Earthquakes are one of the most destructive natural hazards on our planet Earth. Hugh earthquakes striking offshore may cause devastating tsunamis, as evidenced by the 11 March 2011 Japan (moment magnitude Mw 9.0) and the 26 December 2004 Sumatra (Mw 9.1) earthquakes. Earthquake prediction (in terms of the precise time, place, and magnitude of a coming earthquake) is arguably unfeasible in the ...
BACKGROUND On February 27, 2010 a powerful earthquake followed by a tsunami stroke Chile. The study of mortality during this emergency can provide important public health information. AIM To describe the main characteristics of people who died during the earthquake and the following three months. MATERIAL AND METHODS Cross sectional analysis of death records databases obtained from Departme...
BACKGROUND The 2004 Niigata-Chuetsu earthquake of Japan caused considerable damage. We assessed long-term changes in psychological distress among earthquake victims during the period 5 years after the earthquake. METHODS The participants were people aged 18 years or older living in Yamakoshi, a community in Niigata Prefecture near the epicenter. A self-administered questionnaire survey was co...
OBJECTIVE Stress is thought to be one of the triggers of relapses in patients with inflammatory bowel disease (IBD). We examined the rate of relapse in IBD patients before and after the Great East Japan Earthquake. DESIGN A retrospective cohort study. SETTINGS 13 hospitals in Japan. PARTICIPANTS 546 ulcerative colitis (UC) and 357 Crohn's disease (CD) patients who received outpatient and ...
On May 23, 1989, a great earthquake struck a remote region of the South Pacific Ocean between New Zealand and Antarctica. The nearby islands are Macquarie Island, about 300 km south of the epicenter, and Campbell Island, almost 600 km east of the epicenter; the latter experienced shaking with intensity V. Fortunately, both islands are sparsely inhabited and litfie damage or injuries were report...
PURPOSE This study longitudinally investigated the changes of depressive symptoms among adolescent survivors over 2 years and a half after the 2008 Wenchuan earthquake in China, as well as the predictive effects of demographic characteristics, earthquake exposure, negative life events, social support, and dispositional resilience on the risk of depressive symptoms at two time points after the e...
introduction natural hazards as recurring phenomenon have always existed in human life and will in the future, too. nowadays natural hazards occur throughout the world, but their impacts have been increasing and are generally much greater in developing countries than in developed ones. earthquake is a kind of natural hazard that has the most damages for humankind. earthquakes pose inevitable ri...
A rapid, holistic view of earthquake disasters begins with earthquake location and magnitude, alerted by seismic networks. The initial source characteristics, along with any available ground-shaking observations, can be used to rapidly estimate the shaking extent, its severity (e.g., ShakeMap), and its likely impact to society, for example, employing the U.S. Geological Survey's Prompt Assessme...
[1] The 25 October 2010 Mentawai, Indonesia earthquake (Mw 7.8) ruptured the shallow portion of the subduction zone seaward of the Mentawai islands, off‐shore of Sumatra, generating 3 to 9 m tsunami run‐up along southwestern coasts of the Pagai Islands that took at least 431 lives. Analyses of teleseismic P, SH and Rayleigh waves for finite‐fault source rupture characteristics indicate ∼90 s ru...
The catastrophic earthquake, 7.3 on the Richter scale, occurred on September 21, 1999. The 921 Earthquake was a terrifying disaster that caused numerous casualties in Central Taiwan. It is the severest earthquake in a recent hundred years. The land morphology and topography changed greatly with such features as land upheaval, river blockades and lakes dammed by debris in many locations. Severe ...
