As we informed in our latest update, the frequency of earthquakes have reduced, all below M 2.0. Scientists from the Icelandic Met Office (IMO) indicate that ongoing severe weather conditions over the peninsula might affect seismic instrument’s sensitivity, monitoring the smallest quake and making it more difficult to evaluate whether the seismic activity is really decreasing.
The effectiveness of investigations depends on the high sensitivity of earthquakes in real-time measurements.
Given the weather forecast for the upcoming two days, suggesting rainfall and strong wind, real-time GPS monitoring will be affected.
The latest satellite-based measurements show significant uplift of the ground in the vicinity of Svartsengi, due to the underlying magma intrusion.
The IMO continues: „The Icelandic Meteorological Office has increased surveillance in and around Grindavík and the area around Hagafell, while residents approach their properties and contractors work on protective measures.“
