Is Grímsvötn volcano preparing to erupt?

In its annual spring field work, the research team from the Icelandic Meteorological Office measured a significant increase in volcanic gasses. The water surface of the subglacial lake within the volcano’s caldera is also high and a jokulhlaup is expected within weeks/months. The jokulhlaups often trigger an eruption, so the volcano is under high surveillance. The last eruption from Grímsvötn occurred in 2011 and emitted about 0.8 km3 of tephra.

The conditions can be quite challenging.
