The Mw 7.9 Denali fault earthquake in central Alaska of 3 November 2002 triggered earthquakes across western North America at epicentral distances of up to at least 3660 km. We describe the spatial and temporal development of triggered activity in California and the Pacific Northwest, focusing on Mount Rainier, the Geysers geothermal field, the Long Valley caldera, and the Coso geothermal field...
The opinions or assertions are those of the author and do not necessarily reflect those of the Army Medical Department or the Department of Defense. All countries came into Egypt, to Joseph, to buy grain, because the famine was severe in all the earth Genesis 41:57 Since the beginning of recorded history, governments have provided humanitarian assistance during disasters due to natural hazards....
Background and objective: numerous seismic hazard analysis studies are conducted annually using probabilistic methods throughout the world and Iran, which are usually different from the initial assumptions of analysis or software used. On the other hand, many researches are presented every year about new methods of earthquake hazard zoning, but so far these studies have not computed earthquake ...
To date, the October 2005 earthquake in Pakistan is the third most deadly natural disaster in the world since the 1976 earthquake in China that reportedly killed 255,000 people. 1 This issue of Prehospital and Disaster Medicine includes a report of the pattern of injuries in victims brought to the emergency relief hospital in Doraha, Mansehra. The manuscript presents a unique glimpse into the r...
the objective of this paper is to present a new method for protecting the lives of residents in catastrophic earthquake failures of unreinforced masonry buildings by introducing some safe rooms within the buildings. the main idea is that occupants can seek refuge within the safe rooms as soon as the earthquake ground motions are felt. the information obtained from the historical ground motions ...
Traditionally an earthquake is located by using the arrival times of P and S phases. This uses only a limited portion of the information on a seismogram. A large part of the information carried by the waveform is not used. In this study we investigate the applicability of the Time Reversed Acoustics (TRA) technique, and thus the whole waveform of the recorded signal, for earthquake locations an...
Background and Objectives: Earthquake can be the source of many secondary disasters. Fire is one of the most important secondary hazards after the earthquake. In some cases, post-earthquake fires, in urban areas, may cause far more severe damages than the earthquake itself. After the earthquake, the risk of fire is greatly increased due to the existence of sources of fire, such as arteries of g...
Natural disasters cause millions of death and disability and major financial losses world wide every year. The major concern of our health system has already been to reduce physical mortality and morbidity. While such events may be a considerable source of stress for the survivors and cause serious and long-lasting psychiatric complications. The purpose of this study was to assess the funct...
S U M M A R Y We present a re-evaluation of the seismological properties of the Aleutian ‘tsunami earthquake’ of 1946 April 1, characterized by a deceptively low conventional magnitude (7.4) in view of its catastrophic tsunami, both in the near and far fields. Relocation of 40 aftershocks show that the fault zone extends a minimum of 181 km along the Aleutian trench, in a geometry requiring a b...
