About article:
The eruption on 27 March 1998 at the NE Crater, from 21h22 to 23h59 GMT, with Strombolian explosions and lava fountains, was the first of a long series of eruptive manifestations with relatively high energy, which affected the volcano after the 1991–1993 lateral event. The seismic activity occurred late in 1997 and the first months of 1998 constitutes, in the authors’ opinion, a precursor of this eruption and the successive eruptive events at the SE Crater, since it is believed to be associated with a conspicuous magma uprise. The continuous epicentre migration, in a brief time span, in various sectors of the volcano owing to the dynamics of different tectonic trends, is considered related to a rapid fluctuation in the local stress field, probably responsible for the sudden onset and rapid end of the eruptive event.
