Confidence intervals for earthquake source parameters
S U M M A R Y We develop a method to obtain confidence intervals of earthquake source parameters, such as stress drop, seismic moment and corner frequency, from single station measurements. We use the idea of jackknife variance combined with a multitaper spectrum estimation to obtain the confidence regions. The approximately independent spectral estimates provide an ideal case to perform jackkn...
متن کاملLocal Tsunamis and Earthquake Source Parameters
A persistent problem in estimating the severity of local tsunamis generated by earthquakes is explaining the great event-to-event variability of tsunami run-up heights relative to the magnitude of the earthquake. Undoubtedly, there is always variability in run-up that is dependent on local bathymetry. However, many earthquakes in recent years have produced unexpectedly high local run-up heights...
متن کاملRapid Assessment of Earthquake Source Characteristics
Recent studies emphasize the rapid assessment of earthquake source properties, such as moment magnitude, to help alleviate the impact of earthquakes. Depending on local crustal structure, earthquakes occurring at different depths can differ greatly in high-frequency motions, which emphasizes the importance in constraining focal depth for the predictions of strong motions. For large earthquakes,...
متن کاملSource Parameters of the Shallow 2012 Brawley Earthquake , Imperial Valley
Resolving earthquake parameters, especially depth, is difficult for events occurring within basins because of issues involved with separating source properties from propagational path effects. Here, we demonstrate some advantages of using a combination of teleseismic and regional waveform data to improve resolution following a bootstrapping approach. Local SS-S differential arrivals from a fore...
متن کاملScaling Relations for Earthquake Source Parameters and Magnitudes
A data set of 41 moderate and large earthquakes has been used to derive scaling rules for kinematic fault parameters. If effective stress and static stress drop are equal, then fault rise time, z, and fault area, S, are related by z = 16S1/2/(7~3/2~8), where ,8 is shear velocity. Fault length (parallel to strike) and width (parallel to dip) are empirically related by L = 2W. Scatter for both sc...
