Understanding Animal Detection of Precursor Earthquake Sounds
We use recent research to provide an explanation of how animals might detect earthquakes before they occur. While the intrinsic value of such warnings is immense, we show that the complexity of the process may result in inconsistent responses of animals to the possible precursor signal. Using the results of our research, we describe a logical but complex sequence of geophysical events triggered...
متن کاملEarthquake Ruptures on Rough Faults
Natural fault surfaces exhibit roughness at all scales, with root-mean-square height fluctuations of order 10−3 to 10−2 times the profile length. We study earthquake rupture propagation on such faults, using strongly rate-weakening fault friction and offfault plasticity. Inelastic deformation bounds stresses to reasonable values and prevents fault opening. Stress perturbations induced by slip o...
متن کاملOn Earthquake Prediction in Japan
Japan's National Project for Earthquake Prediction has been conducted since 1965 without success. An earthquake prediction should be a short-term prediction based on observable physical phenomena or precursors. The main reason of no success is the failure to capture precursors. Most of the financial resources and manpower of the National Project have been devoted to strengthening the seismograp...
متن کاملEarthquake!
On January 25, 1 week after the most devastating earthquake in Los Angeles history, the Southern California Hospital Council released the following status report: 928 patients evacuated from damaged hospitals. 805 beds available (136 critical, 669 noncritical). 7,757 patients treated/released from EDs. 1,496 patients treated/admitted to hospitals. 61 dead. 9,309 casualties. Where do we go from ...
متن کاملOn The Concord of Sweet Sounds
Analysis of music for its consonant and dissonant properties has been performed by philosophers, musicians, physicists, and mathematicians for centuries. Analysis of powerful models developed by these researchers can be simplified and strengthened using basic physical concepts. By observing standard musical waveforms on an oscilloscope and comparing them to standard mathematical models a new un...
