Earthquake Triggers Slow Motion Quakes New Zealand
2017/9/20
Slow slip events, a type of slow motion earthquake that occurs over days to weeks, are thought to be capable of triggering larger, potentially damaging earthquakes. In a new study led by The Universit...

The history of Vesuvius and its central cone or Great Cone (Gran Cono) is important because it enables us to improve our understanding of the structural evolution of Somma-Vesuvius. Apart from geologi...
In 1995, we published the first release of the Catalogo dei Forti Terremoti in Italia, 461 a.C. - 1980, in Italian (Boschi et al., 1995). Two years later this was followed by a second release, again i...
