Sunardi's Site

A research of tsunami generated by the October 25th 2010 earthquake at Mentawai Western of Sumatra has been investigated. The observation of tsunami run up is about 5.7-7.4 m at three locations in the South and North Pagai. Numerical simulation of tsunami using the source mechanism obtained from BMKG results 3.8 m of tsunami wave height, while the propagation model shows that tsunami reach Enggano and Padang for about 38 and 58 minutes close to the tsunami travel time observation. It is clearly...

The establishment of the tsunami warning system is based on the fact, that the seismic waves propagate faster then tsunami wave. The tsunami wave arrive in the shore line after the earthquake parameters can be determined, so that there is time left to evaluate the earthquake, whether the earthquake is tsunamigenic or not, disseminated the information or warning to the target area, and finally to do evacuation if necessary. For the tele-tsunami, in which the tsunami will arrive in the beach more...

A mid-term precursory seismic rate changes before 2007 Bengkulu earthquake and 2009 Padang earthquake was observed. We focused in this study on analyze seismotectonic parameter and seismic rate changes over Sumatra using Matlab. Seismicity rate changes parameter is used to identify mid-term precursor. We use the catalogue of USGS and BMKG from 1973.03 up to 2009.69. From seismicity rate changes anomaly, earthquake precursor can be identified 3-1 years before M8.5-M7.9 (USGS) 13 September 2007...
