Velocity structure of the Andes of central Peru from locally recorded earthquakes
Arrival-times of local events recorded during two short term seismic ficd investigations in ccntral Peru are used to determine the P and S velocity structures above the slab, in a segment of the Andes where the subduction is horizontal. The velocities in the upper-crust can be related to the sedimentary cover. The Moho depth is estimated to be nbuut 50 km below the western part of the sub-Andea...
متن کاملPropagating Waves in the Steel, Moment-Frame Factor Building Recorded during Earthquakes
Wave-propagation effects can be useful in determining the system identification of buildings such as the densely instrumented University of California, Los Angeles, Factor building. Waveform data from the 72-channel array in the 17-story moment-resisting steel frame Factor building are used in comparison with finiteelement calculations for predictive behavior. The high dynamic range of the 24-b...
متن کاملMacroeconomic Earthquakes †
In the common jargon used by non-specialist commentators in newspapers or TV programs, business cycle downturns are sometimes described in terms of economic collapses, crashes or even earthquakes. Does these comparisons make any sense but for literary license? In particular, are economic recessions and recoveries governed at large by the same statistical law underlying earthquakes' occurrence? ...
متن کاملLaboratory earthquakes
We report on the experimental observation of the phenomenon of, spontaneously nucleated, supershear rupture and on the visualization of the mechanism of subRayleigh to supershear rupture transition in frictionally-held interfaces. The laboratory experiments mimic natural earthquakes. The results suggest that under certain conditions supershear rupture propagation can be facilitated during large...
متن کاملGlacial earthquakes.
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,...
