East Asia is a region of the world where the risk of natural disasters such as earthquakes, tsunamis and volcanic eruptions is very high. In a globalised economy such as ours, when a major disaster occurs, a series of unpredictable disorders can affect not only the region concerned, but also the rest of the world. The implementation of measures to prevent such disasters is essential for sustainable development. The authors of this paper are convinced that every effort should be made to develop an international framework to reduce the risks of seismic events, tsunamis and volcanic eruptions as much as possible. The earthquakes in Sumatra on 26 December 2004 and in Tohoku on 11 March 2011 clearly demonstrate the urgency of creating an information and knowledge system for exceptional natural hazards. The release of ash from the Icelandic volcano Eyjafjallajökull in April 2000 caused the cancellation of more than 20,000 commercial flights a day in Europe, resulting in the greatest disruption to air travel since World War II. The G-EVER (Asia Pacific Region Earthquake and Volcanic Eruption Risk Management) consortium promotes seismic and volcanic risk reduction activities through collaboration between different research institutes worldwide.
The Information map on seismic and volcanic risks in East Asia is the result of the collaboration of the G-EVER promotion team based at the Geological Survey of Japan, AIST, with other geological institutes in South and East Asian countries. The map includes a wealth of data on natural hazards in this region of the world, as well as geological and tectonic information: distribution of active faults, earthquake foci and source areas, active volcanoes, calderas, large-scale igneous and ash emissions, and the number of fatalities in major disasters resulting from volcanic eruptions, earthquakes and tsunamis. This work is accompanied by downloadable Explanatory Notes (English only) here.
The number of victims, in the case of earthquakes and volcanic eruptions, has been classified according to the main cause of death and formalised graphically in order to facilitate the reading of the magnitude of the damage resulting from these disasters. The map data can be viewed, consulted and downloaded from the G-EVER website http://ccop-geoinfo.org/G-EVER/.

"Eastern Asia Earthquake and Volcanic Hazards Information Map" is the first map compiled and published by the G-EVER Consortium. The aim of this document is to provide a powerful tool and an indispensable source of information for risk reduction policies.
