We monitored the displacement and seismic activity of an unstable vertical rock slice in a natural limestone cliff of the southeast Vercors massif, southeast France, during the months preceding its collapse. Displacement measurements showed an average acceleration ...

<p>While mining the approved stope sequence in the 100/900 ore bodies at the North Mine in Sudbury Basin of Vale Inco Ltd and following a crown blast in one of the stopes in 100 orebody in a sill pillar area, several major seismic events, with the highest ...

We analyse the statistical pattern of seismicity before a 1-2 10³m³ chalk cliff collapse on the Normandie ocean shore, Western France. We show that a power law acceleration of seismicity rate and energy in both 40 Hz-1.5 kHz and 2 Hz-10kHz ...
