Reconciling Teleseismic and Regional Estimates of Seismic Energy
Estimates of the radiated seismic energy based on teleseismic and regional data often differ by up to an order of magnitude, with a tendency for regional estimates to be larger than teleseismic estimates for the same event. In this study we compare the velocity spectrum determined from teleseismic data after correction for radiation pattern and propagation effects, with the velocity spectrum de...

متن کاملRadiated Energy from the 16 October 1999 Hector Mine Earthquake : Regional and Teleseismic Estimates
The amount of seismic energy radiated from an earthquake is a key macroscopic parameter for understanding the physics of earthquakes. To resolve the important details of the earthquake process, we require more accurate estimates of energy than are currently available. In this study, we determine the energy radiated from the Mw 7.1 16 October 1999 Hector Mine, California, earthquake using region...
متن کاملCalibration of 3d Upper Mantle Structure in Eurasia Using Regional and Teleseismic Full Waveform Seismic Data
We present progress in the development of a new approach to develop and evaluate earth models at the regional scale that utilizes full waveform seismograms. We have implemented an approach which relies on a cascade of increasingly accurate theoretical approximations for the computation of the seismic wavefield, with the goal to develop a model of regional structure for a subregion of Southeast ...
متن کاملEffect of directivity on estimates of radiated seismic energy
[1] To accurately estimate the seismic energy radiated in an earthquake, it is important to use appropriate corrections for path and source effects. Using slip models obtained by inversion of seismic data, we examine the effect of directivity on estimates of radiated energy and develop a method to correct for this source effect. From our calculations we suggest that the directivity correction f...
