From the late 1900s onward, hydrocarbon exploitation has led to severe environmental footprints in Khuzestan province, Iran. However, no comprehensive study been conducted evaluate such issues. In this research, an inclusive analysis was performed investigate these impacts. To do this, first, two datasets related a 15-year period (2006–2021) were collated: satellite data from Sentinel-1 mission...

We study deep aseismic slip along the central section of the San Jacinto Fault, near the Anza Seismic Gap, in southern California. Elevated strain-rates following the remote Mw7.2 April 4, 2010 El Mayor-Cucapah and the local Mw5.4, July 7, 2010 Collins Valley earthquakes were recorded by Plate Boundary Observatory borehole strain-meters near Anza, and were accompanied by vigorous aftershock seq...

Abstract. Studies of seismicity induced by water level changes in reservoirs and lakes focus typically on well-documented contemporary records. Can such interactions be explored a historical timescale when the two data types suffer from severe uncertainties stemming different nature data, methods resolution? In this study, we show way to considerably improve correlation between interpolated rec...

Continuous geodetic measurements from convergent margins have shown that deep transient creep events can release large amounts of strain energy without detectable seismic shaking, and they are thus known as slow or silent earthquakes. Because subduction zones generate the largest earthquakes, seismic hazard assessment relies on understanding the degree to which slow earthquakes reduce the energ...

Waveform data from a borehole network of broadband seismographic stations have been used to study microearthquakes along the Parkfield segment of the San Andreas fault (SAF). Analysis of almost 10 years of such data demonstrates that much of the seismicity in this region consists of repeating sequences, quasiperiodic sequences of earthquakes that are essentially identical in terms of waveform, ...

S U M M A R Y We perform a comprehensive analysis of dynamic triggering around the Babaoshan and Huangzhuang-Gaoliying faults near Beijing, China. The triggered earthquakes are identified as impulsive seismic arrivals with clearP and S waves in 5 Hz high-pass-filtered three-component velocity seismograms during the passage of large amplitude body and surface waves of large teleseismic earthquak...

Abstract Source parameters represent key factors in seismic hazard assessment and understanding source physics of earthquakes. In addition to conventional grid search approach estimate parameters, other approaches have been used recently. This study uses a Bayesian framework, the Markov Chain Monte Carlo method, including uncertainty with inter-parameter correlations. The calculation method req...

Amplification corrections are presented for the finite-fault stochastic ground-motion simulation model; these corrections represent the total effect of the Los Angeles basin on the ground-motion spectra. Spectral amplification ratios were calculated by dividing the observed spectra for the 1994 Northridge and 1987 Whittier Narrows earthquakes, including shearand basin-generated waves, by the si...

In this study, I consider the ground motions generated by 11 moderate (Mw 4.0–5.6) earthquakes in the central and eastern United States that are thought or suspected to be induced by fluid injection. Using spatially rich intensity data from the U.S. Geological Survey “Did You Feel It?” system, I show the distance decay of intensities for all events is consistent with that observed for tectonic ...
