Magnitude Scaling of Induced Earthquakes
Presented are the results of an earthquake magnitude homogenization exercise for several datasets of induced earthquakes. The result of this exercise is to show that homogeneous computation of earthquake momentand local-magnitude is useful in hazard assessment of Enhanced Geothermal Systems (EGSs). Data include records from EGSs in Basel (Switzerland), Soultz (France) and Cooper Basin (Australi...
متن کاملGlobal frequency of magnitude 9 earthquakes
For decades seismologists have sought causal relationships between maximum earthquake sizes and other properties of subduction zones, with the underlying notion that some subduction zones may never produce a magnitude ~9 or larger event. The 2004 Andaman Mw 9.2 earthquake called into question such ideas. Given multicentury return times of the greatest earthquakes, ignorance of those return time...
متن کاملShort Note Constant Stress Drop from Small to Great Earthquakes in Magnitude-Area Scaling
Earthquakes span a tremendous range of scales, more than 5 orders of magnitude in length. Are earthquakes fundamentally the same across this huge range of scales, or are the great earthquakes somehow different from the small ones? We show that a robust scaling law seen in small earthquakes, with stress drops being independent of earthquake size, indeed holds for great earthquakes as well. The s...
متن کاملUnified scaling law for earthquakes.
We show that the distribution of waiting times between earthquakes occurring in California obeys a simple unified scaling law valid from tens of seconds to tens of years. The short time clustering, commonly referred to as aftershocks, is nothing but the short time limit of the general hierarchical properties of earthquakes. There is no unique operational way of distinguishing between main shock...
متن کاملThe magnitude distribution of declustered earthquakes in Southern California.
The binned distribution densities of magnitudes in both the complete and the declustered catalogs of earthquakes in the Southern California region have two significantly different branches with crossover magnitude near M = 4.8. In the case of declustered earthquakes, the b-values on the two branches differ significantly from each other by a factor of about two. The absence of self-similarity ac...
