(3) Preparation of the Coastal Disaster Prevention Informational Chart
JMSA has prepared the Coastal Disaster Prevention Informational Charts, which on one chart provides comprehensively the information required when an earthquake, tsunami, or other natural disaster occurs, in order to carry out quick and appropriate maritime rescue and relief activities in the event of such natural disasters. JMSA distributes these charts to disaster prevention related agencies. In FY 1996, in addition to the Kanto, Tokai, and Kagoshima regions, it has also been investigating Osaka Bay and the coastal areas of the Kii Channel which are near the Median Tectonic Line, one of Japan's largest faults.
Hereafter, JMSA will continue to proceed to prepare similar charts for regions nationwide with a high probability of natural disaster occurrence.
(4) Conducting Disaster Fighting Drill
JMSA has been conducting disaster fighting drills jointly with local public bodies and related organizations. These drills include the assembling of personnel, transmission of d they are devised information, maritime rescues, fire-fighting, and combating oil spills, an to accommodate the peculiarities of the respective regions.
3. Disaster Prevention Studies
(1) Participation in the Earthquake Prediction Plan
The Geodesic Council of the Ministry of Education proposed the First Earthquake Prediction Plan in 1964. At present, the 7th Plan (FY 1994 - 98) is being implemented. In accordance with this plan, related organizations are conducting studies and research related to earthquake prediction.
The results obtained through these activities are reported to the Earthquake Research Committee of the Headquarters of Earthquake Research Promotion and Coordination Committee for Earthquake Prediction. In addition to being the basic data for understanding the mechanism for the occurrence of earthquakes, which include data pertaining to the distribution and nature of faults in sea areas and stress on the earth's crust, JMSA publishes " "Submarine Geological Structural Charts, "this data in the form of the "Bathymetric Charts, "Magnetic Anomaly Charts," and "Gravity Anomaly Charts."
(2) Participation in the Volcanic Eruption Prediction Plan
The Geodetic Survey Council proposed the Volcanic Eruption Prediction Plan in 1973. At present, the Fifth Volcanic Eruption Prediction Plan (FY 1994-98) is being implemented.
JMSA has participated in this endeavor from the First Volcanic Eruption Prediction
