Activity at Katla

Over the weekend (29/8), two magnitude ~4.5 earthquakes were measured in the vicinity of Katla volcano in Iceland.   Back in July, the IMO issued a news article  regarding an increase in microseismicity in the area.  As the article mentions, such activity is common in the summer months due to melting water from the glaciers in the area.  Erik Klemetti’s blog on gives an excellent summary of what this latest activity might indicate.  It is worth noting that historically, earthquakes at Katla don’t always lead to an eruption but the IMO are keeping a close eye on the situation in case the situation changes.  You can keep up with the latest seismic activity at Katla on the IMO website here.
