Roland Piquepaille writes "The vast majority of the earthquakes are located underneath the oceans where they are not recorded because of a lack of instruments. This is why the Woods Hole Oceanographic Institution (WHOI) has developed a new kind of ocean bottom seismometers (OBSs) to record both small and large earthquakes on the sea floor. Forty of them will be deployed at the beginning of 2007 in an area of the Eastern Pacific Ocean known to have large earthquakes. One goal of this one-year mission is to better understand earthquake processes, but this technology could soon be used to better monitor other parts of the oceans.
