Capability for Earthquake Monitoring

It had taken, at least, 20 minutes to identify the

location of epicenter and size of magnitude

when using the old network.

Using the new network (2005-2008), less than

5-10 minutes is expected to complete

preliminary determination of an earthquake.

Warning Towers

Phase 1 (completed) :

76 towers installed in southern Thailand, west coast

Phase 2 (completed) :

48 towers installed in southern Thailand, east coast

Phase 3 :

144 towers will be installed in central, northern, & northeastern Thailand.

Aim : A complete network of 268 warning towers in 76 provinces of Thailand to transfer alarm signals for natural disaster warnings through a satellite orbit

Proposed Thailand’s Integrated Early Warning System for beaches, hotels, schools, buildings, boats, & cars etc.

TMD’s Telemetering Stations

TMD has been approved some other budget in the 2007 fiscal year for implementing the following projects :

Telemetering-related Project in 2007 - 2008

+ 2007 : Replacing voluntary rainfall stations in northern Thailand with telemetering stations (110 stations are designed for flood monitoring and warning covering critical flood risk areas.)

+ 2008 : Replacing volunteer rainfall stations over Thailand with telemetering stations (820 stations are currently designed to cover the whole country.)
