Mt. Thorbjorn volcano (Reykjanes peninsula, Iceland): decreased seismic activity; possible re-inflation
Thu, 28 May 2020, 08:5708:57 AM | BY: MARTIN
The Icelandic Met Office (IMO) reported that the seismic activity has decreased on Reykjanes peninsula in recent weeks. During the past week (20-27 May) around 120 earthquakes were located there, fewer than in the previous week when they were just more than 200. The largest earthquake was recorded with magnitude M 2.1.

On 26 May a new data were acquired/processed, which include InSAR, GPS and radon measurements. These new observations indicate subtle sign of slow re-inflation in the vicinity of Þorbjörn. A longer time series of data is needed to better constrain the ongoing process and evaluate the associated hazards.

Reykjanes volcano (Iceland) - Smithsonian / USGS Weekly Volcanic Activity Report for 29 April-5 May 2020 (Continuing Activity)
IMO reported that uplift detected in the Thorbjorn area decreased in the beginning of April and stopped later in the month. Seismicity, which had occurred across three main volcanic systems: Eldey, Reykjanes-Svartsengi, and Krýsuvík, had significantly decreased. These data indicated that the injection of magma beneath Thorbjorn had stopped, though there were indications of deformation over a larger area. ... Read all
