Evacuations in Bogotá and the suspension of transportation systems followed a magnitude-6.2 earthquake, which struck on or near where the North Andean Block grinds against South American Plate. The mainshock was followed just 15 minutes later by a magnitude-5.7 aftershock. Further large aftershocks remain a possibility
Aiming to make energy production safer, scientists developed a new model for forecasting earthquakes caused by oil and gas operations in the central U.S.
As of today, some 24 people are dead and 650 injured, and many more are unaccounted for in collapsed concrete buildings on the coastal plains surrounding the epicenter. The quake likely struck on a ‘blind thrust fault’ that does not reach the Earth’s surface but had nevertheless been previously identified by geologists.
Warnings were issued for the magnitude-4.5 and magnitude-4.7 quakes 5-6 seconds after they ruptured via ShakeAlert, and alerts reached beta testers of the MyShake app about 2 seconds later. While important progress, these intrinsic delays mean that those who experienced strong shaking received no warning. Alert delays may be longer as the number of alert recipients grows.
The recent acquittal of the TEPCO executives in the Fukushima power plant tragedy hearkens back to the trial of the Italian seismologists who were charged with negligence after the L’Aquila, Italy, earthquakes. Both events raise the question: How much do you prepare for the most dreadful disasters, which result from truly large or rare paroxysms of the Earth?

Based on the M 5.7 aftershocks thus far, there is a 3% chance that it could trigger a magnitude-6.5 or larger shock in the next year. The M 5.7 also brought a portion of the Marmara Fault significantly closer to failure.
The Magnitude 7.1 earthquake abruptly halted aftershocks on the M 6.4 cross fault. It also produced a far-flung aftershock sequence that touched the San Andreas, but refused to cross the Garlock Fault.
The 50-km-long rupture has triggered widely dispersed aftershocks. However, almost none of these struck on the faults that the M 7.1 brought closer to failure: The major Garlock Fault; or the Blackwater, Panamint Valley, or Sierra Nevada Faults.

The site of the 4th of July shock was stressed by the great 1872 Owens Valley quake and the 1992 Landers quake. Their overlapping stress lobes may have raised the stakes for this region.

While Japan is moving entire towns out of the tsunami zone in the wake of the 2011 Tohoku disaster, Oregon is doing the opposite, trading public safety for developer profits.
While no one quake can invalidate an earthquake hazard model, larger-than-expected quakes on both the Tohoku and Japan Sea coasts point to inadequacies in Japan’s national seismic model.
