The accelerograms of the 1999 Chamoli earthquake and nine of its aftershocks, which occurred in Uttaranchal Himalaya, have
been analyzed to investigate their source parameters, the site amplification functions and the average effective shear-wave
quality factor Qseff in the region. The fault plane solution of the main shock is obtained using the spectral amplitudes of SH waves (approximated
by transverse components of accelerograms) of the high-energy packets observed in the accelerograms of the main shock. It
is found to be comparable with the reported solutions in other studies. Similarly the other source parameters (viz., seismic
moment = (5.03±1.7) × 1025 dyne-cm, stress drop = 65 bars, source duration = 5.2 s and moment magnitude = 6.4) estimated for the main shock are consistent
with the values obtained in other studies. The stress drops estimated for the aftershocks vary from 23 bars to 153 bars and
the seismic moment from 1.4 × 1023 dyne-cm to 2.9 × 1023 dyne-cm. The average estimated values of the effective shear-wave quality factor Qseff vary from 655±359 in the Uttaranchal sector of Himalaya and 1475±130 in the Delhi region. In general, the Qseff value increases with an increase in the epicentral distance reflecting the penetration of the waves into deeper layers of
the crust as the epicentral distance of the observation point increases. These values of Qseff indicate that in general the curst is at low temperatures that will promote brittle behavior and conditions for episodic
failure as compared to creep, under the accumulated strains from plate collision at the Himalaya plate boundary. The site
amplification characteristics at sites have been identified from the frequency bands of significant amplification observed
in the spectral ratios of the horizontal to the vertical component records. The decay of peak ground acceleration (PGA) values
with distance has been investigated using the empirical regression curves vis-à-vis the site amplification factors. 相似文献

昆仑山8.1级地震在四川省地震地下水观测网中引起了大多数深井水位记录的大幅度波动,数字化水位仪LN-3和大多数浮子式机械水位仪SW40-1均记录到水震波,同一口井两种不同仪器水震波的记录结果有差异,相邻井的记录不同,同震阶变结果表明除北部受张应力外主要受压应力,地震还引起了红旗水库水体冒泡,起大旋涡,库水东西对流的现象。 相似文献

The Yajiang earthquake sequence in 2001, with the major events of Ms5.1 on Feb. 14 and of Ms6.0 on Feb.23, are significant events in the Sichuan region during the last 13 years. Eighty-eight earthquakes in the sequence with at least 5 distinct onset parameters for each recorded by the Sichuan Seismic Network in the period of Jan. 1 through June 30,2001 were chosen for this study. The events are relocated and the focal mechanism is derived from P-wave onsets for 13 events with relatively larger magnitudes. The focal depth of all earthquakes fall between a range of 2km to 16km, with dominant distribution between 9km to 11km. Theforeshocks, the Ms5.1 earthquake and the Ms6.0 earthquake and their aftershocks are all located close to the Zihe fault and the dominant epicentral distribution is in NW direction, identical to that of the fault. The fracture surface of the focal mechanism is determined in accordance to the mass transfer orientation in the recent earth deformation field in the Yajiang region. The P axes of the principal compressive stress in focal mechanism solutions of the 13 events show bigger vertical components, and the horizontal projection trending SE. The earthquakes are of left-lateral, strike-slip normal, and normal strike-slip types. The rupture surface of most earthquakes strike NW-SE, dipping SW. Based on the above information, we conclude that the Zihe fault that crosses the earthquake area, striking NW and dipping SW, is the seismogenic fault for the Yajiang earthquake sequence. 相似文献
