The establishment of the ASEAN Earthquake Information Center (AEIC) was endorsed by the 40th Meeting of the Committee on Science and Technology held in October 2000, at the request of the ASEAN Sub-Committee on Meteorology and Geophysics (SCMG) to obtain the ASEAN Standing Committee’s (ASC) approval to officially use the name “ASEAN Earthquake Information Center (AEIC)”. As part of AEIC activities, the SCMG implemented a project on the ASEAN Seismic Network for Rapid Exchange of Strong Earthquake Data (ASNET RESED). The project was implemented by the ASCMG with funding support from the Government of Japan through the Japan ASEAN Co-operation Promotion Program (JACPP). The aim of the project is to facilitate the rapid exchange of data and information on earthquakes with magnitudes greater than 5.5 on the Richter scale, and to link all of the ASEAN National Seismological Centers through the Internet to disseminate earthquake information. For the future program, we propose a seismic data exchange between the National Seismological Centers in ASEAN countries as well as world seismological centers using the facilities in the AEIC. The plan is basically to develop and update the software and hardware in the NSC and AEIC for data communication. To refresh our knowledge in seismology and data communication, we arrange the training sessions for both topics. 展开更多
