... should be an "active" year. The volcano Hekla has been erupting regularly over the last decades (every 10 years since 1970). Volcanologists have reported that the pressure in the magma chamber is near the pressure measured in previous eruptions. The Icelandic Meteorological Office also pointed at the presence of snow-free spot new the volcano's summit.
Hekla is not the only volcano expected to blow. The volcano Katla is also been monitored closely. Magma intrusions are measured by the uplifting of the terrain.
This is all accentuated by the sismic activity and recently it has been quite active. In the last 48 hours, 245 tremors and earthquakes were recorded on the Reykjanes ridge (out of the 320 for the entire country). 25 of them are over a magnitude of 3 on the Richter scale: 2 of them were over 4 (10 times stronger than 3 on the Richter scale). The map available on veður.is is like a really christmas tree...
