We study dynamic rupture propagation on flat faults using 2D plane strain models featuring strongly rate-weakening fault friction (in a rate-and-state framework) and off-fault Drucker–Prager viscoplasticity. Plastic deformation bounds stresses near the rupture front and limits slip velocities to ∼10 m=s, a bound expected to be independent of earthquake magnitude. As originally shown for rupture...

The 2015 Gorkha Nepal earthquake caused tremendous damage and loss. To gain valuable lessons from this tragic event, an earthquake damage investigation team was dispatched to Nepal from 1 May 2015 to 7 May 2015. A unique aspect of the earthquake damage investigation is that first-hand earthquake damage data were obtained 6–11 days after the mainshock. To gain deeper understanding of the observe...

This paper is about short review of earthquake statistics and efforts for earthquake mitigation, hazard and risk assessment studies in Pakistan. Pakistan and adjoining region lying between longitude 60 ̊E to 78 ̊E and latitude 20 ̊N to 45 ̊N are selected for the study as this region has a history of many large earthquakes because of its location in the region of intersection of three plates namely ...

Limb trauma is the most common among pediatric victims in earthquake. Compared with traumatic brain injury, which is frequent in earthquake, intracranial injury is rare, but it is the leading cause of death from trauma in earthquake. Thoracoabdominal crush injury, which often causes such crises as visceral hemorrhage, is also one of the main causes of death among pediatric victims in earthquake...

The study investigated the symptoms of posttraumatic stress disorder (PTSD) and associated risk factors among adult survivors 3 months after the 2008 Sichuan earthquake in China. One thousand five hundred sixty-three earthquake survivors in two communities participated in the study. The prevalence of probable PTSD was 37.8% and 13.0%, respectively, in the two communities that were affected diff...

This paper presents a notification system to identify earthquakes from firsthand reports published on Twitter. Tweets from target regions in Australia and New Zealand are checked for earthquake keyword frequency bursts and then processed to identify evidence of an earthquake. The benefit of our earthquake detector is that it relies on evidence of firsthand ‘felt’ reports from Twitter, provides ...

The objective of this study was to investigate the mediating role of coping strategies in the relationships between neuroticism, social support, and depression in two groups of adolescents: earthquake group and examination group. Adolescents facing earthquake stress (earthquake group, N=219) completed measures of neuroticism, perceived social support, coping strategies, and self-rating depressi...

The study of the Earth’s electromagnetic fields prior to the occurrence of strong seismic events has repeatedly revealed cases were transient anomalies, often deemed as possible earthquake precursors, were observed on electromagnetic field recordings of surface, atmosphere and near space carried out measurements. In an attempt to understand the nature of such signals several models have been pr...

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...

Taking advantage of computer technology and science that enable us to carry out a largescale numerical simulation, the authors have been simulating the whole phases of an earthquake, i.e., the generation and propagation of an earthquake, the response and damage of structures, and the human and society actions against the earthquake damages. This is the integrated earthquake simulation (IES). Wi...
