摘要

When the large-scale disaster occurs, disseminating usefulinformation such as damage prediction, shelter, andtransportation information is necessary. This is useful forpreventing more damage and confusion of resident. OnDecember 26, 2004, a big earthquake, called 2004 IndianOcean earthquake, caused enormous damage to thecountries of Southeast Asia. The seismic center of it is offthe west coast of Sumatra, Indonesia and the shock had amoment magnitude of 9.1–9.3. The tsunami hit in 14countries such as Indonesia, Sri Lanka, Thailand, etc., andmore than 200,000 people were killed. Patong beach(Patong Municipality) in Phuket, Thailand is one of theareas greatly affected by the tsunami [1][2]. The biggestreason why the damage of the tsunami was enormous inthat area is that almost all residents, tourists and localorganization lacked knowledge of disaster responsesbecause the occurrence of a disaster such as an earthquakeor tsunami was very rare. Since that time, the residents andrelated organization have noticed the importance ofsurveillance of disasters and providing disaster-relatedinformation. Then, various kinds of technology for disastersurveillance and notification of disaster-related informationhave been developed. Therefore, currently there are manymethods to provide useful information by disaster warningtowers, which are installed in 3 points along the Patongbeach, car speaker and fax. However, it is difficult toaccess abundant disaster-related information on theInternet directly. By the way, we interviewed residents andlocal organization in Patong beach area as part of thepreliminary survey. In the interview, the comments suchthat the way which can access disaster information directlyis better than the current system were obtained.
