Starting at 11:18, seismic tremor was observed at 1 and 1.5 Hz. This is consistent with lava/ice
interaction...
We are currently interpreting the depth of the majority of earthquakes(5-10 km) as the depth of the base of the dyke. The dyke has propagated about 5 km to the north since yesterday.
A model to fit the GPS data suggests that the volume of magma contained within the dyke is approximately 250 million
cubic meters.
It could be 0-20 hours before lava reaches
the surface of the ice. It is also possible that the lava will not break through the ice, and the
eruption could remain subglacial.
