An M4.5 earthquake registered near Trölladyngja on the Reykjanes peninsula shook Southwest Iceland around 10:50 this morning.
A smaller, secondary M3.9 earthquake was registered soon after, at 10:54 local time. Smaller aftershocks were also registered.
According to the Meteorological Office of Iceland, the earthquakes originated at a depth of 5 km [3 mi]. The Meteorological Office further stated that they are likely “trigger” quakes, which accompany magma movement.
The quakes were felt throughout much of South and West Iceland. The epicentre was located at around 20 km [12 mi] north-northeast of the Svartsengi power plant, where recent land rise due to magma intrusion has been detected.
