Analysis and quasistatic FE modeling of long period impulsive events associated with explosions at Stromboli volcano (Italy)
volcano seismology long-period measurements Stromboli finite element calculations volcano sources
2015/10/8
Broadband seismic measurements performed in 1995 and 1996 in the summit region of Stromboli are analyzed. The experiment in 1995 used an array of four Guralp seismometers and one Wielandt-Streckeisen ...
Tornillo seismic events at Galeras volcano, Colombia: a summary and new information from broadband three-component measurements

Long-duration events have been recorded at several active, andesitic volcanoes. Their main characteristics are a single, sharp frequency peak, and an exceptionally long coda. Because their seismograms...
A scheme for the preparation of strong induced seismic events
Induced seismicity rigid inclusion rockburst
2015/9/30
A scheme of rockburst preparation is proposed from an analysis of induced seismicity."Rigid" inclusion is the basis of this scheme. Intensive destruction of the inclusion begins when a critical flaw c...
