In most cases of reservoir-induced seismicity, seismicity follows the impoundment, large lake-level changes, or filling at a later time above the highest water level achieved until then. We classify this as initial seismicity. This ‘‘initial seismicity’’ is ascribable to the coupled poroelastic response of the reservoir to initial filling or water level changes. It is characterized by an increa...

The results of research on some aspects of coastal dynamics during earthquakes, carried out in the Institute of Hydro-Engineering, are summarized. The attention is focused on the liquefaction-related phenomena, like modeling the earthquake-induced generation of pore-pressures and subsequent liquefaction of subsoil, the behavior of liquefied soil, underwater landslides, sinking of structures in ...

We have detected dozens of previously unknown, moderate earthquakes beneath large glaciers. The seismic radiation from these earthquakes is depleted at high frequencies, explaining their nondetection by traditional methods. Inverse modeling of the long-period seismic waveforms from the best-recorded earthquake, in southern Alaska, shows that the seismic source is well represented by stick-slip,...
