  1. Seismological Observation And Network of BMD Md.Rubyet Kabir nobel_74@yahoo.com Seismic Observatory And Research Center Bangladesh Meteorological Department Bangladesh WWW.bmd.gov.bd

  2. Introduction Bangladesh Meteorological Department is the only responsible organization in Bangladesh for monitoring earthquake and Tsunami. This Presentationindicatesthe status of seismic monitoring, early warning communication systems and the data processing system of BMD.

  3. Seismic Network of BMD BMD’s seismic monitoring system nation-wide consists of four digital Broad-Band Seismometers, two Borehole, two digital short-period seismometers and six accelerometers with GPS Synchronization

  4. Seismicity (2007- Mar 2010)

  5. Diagram of Dhaka Seismic Center

  6. Diagram of Chittagong, Sylhet and Rangpur Seismic Stations

  7. Type of instrument • From April 2007 Broad Band seismometer, Short period seismometer, Borehole seismometer, Accelerometer etc are in operation. All of these seismometer have three components namely N-S, E-W, and vertical. • Also we have a GPS network.

  8. Type of Seismic Equipments Short period seismometer Broad band Seismometer Accelerometer Borehole Seismometer

  11. Seismic Communication System

  12. EARTHQUAKE ANALYSIS S=V.T Occurrence time: 08 53 02.34(UTC) Epicenter : Lat- 27.39N, Long- 091.37E Magnitude: 6.3 (R.S) Depth :10 Km, Distance: 462 km

  13. BMD Bulletins Dissemination Mechanism
