary Island La Palma was again hit by a swarm quake yesterday morning. The seismographs recorded 25 tremors with magnitudes between 1.6 and 2.0. The hypocenters were at depths between 20 and 45 km. In this area of the asthenosphere, it is usually ascending magma that triggers light tremors. The epicenters were located in the south of the island, which was formed by eruptions.

In addition, seismicity is also increased in other regions of the Canary Islands. For example, it shook unusually often in the area of Tenerife and El Hierro is also still affected by sporadic quakes. Although there are no indications of an imminent volcanic eruption, in the longer term an eruption could occur again. In my opinion the most promising candidate is La Palma.

Bardarbunga: Earthquake M 4.8

Under the Icelandic glacier volcano Bardarbunga one of the strongest earthquakes of the last months occurred. It had a magnitude of 4.9 and its epicenter was 8.3 km east of the caldera. The epicenter of the earthquake was located at a depth of 4.8 km. A total of 12 earthquakes were recorded in the area of Vatanjökull within 48 hours.
