And now for something completely different - volcanic eruptions. In February
2000, Mt. Hekla erupted in a small eruption.
Although the network was incomplete at the time a significant coeruptive
signal was observed of 7 mm towards the volcano, resulting from
deflation of the magma chamber. The offsets fit quite well to
predicted displacements from a model based on borehole strain data.
