Why do I care. Earthquake. – shaking and trebling that results from the movement of rock beneath Earth’s surface.. Plate movement causes earthquakes from stress and faults in Earth’s crust. When the rock breaks earthquakes happen. November 2012 Istanbul, Turkey. C. . Neagoe. , L.M. . Manea. and C. Ionescu. National Institute for Earth Physics, . Magurele-Ilfov. , Romania. . In . February 1977, the Department of Seismology from the Romanian Geophysical and Geological Institute (GGI) together with the Laboratory of Geodynamics of the Romanian Academy formed the Centre of the Earth Physics (CEP). In 1994, after a governmental decision, CEP was transformed in the National Institute for Earth Physics (NIEP). NIEP is coordinated by the Romanian Ministry of Education, Research, Youth and Sport. . 3D seismic reflection image of the . Nankai. Subduction zone, Japan. Seismic Sources: Land Surveys.

An earthquake (also known as a quake, . tremor) . is the . shaking of the surface. of the Earth, resulting from the sudden release of energy in the Earth's lithosphere that creates seismic waves. . Core Contractors are your trustworthy team of Seismic Retrofit Contractors Los Angeles and surrounding areas that comply with the Los Angeles retrofit requirements and other municipalities in the retrofitting of buildings just like yours. Earthquake Mechanisms. Brittle Mechanical Model: “stick-slip”. Focal point: 3D point inside the lithosphere where the seismic event occurs. Epicenter: projection of focal point to the map surface .
