Abstract

Most of Tsunami Early Warning System has used earthquake magnitude as indicator of tsunami. However, magnitude is not good indicator for Tsunami-genic Earthquake. Purpose of this study is to test the validity of Joko Tingkir computer program for decision-making on a tsunami early warning system in real time. The Joko Tingkir computer program implemented a Tsunami Faulting Model (TFM). TFM uses the principle that the tsunami affected by the length and width of earthquake rupture. Both can be represented by the duration of rupture (Tdur) or Exceed 50 second duration (T50Ex) and the dominant period (Td). TFM has been implemented by Joko Tingkir computer program. Based on the test results of Joko Tingkir computer programs in real time for 146 earthquakes (magnitude 5 to 6.9) and offline testing at FMIPA UNESA laboratory for 33 earthquakes (magnitude 6.5 to 9.3) can be concluded that the Joko Tingkir computer program can estimate Tdur, T50Ex and Td simultaneously, accurately and quickly, so the Joko Tingkir computer program can be used for decision making on real time Tsunami Early Warning System.
