FORECASTING EARTHQUAKES
Title  The united science of seismology

The furies of the Earth can be awesome. Of the many destructive natural risks that humanity must face, earthquakes are perhaps the cruellest, due to the sudden and unpredictable nature of the violence they unleash. Although they are largely concentrated in known risk areas, there are a great many of them and some remain deceptively dormant for long periods. Paraseismic engineering techniques used in building construction are an important weapon against the destructive force of earthquakes. This protection saves many lives in the world’s more developed regions which can afford to build in this way. Elsewhere, earthquakes continue to sow death and destruction. What can science do in the face of such cataclysms unleashed from the very depths of the Earth?

The first step is to know and understand the phenomenon. Seismology and volcanology are new disciplines. Formulated as an uncertain hypothesis in the first half of the 20th century, plate tectonics has only come into its own as a science in the past 40 years. Thanks to geophysical and geological research, the study of data transmitted by a worldwide network of hundreds of thousands of sensors, satellite observation, and the detailed analysis of every earthquake of any importance, a vast body of knowledge is gradually being built up.

Is it possible that science will, one day, achieve the ideal objective of forecasting earthquakes? Natural disasters are essentially random. It would seem presumptuous to expect researchers to become reliable forecasters of such events, even if, on some occasions, this has already proved possible. We are exposed to an array of natural and human-induced environmental risks. Science can be a means of ‘taming’ them to limit the damage they cause, but not of eradicating them.

Due to the extreme fear they instil, no doubt more than any other natural disaster, earthquakes have always aroused strong emotions and given rise to powerful expressions of international solidarity. Seismology is a science that is particularly oblivious to national borders. It is a field in which Europe contributes knowledge and expertise of the very highest level to the international effort to understand this devastating phenomenon. 

Earthquakes are the subject of many Union-backed research projects. Usually carried out by multidisciplinary teams, they look at various aspects of the phenomenon, such as prediction, scenarios, monitoring systems and architecture.

Current European projects

Lessloss – Risk mitigation for earthquakes and landslides

A multidisciplinary project covering geophysics, geotechnical and paraseismic engineering, town planning, civil protection, the socio-economic sciences, and information and communication technologies.
