The Sierra Madre fault, along the southern flank of the San Gabriel Mountains in the Los Angeles region, has failed in magnitude 7.2 to 7.6 events at least twice in the past 15,000 years. Restoration of slip on the fault indicates a minimum of ~4.0 m of slip from the most recent earthquake and suggests a total cumulative slip of ~10.5 m for the past two prehistoric earthquakes. Large surface displacements and strong ground-motions resulting from M > 7 earthquakes within the Los Angeles region are not yet considered in most seismic hazard and risk assessments.

Was the March 11 Japan quake forecastable? A team of scientists involved in research on earthquake precursors has released a pre-publication copy of a paper analyzing distinct precursor signals in the atmosphere and ionosphere in the days preceding the disaster. As we have presented on this website, the science behind earthquake precursors has been definitively established, while the official government position in the United States has been to ignore or suppress such work, and to eliminate necessary monitoring programs, as has been most recently carried out by Presidential dictat under Obama. Oyang Teng reviews the argument made by the authors of the recent paper, a link to which can be found here.
