The purpose of this pilot study was to develop a methodology to assess risk to life from cliff collapse. The report considers cliff collapse triggered by earthquakes and other causes, and expresses risk as annual individual fatality risk. The risk to life, ...

The objective in this experimental programme was to monitor microseismic activity at field scale in the same way that acoustic emission (AE) are monitored at sample scale, noting that the temporal variation of the AE level (or cumulated level) appears to be ...

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>The Strood and Higham Railway Tunnel is some 3.7km in length and was originally built as a canal tunnel enabling boats to pass freely between the river Medway and the river Thames. The tunnel was excavated between 1819 and 1824 through reasonably competent ...

During a Tunnel Boring Machine (TBM) project in Kunming city, Southwestern China the engineering geological conditions encountered at a distance of 7km consisted of folded, faulted, weak rocks, high ground stress and groundwater problems. The problems of collapse, ...

We analyse the statistical pattern of seismicity before a 1-2 10<sup>3</sup>m<sup>3</sup> 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 ...

This report, FEMA-351 has been developed by the SAC Joint Venture under contract to the Federal Emergency Management Agency (FEMA) to provide structural engineers with recommended criteria for evaluation of the probable performance of existing steel moment-frame ...
