Abstract

Damages during earthquakes are mostly confined to few tens of kilometer radiuses from epicenter and are located within the highest Intensity Isoseismal. In addition to this it has been seen that the Long Period Surface Waves cause heavy damage to tall structures (height > 17 m). Such damages have been observed during Mexican Earthquake of 1985, Bhuj Earthquake (India) of 2001 and Pakistan Earthquake of 2005. The destruction had occurred at 520, 310 and 150 km distance from the epicenters of the above three earthquakes. The damage is accentuated if the structures happen to be located on the filled land. With increasing urban expansion a number of cities are now becoming seismically vulnerable.

Damage to Tall Structures Situated at Long Distance from Epicenter Due to Long Period Seismic Waves and Effect on Structures on Filled Lands

Arlington, Virginia

Damages during earthquakes are mostly confined to few tens of kilometer radiuses from epicenter and are located within the highest Intensity Isoseismal. In addition to this it has been seen that the Long Period Surface Waves cause heavy damage to tall structures (height > 17 m). Such damages have been observed during Mexican Earthquake of 1985, Bhuj Earthquake (India) of 2001 and Pakistan Earthquake of 2005. The destruction had occurred at 520, 310 and 150 km distance from the epicenters of the above three earthquakes. The damage is accentuated if the structures happen to be located on the filled land. With increasing urban expansion a number of cities are now becoming seismically vulnerable.
