6 Maximum Intensity Historical record ~1500 years ago MM is about X in Northern Part Instrumental Record 1935 Ml 6.5 in Northern Part 1983 Ml 5.9 in Western Part

7 Development of seismic network in Thailand WWSSN were set up in Chiangmai and Songkhla Analog Stations (SP 1Hz) Digital Stations (2 SP 3BB) Digital Stations from 2 phase installation First phase primary stations consist of 7 (Trillium120),8(Trillium 120),15 (TSA110) Second Phase consist of 15 (S-13),10(KS-2000M),25(PA23),1(KS2000BH),2(PA23BH)

10 Thai National Seismic Monitoring Network Primary Stations Phase 1(15 STA) Phase II(25 Sta) -Seismometer,Accelerometers,Data Logger,Communication link in real time(vsat,ipstar,adsl) Stand alone Accelerograph stations(26 sta) 2 Bore hole Stations at TMD in Bangkok Seismic Monitoring Center at Seismological Bureau,Thai Meteorological Department, automatic EQ determination software

11 Backup system More stations, several transmission data channels (IP star, ADSL,VSAT) 2 internet providers 2 acquisition servers, 2 Graphic user interface servers,3 automatic EQ Determination software(earlybird,smartquake,seiscomp3) 3-4 Fax machines 2 UPS+Diesel Electricity generator

12 AFTER 2004 Tsunami ADSL IPSTAR TMD Seismic Network 15 Automatic Seismic stations are operated at present. Plus 25 station will operate in 2008 (Red Triangles) ADSL IPSTAR ADSL

33 Regional Earthquakes can be determined by Thai Seismic Monitoring Network Andaman,Sumatra,Indian Ocean (~5-10 Mins) Southwest Pacific,South China Sea, Phillipines,Papua New Guinea,Tonga (~5-12 Mins) Australia,New Zealand (~15-18 Mins) Neigbouring countries: Indonesia,Malaysia,Myanmar,Laos Vietnam, S China,(~3-12 Mins) North and South America (~20 Mins)

34 Phase II 25 seismic stations (10BB,15 SP) 20 Acceleration stations 2 Borehole stations 4 GPS stations 9 Tide Gauge stations Project will finish in 2009

36 Tide Gauge Station at Ranod Songkhla

37 Research work in seismology and Earthquake Engineering,Tsunami Data base compilation of earthquake data and Tsunami -Historical data and instrumental data plus focal mechanism compilation -Trenching Fault in the northern and western part -Dynamic response of building response in Bangkok -Micro tremor analysis in Bangkok area -Paleotsunagenic Research in the southern part

38 Strategy to face with TSUNAMI More Sharing RT Data and significant information Seismic data, Earthquake information, warning message,tide Level and Bouy data More capacity building By various assistance from organization :USAID,GFZ,USGS,IOC,IRIS,CEA etc. More knowledgement public would know well what and how to do when natural disaster occurs.

39 Conclusion Progress for rapid EQ determination Ability of sharing EQ data in RT More cooperation with agencies networks regarding to EQ and Tsunami Need more developmet for tsunami early warning system i.e. tsunami modeling, inundation, SOP, dissemination etc
