Rapid 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 کاملImaging Earthquake Source Complexity
Abstract Recent improvement in analysis methods, computational resources, and seismological and geological observations enable us to image earthquake source in detail. This paper reviews various studies for each component of source imaging: model parameterization, data, theoretical wave calculation, and optimization. Differences in analysis in each of these aspects can lead to significant diffe...
متن کاملReview of the source characteristics of the Great Sumatra – Andaman Islands earthquake of 2004
The December 26, 2004 Sumatra–Andaman Island earthquake, which ruptured the Sunda Trench subduction zone, is one of the three largest earthquakes to occur since global monitoring began in the 1890s. Its seismic moment was M0 = 1.00 · 10–1.15 · 10 Nm, corresponding to a moment-magnitude of Mw = 9.3. The rupture propagated from south to north, with the southerly part of fault rupturing at a speed...
متن کاملassessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Amplitude of the Earth's free oscillations and longperiod characteristics of the earthquake source
Amplitude spectra of the spheroidal modes 0St (1 = 2-40) excited by the 1960 Chilean earthquake and observed at Pasadena, Los Angeles, and Isabella show distinct holes at oSxo (T = 580 s) and 0S:x (T = 336 s). These holes can be explained as an interference pattern caused by a composite source consisting of a finite propagating source (main shock) and a slow precursory source, 15 rain before th...
