Engineers may have found a way to measure displacement between floors of multistory buildings cheaply, accurately and in real-time, paving the way for quick analysis of the stability of critical infrastructure (e.g. hospitals, airports, water treatment plants) in the event of an earthquake.
A new image of the ground deformation, a rich and enigmatic foreshock sequence, aftershock trends we can explain, and others that are more elusive. This is also the time see how Temblor app’s hazard forecast for Ridgecrest fared.
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.

Two deadly and damaging quakes late last month were probably unrelated to each other.
A new model joins two others in confirming the hazard posed by the tectonic forces that are squeezing and shearing greater LA.
This squeeze was likely behind the 1971 Sylmar, 1987 Whittier Narrows and 1994 Northridge thrust earthquakes
