Rupture zones in the area of the 17.08.99 Izmit (NW Turkey) large earthquake (Mw 7.4) and stress changes caused by its generation 总被引：1，自引：0，他引：1
The Mw 7.4 Izmit earthquake of 17 August 1999 struck a part ofthe North Anatolian fault in the area of Izmit Bay (NW Turkey). Historicalinformation shows that the fault which moved during the generation of thisearthquake consists of two fault segments moved during the generation oflarge (M 7) earthquakes in 1719 and 1754, respectively. Since then onlythe central part (between Izmit and Lake Sapanca) of this fault ruptured bythe generation of a smaller shock (M = 6.6) in 1878.The spatial stress variations based on the calculation of changes in theCoulomb Failure Function (CFF) associated with this earthquake aresupported by the distribution of strong aftershock foci. Large positive valuesof CFF to the east and west of the mainshock epicenter are inagreement with the notion that secondary faults were triggered there by thegeneration of the main event. Large positive values of CFF are alsoobserved in the adjacent western fault segment where the 1766 event wasgenerated, evidencing the occurrence of the next strong earthquake in thissegment. 相似文献

Microearthquake activity associated with underground coal-mining in Buchanan County,Virginia, U.S.A.
G. A. Bollinger 《Pure and Applied Geophysics》1989,129(3-4):407-413
Microearthquake activity (impulsive, transient seismic events, with durations up to several seconds at a distance of 500 m, that exhibit a coda with a shift toward lower frequencies with increasing time) was monitored for a three-month period by a single seismograph sited directly above an undergound longwall mine in the coal-mining region of Buchanan County, Virginia, U.S.A. The purpose of this investigation was to determine if precursory increases in microseismicity prior to cavings (subsidence) of overburden in the mine were present and, if so, could they be detected by surface seismographic observations. The first two recording weeks were prior to the beginning of coal removal operations at the monitored mine. A comparision of the before and after levels of microearthquake occurrence indicated a sevenfold increase to about seven seismic events/hour that was attendant with the development of the time over the level of the background, non-coal-mining period seismicity.A total of over 15,000 microearthquakes were recorded during the monitoring period, most of which occurred during the actual coal-mining operations. The workday rate exceeded 30 seismic events/hour in contrast with the non-workday rate of about seven such events/hour. Rock and coal fracturing ahead of the mine plow are believed to be the primary cause of the majority of these very small seismic events. Cavings and rockbursts (violent eruptions that propel rock debris into the mine) also contributed to the total seismic activity. It appears that cavings, some of which were large enough to be felt on ground surface, are the primary source of the non-plowing related seismicity as larger free surface areas are opened underground. Any seismic activity premonitory to cavings, however, was effectively masked by the high workday rate. Thus, the use of surface seismic monitoring, in an attempt to document any increases of localized seismicity precursory to cavings, failed in this instance.The exact location of the mine and the survey dates are not given in this paper at the request of the mine operator. 相似文献

Sensitivity of a seismically active reservoir to low-amplitude fluctuations: Observations from Lake Jocassee,South Carolina 总被引：3，自引：0，他引：3
Kusala Rajendran 《Pure and Applied Geophysics》1995,145(1):87-95
Relation between water level changes and pattern of seismicity is an important consideration in studies of Reservoir Induced Seismicity (RIS). Sensitivity of the Regions around Lake Jocassee to small fluctuations in the lake level is presented in this paper. The seismic source regions in the area around the lake seem to be sensitive to changes in the lake level as small as 1 to 1.5 m. Although such changes may produce stress changes of the order of only 0.1 bar, their influence on the spatial pattern of earthquakes seems to be quite perceptible. Observations of this type may help understand the threshold values of pore pressure/effective stress changes that can activate fault zones under high fluid pressure. 相似文献
