This task is carried out by BGR which operates a central archive and collection point for seismological parameter and waveform data from various German seismological facilities (seismological observatories, university institutes for geophysics, state geological surveys). But continuous seismic monitoring is imperative because of the dense population and major industry in this country. Germany has not been hit by catastrophic earthquakes so far, and such earthquakes are considered highly unlikely in the future because of the geological and tectonic conditions. More statistical information about earthquakes. On account of the increase in population densities and technical infrastructures, the losses generated by earthquakes are expected to continue to rise in the future. EUR 6 billion (Source: Munich Re-Insurance). The economic damage caused by these natural disasters in 2000 alone is estimated at more than EUR 310 million, and during the last 10 years, approx. Most of the earthquakes clearly occur along the plate boundaries Source: BGRĮarthquakes have resulted in the loss of more than 2 million human lives in this and the last century. The Earth showing the distribution of earthquakes (dots) covering a period of 50 years. Additional fields of activity are seismic risk analysis, seismic hazard assessment, seismic wave propagation, and investigations of the Earth’s structure.
The scope is as broad as the field of seismology itself, and ranges from the monitoring of seismicity in Germany and the rest of the world, to studies of earthquake source processes. In addition to politically related activities, BGR is involved in various scientific seismological projects. This is because data from seismic monitoring stations can be used to detect, locate and identify man-made events, such as nuclear weapon tests. It is not of sole importance to earth science - such as the source mechanisms of earthquakes, propagation of seismic waves and the structure of the Earth’s interior - but also of political significance. To collect information about ground shaking following significant earthquakes.Seismology - the science of earthquakes - covers a broad range of applications.
