Macroeconomic 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,...
متن کاملp-Lambda-bounded variation
A characteriation of continuity of the $p$-$Lambda$-variation function is given and the Helly's selection principle for $Lambda BV^{(p)}$ functions is established. A characterization of the inclusion of Waterman-Shiba classes into classes of functions with given integral modulus of continuity is given. A useful estimate on modulus of variation of functions of class $Lambda BV^{(p)}$ is found.
متن کاملSpatiotemporal Correlations of Earthquakes
Statistical properties of earthquakes are studied both by the analysis of real earthquake catalog of Japan and by numerical computer simulations of the spring-block model in both one and two dimensions. Particular attention is paid to the spatiotemporal correlations of earthquakes, e.g., the recurrence-time distribution or the time evolution before and after the mainshock of seismic distributio...
