Local 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 کاملConfidence 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 کاملCAPjoint , A Computer Software Package for Joint Inversion of Moderate Earthquake Source Parameters with Local and
Accurate earthquake source parameters such as fault mechanism, depth, and moment magnitude are not only important in seismic-hazard assessment, but also are crucial to studies of earthquake rupture processes and seismotectonics. Although large earthquakes (Mw 7+) may cause substantial damage, they occur less frequently. In contrast, moderate earthquakes (Mw 5.0–6.5) occur with much higher frequ...
متن کاملPotential of Landsat-8 spectral indices to estimate forest biomass
Forest ecosystems are among the largest terrestrial carbon reservoirs on our planet earth thus playing a vital role in global carbon cycle. Presently, remote sensing techniques provide proper estimates of forest biomass and quantify carbon stocks. The present study has explored Landsat-8 sensor product and evaluated its application in biomass mapping and estimation. The specific objectives were...
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...
