INTRODUCTION Few studies have focused on the mental health consequences of indirect exposure to disasters caused by naturally occurring hazards. The present study assessed indirect exposure to the 2010 earthquake in Haiti among Haitian-Americans now living in Miami; these subjects had no direct exposure to the earthquake, but retained their cultural identity, language, and connection to family ...

The central United States has undergone a dramatic increase in seismicity over the past 6 years (Fig. 1), rising from an average of 24M ≥3 earthquakes per year in the years 1973–2008 to an average of 193M ≥3 earthquakes in 2009–2014, with 688 occurring in 2014 alone. Multiple damaging earthquakes have occurred during this increase including the 2011M 5.6 Prague, Oklahoma, earthquake; the 2011 M...

Abstract Fault geometry affects the initiation, propagation, and cessation of earthquake rupture, as well as, potentially, statistical behavior sequences. We analyze 18,250 (?0.27 < M 4.4) earthquakes 2016–2019 Cahuilla, California, swarm and, for first time, use these high-resolution locations to map, in detail, roughness across an active fault surface at depth. find that strike-slip is...

Geophysical imaging by using attenuation property of multichannel seismic reflection data was tested to map spatial variation of physical properties of rocks in a volcanic area. The study area is located around Miyakejima volcanic island, where an intensive earthquake swarm was observed associated with 2000 Miyakejima eruption. Seismic reflection survey was conducted five months after the swarm...

Paleoseismological trenching was performed along the Düzce fault providing some preliminary insight about its seismogenic behavior. Dating based on radiocarbon analysis of peat samples collected from trenches and suggested seven earthquakes have occurred since 1740 BC. Integrating date constraints events exposed in suggests a periodical earthquake recurrence model. According to linear sequentia...

The probability of extreme events such as an earthquake, fire or blast occurring during the lifetime a structure is relatively low but these can cause serious damage to well human life. Due significant consequences for occupant and structural safety, accurate analysis response structures exposed required their design. Some may occur consequence another hazard, example, due failure electrical sy...

Many engineering applications require the calculation of the distribution of the maximum of a number n of indendent, identically distributed (iid) variables. A typical situation is the design of a system for the “n-year demand” when the maximum demands in different years are iid (design of a dam for the n-year flood, design of an offshore platform for the n-year wave, design of a building for t...

[1] The Mw 6.6, 26 December 2003 Bam (Iran) earthquake was one of the first earthquakes for which Envisat advanced synthetic aperture radar (ASAR) data were available. Using interferograms and azimuth offsets from ascending and descending tracks, we construct a three-dimensional displacement field of the deformation due to the earthquake. Elastic dislocation modeling shows that the observed def...

Using the simple ETAS branching model of seismicity, which assumes that each earthquake can trigger other earthquakes, we quantify the role played by the cascade of triggered seismicity in controlling the rate of aftershock decay as well as in the overall level of seismicity in the presence of a constant external seismicity source. We show that, in this model, the proportion of triggered seismi...
