Effect 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...
متن کاملThe Partitioning of Radiated Energy and the Largest Aftershock of Seismic Sequences Occurred in the Northeastern Italy and Western Slovenia
We analyzed the most relevant seismic sequences occurred from 1977 to 2007 in the FriuliVenezia Giulia region (northeastern Italy) and western Slovenia. The 8 aftershock sequences were triggered by low to moderate magnitude earthquakes with mainshock duration magnitude ranging from 3.7 to 5.6. The b-value of the Gutenberg-Richter law varies from 0.8 to 1.1. The modified Omori’s modeling of the ...
متن کاملTitle: Radiated Energy and State of Stress during Earthquake Rupture
We determined the energy release in earthquakes using the data obtained from TriNet in southern California. We investigated the effects of the depth, the mechanism and the propagation path by examining the results for events with different mechanisms and depths. We found that the path and site effects dominate so much that these effects are not obvious. By far the most dominant is the path-site...
متن کاملRepresentations of the radiated energy in earthquakes
S U M M A R Y We investigate the representation of the radiated energy, E R, in earthquakes. In seismology E R is estimated from either far-field seismic waves or the stress and displacement on the fault plane. Although E R comes from the entire volume of the Earth, it can be expressed as an integral over the fault plane. However, the integrand cannot be given a simple physical meaning such as ...
متن کاملEnergy radiated from a fluctuating selfdual string
We compute the energy that is radiated from a fluctuating selfdual string in the large N limit of AN−1 theory using the AdS-CFT correspondence. We find that the radiated energy is given by a nonlocal expression integrated over the string world-sheet. We also make the corresponding computation for a charged string in six-dimensional classical electrodynamics, thereby generalizing the Lienard-Wie...
