National Earthquake Monitoring for Tsunami Early Warning Burin Wechbunthung Sumalee Prachaub Seismological Bureau, Thai Meteorological Department
Seismic Sources Out line Historical Earthquake Damage from Earthquake Seismic Monitoring Network -Stations,sensors,link,data processing,analysis,desemination Capacity of epicenter determination
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
Development of seismic network in Thailand 1963-1965 2 WWSSN were set up in Chiangmai and Songkhla 1975-1997 14 Analog Stations (SP 1Hz) 1998-2008 5 Digital Stations (2 SP 3BB) 2006-2008 40 Digital Stations from 2 phase installation First phase 2004-2006 primary stations consist of 7 (Trillium120),8(Trillium 120),15 (TSA110) Second Phase 2007-2009 consist of 15 (S-13),10(KS-2000M),25(PA23),1(KS2000BH),2(PA23BH)
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

Research work in seismology and Earthquake Engineering,Tsunami Data base compilation of earthquake data and Tsunami -Historical data and instrumental data 1900-2002 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
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.
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
