Reykjanes volcano (Reykjanes peninsula (SW Iceland)) activity update: Alert level raised to Yellow- earthquake swarm, inflation
Mon, 27 Jan 2020, 15:2415:24 PM | BY: MJFLEGEND
IMO reports: An inflation has been detected since January 21st and is centred just west of Mt. Thorbjorn on Reykjanes peninsula. The inflation is unusually rapid, around 3-4 mm per day and has accumulated to 2 cm to date. It has been detected both on continuous GPS stations and in InSAR images. The inflation is most likely a sign of magma accumulation at a depth of just a few km. If magma accumulation is causing the inflation, the accumulation is very small, with the first volume estimate is around 1 million cubic meters.

A state of uncertainty has been declared. The Aviation Colour Code has been raised to Yellow for Reykjanes.

A shallow (10 km) magnitude 4.8 earthquake with many pre- and aftershocks (or a seismic swarm) occurred this morning (Sun) at 07:34 UTC at the SW tip of the Reykjanes peninsula, on the SW active rift zone. The swarm of earthquakes included several quakes of magnitude 3 and higher. The strongest earthquake was widely felt in SE Iceland. read all

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. read all

A seismic swarm has occurred on the Reykjanes Ridge 70 km offshore the SW tip of Iceland. About 40 earthquakes with magnitudes mostly between 2 and 3 were recorded. The Reykjanes Ridge is part of the active SW rift zone running through the western part of Iceland. read all
