The moment magnitude (Mw) 7.9 Fort Tejon earthquake of 1857, with a approximately 350-kilometer-long surface rupture, was the most recent major earthquake along the south-central San Andreas Fault, California. Based on previous measurements of its surface slip distribution, rupture along the approximately 60-kilometer-long Carrizo segment was thought to control the recurrence of 1857-like earth...

The excavation in the Wanfung area has provided evidence for at least three earthquake ruptures, including the 1999 ChiChi one. The Chi-Chi earthquake formed an obviously major reverse fault, backthrust, and several minor normal faults, accompanied by a teardrop-shape anticline in the fault tip. Paleoseismic ruptures I and II show the vertical displacement of 0.4 m and 1.2 m, respectively, whic...

Three earthquake clusters that occurred in the direct vicinity of the southern terminus of the San Andreas Fault (SAF) in 2001, 2009, and 2016 raised significant concern regarding possible triggering of a major earthquake on the southern SAF, which has not ruptured in more than 320 years. These clusters of small and moderate earthquakes withM ≤ 4.8 added to an increase in seismicity rate in the...

The October 2005 earthquake in Pakistan created a new generation of "persons with disabilities" (PWDs) in the affected districts. A total of 741 people suffered spinal injuries while 713 underwent amputations. A comprehensive response was launched jointly by the Ministry of Health, Earthquake Reconstruction and Rehabilitation Authority and the World Health Organization involving rescue and reco...

OBJECTIVE The present study explored the impact a natural disaster has on human performance. BACKGROUND Previous research indicates that traffic accidents increase after disasters. A plausible explanation for this finding is that disasters induce cognitive disruption and this disruption negatively affects performance (e.g., driving quality). METHOD A total of 16 participants (7 men and 9 wo...

On March 11, 2011, Japan was consecutively hit by three unprecedented disasters caused by The Great East Japan (Tohoku) Earthquake: an earthquake of magnitude 9.0, an incredibly powerful tsunami, and a nuclear power plant breakdown. As Japan had experienced The Great HanshinAwaji Earthquake in 1995, we were prepared to provide the victims with appropriate medical care to some extent. Neverthele...

The paper presents the approach for earthquake hazard, exposure, vulnerability and risk assessment for Nepal. The approach amalgamates various scientific streams, which are structured and integrated on GIS platform. The exposure, vulnerability and risk assessment are carried out for primary sectors including population, housing, education, hospital, industry, power and roadways. The risk assess...

The quantification of spatial heterogeneity can be used to examine the structure of ecological systems. The 2008 Wenchuan earthquake caused severe vegetation damage. In addition to simply detecting change, the magnitude of changes must also be examined. Remote sensing and geographic information system techniques were used to produce landscape maps before and after the earthquake and analyze the...

S U M M A R Y Geometrical properties of an earthquake population can be described by summation of seismic potency tensors that provide a strain-based description of earthquake focal mechanisms. We apply this method to∼170 000 potency tensors for 0<ML ≤ 5 southern California earthquakes recorded between January 1984 and June 2003. We compare summed tensors for populations defined by faulting reg...
