The devastating effects of earthquakes have been demonstrated repeatedly in the past decade, through moderate and major earthquakes such as the October 1987 Whittier Narrows earthquake (5.9 on the Richter scale), the October 1989 Loma Prieta earthquake (7.1) and the January 1994 Northridge earthquake (6.7). While 'official' tallies of injuries and deaths are reported for each event, the numbers...

Abstract Peninsular Malaysia is tectonically situated on a stable craton (intraplate) and so far experiences relatively little earthquake activities, thus considered as region with low seismicity. This study uses data from 59 events obtained various sources in the period 1922 to 2020. The overall seismicity area expected due general intraplate setting. Earthquakes occurred onshore offshore of b...

[1] The 1999 Chi-Chi earthquake, Mw = 7.6, broke a major thrust fault along the western foothills of the Central Range of Taiwan. We have measured the horizontal coseismic displacement field by correlating optical satellite images acquired before and after the earthquake. These data reveal the fault trace and a clockwise rotation of surface displacements toward the north with much larger displa...

Central Sulawesi is an area that prone to earthquakes. The movement of the Palu Koro Fault trigger for most destructive earthquakes in region. This study aims analyze seismicity based on seismotectonic parameter b-value, coulomb stress changes and level risk 1996-2022 range. uses data from earthquake catalog USGS catalog. Data was then processed using Zmap v6 MATLAB obtain b-value maximum likel...

Co-seismic deformation of the ground can be measured from aerial views taken before and after an earthquake. As a test example we chose the area of the Kickapoo-Landers stepover along the 1992 Landers earthquake zone, using air photos in a scale of 1:40,000 scanned at 0.4 m in resolution. A pair of photos acquired after the earthquake is used to assess the accuracy and evaluate various sources ...

Power networks are among the most important infrastructures that without them, industrial, economic and social procedures will halt. Therefore, they should be planned for the most difficult conditions to provide services with minimum disruption. Power substations are of great importance to a power network, because any disruption in their components can produce extensive problems through the net...

OBJECTIVE On 11 March 2011, the Great East Japan Earthquake struck off Japan. Although some studies showed that the earthquake increased the risk of pneumonia death, no study reported whether and how much a tsunami increased the risk. We examined the risk for pneumonia death after the earthquake/tsunami. DESIGN This is an ecological study. SETTING Data on population and pneumonia deaths obt...

The great Sumatra–Andaman earthquake of 26 December 2004 (UTC 00:58:53) was a momentous event, whether measured by scientific or human standards. Sadly, what is currently regarded as the third largest earthquake in recorded history led to the worst tsunami disaster in recorded history, with the loss of more than 200,000 lives and devastation throughout the Bay of Bengal. About three months late...

Repeated earthquakes and explosions recorded at the San Andreas fault (SAF) near Parkfield before and after the 2004 M6 Parkfield earthquake show large seismic velocity variations within an approximately 200m-wide zone along the fault to depths of approximately 6 km. The seismic arrays were co-sited in the two experiments and located in the middle of a high-slip part of the surface rupture. Wav...

[1] The 25 October 2010 Mentawai, Indonesia earthquake (Mw 7.8) ruptured the shallow portion of the subduction zone seaward of the Mentawai islands, off‐shore of Sumatra, generating 3 to 9 m tsunami run‐up along southwestern coasts of the Pagai Islands that took at least 431 lives. Analyses of teleseismic P, SH and Rayleigh waves for finite‐fault source rupture characteristics indicate ∼90 s ru...
