Function and task

- Managing, operating and developing National seismic network.

- Conducting basic and applied researches for fast and accurately collecting data.

- Researching characteristic of wave propagation and strong ground motion in Vietnam and adjacent area for studying deep structure and seismic hazard assessment.

Network system

Instruments

- 9 short period of 1s, 1 component sensors.

- 14 short period of 1s, 3 component sensors.

- 5 broadband sensors 120s-50Hz, going to add 20 sensors more.

Seismic networks

- Telemetry network for observing earthquake surround Hanoi and adjacent area.

- Short period network for observing earthquake in Vietnam and adjacent area. It is distributed on whole Vietnam, and mostly concentrate in Northern Vietnam.

- Broadband seismic network is in project ”Strengthening seismic network for earthquake information and tsunami warning in Vietnam”, including 25 broadband seismic stations. 5 stations have installed, the rest are going to be installed in coming time.

International cooperation

- Cooperating with Institute of Earth Sciences, Academia Sinica, Taiwan to deploy 25 broadband seismic stations for studying wave propagation characteristic, deep structure and seismic hazard assessment in Vietnam.

- Cooperating with National Central University, Taiwan for studying site effects in seismic hazard assessment.

- Cooperating with National Taiwan University in seismological research and education.

- Cooperating with University of Tokyo and Japan Agency for Marine-Earth Science and Technology (JAMSTEC) to deploy 3 broadband seismic stations for studying deep structure in Vietnam.

- Cooperating with Asian Disaster Preparedness Center (ADPC) and Regional Integrated Multi-Hazard Early Warning System (RIMES) to deploy 2 broadband seismic stations to exchange information in order for earthquake information and tsunami warning in Vietnam.
