Understanding and living with the Earth

Geological information is essential for a country like Japan, located at a tectonically active area, to ensure a safe and secure society. The Geological Survey of Japan gathers, compiles, and provides geological information and promotes its wider use. We also develop technologies to overcome various difficulties related to global environment protection, exploration of minerals and energy resources, and natural disaster mitigation, and coordinate international cooperation as a national representative.

Complete Revision of the Web-Based Geological Map of Japan

AIST has completely revised the 1:200,000 Seamless Geological Map of Japan that seamlessly shows geological information on all regions of Japan and has been available for viewing on our website since 2005. As the rocks and strata classification principle has changed, the legends were revised based on the latest geological knowledge. The number of legends has increased to more than 2400, and more detailed information can be shown on the map. The new legends have been systematized and structured hierarchically. As a result, the way in which the geological map is displayed can be changed to suit a purpose or use.

Completion of the Eastern Asia Earthquake and Volcanic Hazards Information Map

AIST has created the “Eastern Asia Earthquake and Volcanic Hazards Information Map”. The map summarizes past disaster information on large-scale earthquakes, volcanic eruptions and the tsunamis that they triggered. Displaying the disaster scale, and the number and causes of fatalities on the map in icons enable the viewers to have a good grasp of the hazard situation. The map is expected to raise risk management awareness in East Asia. It can be used as basic data for disaster mitigation planning and hazard map creation. The map in image format has been made public on the Geological Survey of Japan website.
