Active Faults Study of
Potential Great Earthquake in Sunda Arc
1
Introduction
• Western Java is the most dense population in Indonesia.
• Many infrastructures such as : Industries, Tourism, Public service facilities, etc.
• Western Java is predicted by scientists as one of the highest potential earthquake and tsunami hazard.
• Advance technology is needed to reduce the risk.

Research by BPPT : Preliminary result
MODELLING BY DR. WIDJO KONGKO
Tinggi tsunami di JSS sekitar 6 – 10
Untuk scenario M9
• Indonesia will be suffered and has big lost if the predicted EQ and tsunami occurred.
• We need to be well prepare and need good hazard mitigation and adaptation technology
• BPPT has very long collaboration with JAMSTEC > 20 years.
• DONET (Dense Ocean Network System for Earthquake and Tsunami) is one of the most advance technology.
• BPPT-JAMSTEC plan to implement this technology

DONET: Dense Oceanfloor Network System for Earthquakes and Tsunamis
(JAMSTEC, proposed for Southern West Java)
Benefit
22/12/2009 Footer 21
• Precise Earthquake epycentrum calculation
• Earthquake early detection.
• Well inform tsunami Early Warning
• Very good data for modelling and research activity
including earthquake prediction
• Expensive but safe and almost free maintenance
• Ina buoys are broken due to vandalism.
• Ina buoys technology is High cost maintenance and
operation
Other Factors • The best location to support infrastructure of
DONET (Electric Power Plan, transportation, safety, and man power).
• Use higher technology in the future which needs earthquake early detection :
– Jakarta Subway’s system.
– High building
– High risk Industry in Cilegon
– Evacuation of tourist at Charita
– Giant sea wall infrastructure and Sunda Strait Bridge. 22
