CAUSES AND EFFECTS OF EARTHQUAKES‚ TSUNAMI AND CYCLONES EARTHQUAKES What are Earthquakes? ← An earthquake (also known as a quake‚ tremor or temblor) is the result of a sudden release of energy in the Earth’s crust that creates seismic waves. The seismicity or seismic activity of an area refers to the frequency‚ type and size of earthquakes experienced over a period of time. Earthquakes are measured with a seismometer; a device which also records is known as a seismograph. The moment

EARTHQUAKE An earthquake (also known as a tremor‚ temblor or seismic activity) is the result of a sudden release of energy in the earth’s crust that creates SEISMIC WAVES. Earthquakes are measured with a seismometer; a device which also records is known as a seismograph. SEISMIC DEFORMATION When an earthquake fault ruptures‚ it causes two types of deformation: static; and dynamic. Static deformation is the permanent displacement of the ground due to the event. The earthquake cycle progresses

Investigations of past and recent earthquake damage have illustrated that the building structures are vulnerable to severe damage and/or collapse during moderate to strong ground motion. Among the possible structural damages‚ seismic induced pounding has been commonly observed in several earthquakes. A parametric study on buildings pounding response as well as proper seismic hazard mitigation practice for adjacent buildings is carried out. Three categories of recorded earthquake excitation are used for input
