WHO is coordinating the response to the health emergency with the Nepal government following the devastating 7.8 magnitude earthquake that struck the Himalayan kingdom on 25 April, killing more than 8000 people and injuring more than 18 000 (as of 12 May). Repeated aftershocks, including another major earthquake registering 7.3 on the Richter scale on 12 May, have also been recorded, putting th...

The stability of nonlinear stochastic dynamical system is a theoretically prominent problem, as it is of great theoretical and practical significance to many projects in reality. Firstly, the author established the basic formula. Secondly, he researches the stability theory of non-linear stochastic dynamical system, and discusses the stability criterion of null solution stability and nonlinear ...

G reat earthquakes of magnitude 8.5 or larger occur infrequently. For a nearly 40-y period after the February of 1965 M 8.7 Rat Islands, Alaska earthquake, the world did not experience a single great earthquake; however, in the 7 y since late December of 2004, there have been a barrage of five great earthquakes. These earthquakes include the 2004 M 9.1 Sumatra, Indonesia earthquake; the 2005 M ...

Spudich (Editors), Earthquake Source Physics and Earthquake Precursors. Tectonophysics. 211: 61-83. Plate tectonics and the seismic gap hypothesis provide the framework for long-term earthquake forecasting of plate boundary earthquakes. Unfortunate...

The BSPS (Bantuan Stimulan Perumahan Swadaya) program organized by the Directorate General of Housing Ministry Public Works and is a implemented as form improving quality self-help housing. Although simple, building like this requires sufficient resistance to earthquakes. results calculation earthquake that begins with loading roof obtained live load 1.38 N, super dead 0.75 132102.5 N.

Architectural design is an interdisciplinary process which involves multiple stages that are interconnected. In this process, it common for major decisions to be changed during the final stage, analysis of structural system. After making substantial corrections, architect has revisit early stages, preliminary project. This back-and-forth can result in significant losses time and cost. The propo...

Over 2000 earthquakes happen every year in Japan, so that this country is often called earthquake-ridden (Government of Japan, 2006). There exists a serious problem to prevent the occurrence of earthquake-induced disasters, such as fire, short-circuits, gas leakage, etc. With the recent advent of nation-wide telecommunication networks, real-time earthquake information can be received at every h...

Goals of this preliminary study are to better understand (1) earthquake performance of wood-frame shear walls carrying gravity loads, compared with walls without gravity load, and (2) performance of walls subjected to a sequence of earthquake motions, compared with walls subjected to a single earthquake. Tests with simulated earthquake ground motions were conducted on 2,440 by 2,440-mm (8 by 8-...
