Galeras volcano (Colombia): seismic swarm triggers eruption warning

The Colombian volcano monitoring institute INGEOMINAS has raised the alarm level for Galeras volcano, after a number of so-called tornillos, a characteristic seismic signal often preceding eruptions at Galeras, were detected in recent days. Tornillos consist of a screw-driver shaped signal of rapdily increasing and then slowly decreasing harmonic tremor and preceded most eruptions of Galeras between 1992 and 2010. ... Read all

INGEOMINAS reported that during 15-22 November steam from Galeras rose from the main crater, two craters to the N and SW (Paisita and Chavas, respectively), and a crack on the N flank of the active cone. Seismicity was at low levels, although some earthquakes were characterized as "tornillo-type." During 23-24 November the seismic network detected an emerging seismic pattern of "tornillo-type" earthquakes similar to patterns detected prior to past eruptions. Gas emissions also decreased. ...
