112:. In the seismic records, he found that so-called “B-type events” or “long-period events” had occurred with increasing frequency prior to the eruption.

Since 1977, Chouet’s colleague Keiiti Aki had been developing mathematical models of magma-filled fractures in volcanoes, in order to determine what seismic waves would be produced by such fractures. Since 1985 Chouet himself had also been developing models of such fractures. The turning point in
