The earthquake series off Tröllaskagi peninsula has calmed down somewhat since it peaked one week ago but every now and then, quakes stronger than 3.0 occur, ruv.is reports.
According to the Icelandic Met Office, continued seismic activity can be expected in the region. Seismologist Ragnar Stefánsson points out to Morgunblaðið that there is not much risk of tsunamis in Iceland.
“Our earthquakes are characterized by horizontal movements where the plates go crosswise along each other but where the biggest tsunamis occur, as in the Pacific, the plates move vertically,” Ragnar explains.
Dr. Sigurjón Jónsson, a geophysicist and associate professor at the King Abdullah University in Saudi Arabia, has monitored the developments.
He told ruv.is last week that it appears as if tension is building up in the Húsavík fault system. If it is discharged all at once it might lead to an earthquake of a 6.8 magnitude.
“The evaluation depends on certain conditions and is not above criticism. However, it is evident that tension is building up,” he reiterated.
According to Sigurjón, the activity began relocating to the east last week while also continuing in the western part of the fault system.
Last week search and rescue workers walked between homes in North Iceland to prepare inhabitants for a strong earthquake. Go to almannavarnir.is for further information.
