Probably several more days of earthquakes to come

Kristín Jónsdóttir, natural disasters specialist with the Icelandic Met Office, says the earthquake swarm in southwest Iceland has produced more quakes since midnight than yesterday, including three over Magnitude 4 this morning that were clearly felt across the region. She predicts the seismic activity will continue for at least several more days.

Most of the quakes have been around Keilir mountain on the Reykjanes peninsula, but also close to Trölladryngja, and one at Reykjanestá.

Kristín says it is important for people to remain calm and listen to recommendations from the civil protection authorities. 

There is no indication of land rise or volcanic instability beneath the surface. 

Similar earthquakes swarms have affected the same region several times over the past century or so. 

“It is by far the most likely that this will carry on for the coming days and then this seismic activity will die down,” Kristín says. 

Over 1,500 measurable earthquakes have occurred since midnight. The largest was Magnitude 4.9 at 01.31 last night. 18 quakes larger than Magnitude 3 have occurred so far today. More than 11,500 earthquakes have been measured since Wednesday morning—200 of them over Magnitude 3. 

Whether the swarm dies out slowly or ends with a series of larger quakes as significant as Magnitude 6.5, with an epicentre further east than so far, remains to be seen. Damage to buildings is unlikely in both instances, however, according to civil protection chief Víðir Reynisson, who says the biggest danger is from falling items within homes and workplaces. Even relatively large items could move in a bigger quake and should be secured now, he says.
