Case study-Gujarat earthquake rehabilitation program • Rapid post earthquake reconnaissance to assess impact, and development of retrofitting techniques for damaged structures • Evaluation of earthquake ground motions data, seismic hazard and vulnerability, and causes of damage • Development of design guidelines for new constructions and evaluation of structural designs • Training Jul 11, 2024 · effective mitigation measures, such as slope stabili zation and drainage improvements. , 2006; Alphen and Lodder, 2006). 1. It is well-established understanding that strong earthquakes often cause large numbers of landslides in mountainous areas. The magnitude of earthquake is measured by richter scale and intensity by mercalli scale( Table). The Japanese Geotechnical Society . Jan 24, 2024 · Evidence from recent earthquakes has shown destructive consequences of fault-induced permanent ground movement on structures. Keywords Earthquake induced pounding · Adjacent buildings · Mitigation measures · Separation · Expansion joint · Rubber shock absorber · Seismic performance · Time history analysis S. A destructive earthquake struck the Kobe region on January 17, 1995, and a massive earthquake and tsunami struck eastern Japan on March 11, 2011. 3 Earthquake-Resistant Design and Construction of New Structures. To describe different activities involved in earthquake risk mitigation/ preparedness including building codes; 3. GOAL 3: Improve the earthquake resilience of communities nationwide. Examples: building codes and zoning; vulnerability analyses; public education. Earthquake and tsunami disasters have been increasing rapidly and globally in the last quarter-century. These enormous waves cause extensive and widespread destruction funds for mitigation and preparedness measures and review the developmental plans of the different departments of the State to ensure integration of prevention, preparedness and mitigation measures. fema.
