Abstract
Earthquakes represent a major hazard for populations around the world, causing frequent loss of life,
human suffering and enormous damage to homes, other buildings and infrastructure. The Technology Resources for
Earthquake Monitoring and Response (TREMOR) Team of 36 space professionals analysed this problem over the
course of the International Space University Summer Session Program and published their recommendations in the form
of a report. The TREMOR Team proposes a series of space- and ground-based systems to provide improved capability
to manage earthquakes. The first proposed system is a prototype earthquake early-warning system that improves the
existing knowledge of earthquake precursors and addresses the potential of these phenomena. Thus, the system will
at first enable the definitive assessment of whether reliable earthquake early warning is possible through precursor
monitoring. Should the answer be affirmative, the system itself would then form the basis of an operational earlywarning
system. To achieve these goals, the authors propose a multi-variable approach in which the system will combine,
integrate and process precursor data from space- and ground-based seismic monitoring systems (already existing and
new proposed systems) and data from a variety of related sources (e.g. historical databases, space weather data, fault
maps). The second proposed system, the prototype earthquake simulation and response system, coordinates the main
components of the response phase to reduce the time delays of response operations, increase the level of precision
in the data collected, facilitate communication amongst teams, enhance rescue and aid capabilities and so forth. It is
based in part on an earthquake simulator that will provide pre-event (if early warning is proven feasible) and post-event
damage assessment and detailed data of the affected areas to corresponding disaster management actors by means of a
geographic information system (GIS) interface. This is coupled with proposed mobile satellite communication hubs to
provide links between response teams. Business- and policy-based implementation strategies for these proposals, such
as the establishment of a non-governmental organisation to develop and operate the systems, are included.
