CONTENTS OVERVIEW SRI LANKAN SEISMIC NETWORK SOUTH EAST SEISMIC STATION SPECIFICATIONS: SENSORS/LOGGER/SOFTWARE

Overview There was no seismic network system for Sri Lanka before 2005 However, a single seismic station was established in 1996 under the Global Seismic Network (GSN) at Pallekale, Kandy First Sri Lankan Seismic Network has established in June, 2005 funded by the Japanese Government (JICA)

1)Detect a domestic earthquake and calculate Epicenter and Magnitude 2)Post processing function 3) Data communication: Telephone Line (Dial up) (To reduce the running cost) 4) Four Seismic Stations (To calculate Epicenter) Initial Plan of establishing this seismic network include :

SRI LANKAN SEISMIC NETWORK June, 2005 Funded by JICA There are four seismic stations were established under this network at four universities. Local station(RHN) Ruhuna Univ. Local station(RJR) Rajarata Univ. Central Station (PRD) Peradeniya Univ. Local station(EST) South-East Univ.

Overview (Function) 1)Continuous Data recording (6ch, one month) 6ch: Acceleration 3ch, Velocity 3ch 2)Automatic Trigger Function and Call to Central Station (Peradeniya) 3) Automatic Data correction from Central Station to Local Station (Manual correction is also Available) 4) Automatic Processing Function (SEISAN) Epicenter(Domestic), Magnitude 5) Post Processing Function (SEISAN)

Software for Central Station Data Collection from each stations Data Storage Data Analysis *Epicenter *Magnitude *Spectrum etc Maintenance (Each station ) Telephone Line Data Logger (6ch) with GPS Personal Computer Hub Printer U P S Modem TCP/IP Protocol Converter Router Concrete Base Outside Inside Central Station (Peradeniya) UNIV.
