A relatively high level of seismic activity was picked up around Krýsuvík, a geothermal area in southwest Iceland, yesterday evening. The series of minor earthquakes carried on into the night. The tremors peaked around midnight when one earthquake hit after another.

However, most of these earthquakes were small: around magnitude one on the Richter scale. The most powerful of last night’s earthquakes measured 2.3 on the Richter scale, ruv.is reports.
Seismic activity has regularly been picked up in Krýsuvík and surrounding areas in recent months where tremors like these are rather common. An earthquake of the magnitude 3.4 on the Richter scale hit near the town of Grindavík in mid-August.
