Tens of thousands of tremors have been recorded by the Icelandic Met Office (IMO) in recent weeks, including more than a thousand during a 24-hour period this week, signalling an uptick in volcanic activity.
In an update issued shortly after midday on Thursday (9 November), the IMO said it had detected seven earthquakes of at least magnitude 4, including one of magnitude 4.8 – the largest since the activity began in late October.
It added magma accumulation was ongoing, and that "an acceleration of the process had been observed between days" bringing with it "episodic seismic activity".
