The opinions expressed in this PWSRCAC commissioned report are not necessarily those of PWSRCAC. The 1964 earthquake demonstrated that the Valdez area is subject to enormous earthquakes and coeval tsunamis. The geologic record of prehistoric earthquakes and tsunamis in the Valdez area has not previously been studied. Historic and prehistoric paleotsunami deposits were identified during this stu...

BACKGROUND On January 12, 2010, a devastating 7.0 magnitude earthquake struck the West Department of Haiti, killing more than 200,000 people and injuring or displacing many more. This disaster threatened continuity of HIV care and treatment services. OBJECTIVES This case study examined the effect of the devastating 2010 earthquake in Haiti on attrition from the HIV antiretroviral therapy (ART...

The current situation in earthquake space research indicates a few phenomena, related with earthquake: Earth's deformation, surface temperature, gas and aerosol content, electromagnetic disturbances in ionosphere. Both horizontal and vertical deformations scaled about tens centimetres and meters after the shock. Such deformations are recorded by InSAR technique with confidence. Pre-earthquake d...

During the June 27, 1998 Adana (Turkey) earthquake, only one strong-motion record was retrieved in the region where the most damage occurred. This single record from the station in Ceyhan, approximately 15 km from the epicenter of that earthquake, exhibits characteristics that are related to the dominant frequencies of the ground and structures. The purpose of this paper is to explain the cause...

This paper demonstrates a novel approach for learning about earthquake victims behavioral responses to an emergency situation in the immediate aftermath of an earthquake. Researchers developed an emergency scenario that describes students’ reactions following a magnitude 7.8 earthquake that leads to complications that escalate over eight episodes. Subjects were assigned to scenario simulation g...

Focusing on soil liquefaction, the seismic records during the Niigata-ken earthquake in 1964, the southern Hyogo prefecture earthquake in 1995 and the 2011 off the Pacific coast of Tohoku earthquake are analyzed by the non-stationary Fourier spectra. The shift of dominant frequency in the seismic record of Kawagishi-cho during the Niigata-ken earthquake is evaluated based on the time-variant pr...

This paper investigates the elastic-plastic seismic behavior of long span cable-stayed steel bridges through the plane finite-element model. Both geometric and material nonlinearities are involved in the analysis. The geometric nonlinearities come from the stay cable sag effect, axial force-bending moment interaction, and large displacements. Material nonlinearity arises when the stiffening ste...

Abnormal increases in radon ((222)Rn, half-life = 3.82 days) activity have occasionally been observed in underground environments before major earthquakes. However, (222)Rn alone could not be used to forecast earthquakes since it can also be increased due to diffusive inputs over its lifetime. Here, we show that a very short-lived isotope, thoron ((220)Rn, half-life = 55.6 s; mean life = 80 s),...

On 11 March 2011, a devastating earthquake struck off the coast of Japan, causing blustering tsunami that swept over the northeast coast of the country. Many struggled to evacuate from their homes, schools, and workplaces as 8- to 9-m-tall tsunami rapidly reached the coast within half an hour after the earthquake (Emergency Disaster Response Headquarters). The officials reported a record-breaki...
