Variability in earthquake stress drop and apparent stress
[1] We apply empirical Green’s function coda‐based analysis to four earthquake sequences in Japan that span a magnitude range of 1.8 to 6.9, to measure radiated energy, corner frequency and stress drop. We find no systematic dependence of apparent stress or stress drop on seismic moment for these sequences, and find they both are log‐normally distributed; however, we identify several anomalous ...
متن کاملEarthquake Repeat Time and Average Stress Drop
Existing data on source parameters of large crustal earthquakes (subduction events are not considered here) over a wide range of repeat imes indicate that, for a given magnitude (Ms or Mw), earthquakes with long repeat times have shorter fault lengths than those with short repeat imes. A shorter fault length for a given magnitude indicates a larger average stress drop which reflects the average...
متن کاملDynamic Stress Changes during Earthquake Rupture
We assess two competing dynamic interpretations that have been proposed for the short slip durations characteristic of kinematic earthquake models derived by inversion of earthquake waveform and geodetic data. The first interpretation would require a fault constitutive relationship in which rapid dynamic restrengthening of the fault surface occurs after passage of the rupture front, a hypothesi...
متن کاملPlaque rupture: plaque stress, shear stress, and pressure drop.
tenosis (1). The Hypertension Genetic Epidemiology Network HyperGEN) Study Group conducted a genome-wide linkage can on aortic valve sclerosis (2) that deserves to be discussed. This yperGEN cohort was a substudy of a larger National Heart, ung, and Blood Institute program, the Family Blood Pressure rogram, designed to search for hypertension/blood pressure enes. The authors reported familial a...
متن کاملProperties of Dynamic Earthquake Ruptures With Heterogeneous Stress Drop
Earthquake rupture is a notoriously complex process, at all observable scales. We introduce a simplified semi-dynamic crack model to investigate the connection between the statistical properties of stress and those of macroscopic source parameters such as rupture size, seismic moment, apparent stress drop and radiated energy. Rupture initiation is treated consistently with nucleation on a linea...
