Course Title IEQ-05 : Earthquake Geology and Geoinformatics (Dept. of Earthquake Engineering‚ IIT Roorkee) What is an earthquake? An earthquake is the vibration of the earth produced by the quick release of energy. Most often‚ earthquakes are caused by movement along large fractures in the earth’s crust. Such fractures are called faults. The energy that is released radiates in all directions from its origin in the form of waves. These waves are similar to the waves that occur when you drop a

Earthquake Assignment Week 3 Earthquake Assignment Earthquakes Have you ever got so mad you have to squeeze something to release your pressure? Or maybe you walk around aimlessly taking deep breaths to try and discharge the stress something or someone caused. Our earth‚ too‚ has a way of releasing pressure. Earthquakes are the result of the earth’s crust letting go of its strain and stress. Earthquakes can be defined as a sudden and violent shaking of the ground resulting when the

Earthquakes Geography project Done by: DESHER TROTMAN Introduction Definition: An earthquake is a sudden tremor or movement of the earth’s crust‚ which originates naturally at or below the Earth’s surface. They can occur from fault lines where tectonic plates meet or from volcanic activity. Earthquakes are very common in areas of volcanic activity where they either proceed or accompany eruptions. Earthquakes caused by volcanic eruptions are rare since all volcanoes are not prone to violent

It occurred at 11:56 NST on 25 April‚ with a magnitude of 7.8Mw[1] or 8.1Ms[2] and a maximum Mercalli Intensity of IX (Violent). Its epicenter was east of the district of Lamjung‚ and its hypocenter was at a depth of approximately 15 km (9.3 mi).[1] It was the worst natural disaster to strike Nepal since the 1934 Nepal–Bihar earthquake.[10][11][12]

Kobe Earthquake An earthquake occurred on January 17th‚ 1995‚ at 5:46 am in the south-central part of Japan. This earthquake registered as 7.2 on the Richter scale and caused mass destruction. It was thus named The Great Hanshin Earthquake. It later earned the name as the Kobe Earthquake due to the amount of damage that Kobe‚ Japan suffered. Its focus was only 16 km below ground. Shock-waves splintered buildings‚ destroyed roads‚ and ruptured mains of gas‚ water‚ and electricity. Over 6‚400 people
