IUGG XXIV General Assembly July 2-13, 2007 Perugia, Italy<br />

Interior<br />

JSS003 1845 - 1892<br />

Symposium<br />

Early-Warning Systems<br />

Convener : Prof. Jochen Zschau<br />

Early warning systems can reduce the negative impacts across the globe of extreme events such as<br />

earthquakes, tsunamis, volcano eruptions, landslides, tropical storms, floods, extreme space weather<br />

and others. They provide timely information that allows individuals exposed to a hazard, to take action<br />

to avoid or reduce their risk and prepare for effective response. Dependent on the type of hazard the<br />

warning time available may range between only a few seconds in case of earthquakes to months and<br />

years in case of creeping disasters such as droughts. Although rapid information- and early warning<br />

technologies are now available to a great extent, their potential in the field of disaster mitigation is not<br />

used to any appreciable extent, showing that the user needs are not yet addressed sufficiently.<br />

Integrated earth observation, the development of real-time analysis, modelling and simulation methods,<br />

their integration with appropriate facilities for data processing, visualization and rapid information<br />

systems and their application to early warning in conjunction with disaster management, therefore,<br />

remains one of the major challenges of applied earth system sciences. The session will discuss the latest<br />

scientific/technological developments, projects, programs and best practices in the field of early<br />

warning. This will be done for various disaster types, from global to local scale and with special regard<br />

to the user needs. Contributions are particularly welcome if they address the aspect of multi-hazard<br />

early warning.
