Here is my first oral presentation in an International Conference in Japan!

Asian Seismological Commission Fall meeting 2008, held in Tsukuba.


With prelimanary result, trying to get some idea from the attendees..

Big Thanks to my supervisors for the chance, all help and discussion. Thanks to Endra and children for their big understanding in the emergency time, Asahi San for all practices we`ve done together.

One surpriseing notice in this conference is that there is a tentative nursuring! Though quiet expensive (500 Yen/Child/Hour) but it`s already student price and very helpful!

In this chance I present my preliminary work of the Java 2006 Tsunami modeling. The Java 2006 Tsunami occured at 17 July 2006, 1.5 year after the giant Sumatera 2004 Earthquake Tsunami. After the tragedy, many peopl especially along the coast were frightened of the Tsunami. Government annouce that only Earthquake with magnitude more than 7 would triggered Tsunami.

On July 17, 2006, a small earthquake of Magnitude 6.8 (BMG) occured in the south coast of Pangandaran, in the trench of South of Java, with very slight shaking. BMG than annouced no danger of tsunami because of its low magnitude. But 45 minute after, a tsunami of 3-8 meter height inundated Pandangaran coast! It was veryy veryy contractictive event, and make many people confused and frightened.

This Java 2006 event was then considered as Tsunami Earthquake Event, due to its low magnitude but hight tsunami wave generation. Tsunami Earthquake are very rare event in the world. less than 10 event in this last century were recorded as tsunami eartquake. One interesting thing here is that previously, there were also a tsunami earthquake in the trench of South of East Java, that also inundated Banyuwangi – East Java about 3-8 m height. It raise question about how is actually the geodynamic in Java Trench? I am trying to answer this in my phd research.
