THE SEISMOLOGICAL NETWORK AND EARTHQUAKE ACTIVITY IN VIETNAM Dinh Quoc Van, Institute of Geophysics, Vietnam Academy of Science and Technology
Overview 1. The Vietnam seismological network; 2. The eathquake activity in Vietnam.
The Vietnam National Seismological network
- The permanent seismic station (12) - Vietnam station: 5 - Jamstec station: 3 - ADPC station: 2 - TW station: 2 - The temporary seismic station (45) - Vietnam station: 15 - TW station: 25 - Poland : 5 - Online station (21) - Permanent stations: 12 - Temporary stations: 9
The near futureVietnam national seismological network (project for 2009-2016) - 28 permanent stations, with: 10 Q330HRS/Q330HR/STS-2.5 (120s)/Epi-sensor 18 Q330HR/Metrozet PBB200 (40s)/Epi-sensor - 12 temporary stations with: 12 Guralp CMG-6TD (30s-100Hz)
The extension Vietnam national seismological network project (2012-2017) - 36 stations, including 6 stations in Ho Chi Minh city and vicinity
The Local seismic network
The Song Tranh 2 dam located in the centre of Vietnam (Quangnam province) 190 mW, include two machines Reservoir capacity: 740 million cubic meters of water
The Song Tranh 2 seismic network (10 stations, August, 2013) Broadband stations Short-period stations The Song Tranh 2 seismic network (10 stations, August, 2013) - Five Vietnam seismic stations (broadband 30s) - Five Poland seismic stations (Short-period 1s) - Online network
The Local seismic network for monitoring trigger seismicity in Lai Chau reservoir for project 2014-2018
