It is my understanding that gale warnings are quite common over there for sure.
There have been three more quakes there since I last posted a little bit ago.
Earthquake swarm in Langjökull Still seismicity southeast of Húsafell, or the southwest Langjökull. the tremor measured between 2 and 3 on the Richter scale last night, but four earthquakes in the concentration range have been detected in the last 48 hours. In addition, there have been less severe earthquakes. There are no obvious explanations for this swarm, which began before the weekend.
The Hengill volcanic system, cutting through Thingvallavatn lake, consists of a series of NE-SW-trending fissure vents, crater rows, and small shield volcanoes occupying a strongly faulted graben.
Hengill is the easternmost of a series of four closely spaced basaltic fissure systems that cut diagonally across the Reykjanes Peninsula and lies at the triple junction of the Reykjanes Peninsula volcanic zone, the Western volcanic zone, and the South Iceland seismic zone. Postglacial lava flows surface much of the volcanic system. The latest eruption was radiocarbon dated about 1900 years before present. An eruption in the Hellisheidi area once thought to have occurred around 1000 AD at the time of a meeting of the Icelandic parliament at Thingvellir is now known to have occurred at a vent about 5 km away in the Brennisteinsfjöll volcanic system. Geothermally heated greenhouses, hot springs, and geysers are found at the Hveragerdi thermal area.
