Java
(Sunda) trench lying along the eastern and southern coasts of Indonesia is one
of the world's most active seismic zone. Java (Sunda) trench experienced
devastating earthquakes and tsunamis throughout history. Despite the fact
that about 14 years have passed since the 2004 Indian Ocean earthquake and
tsunami, the seismic activity in this region is still intense. Thus, reliable
estimation of the associated hazard of a possible large earthquake that can
generate tsunami is vital for designing early warning systems, site selection
of future critical infrastructures (CIs) and planning necessary mitigation
measures for existing CIs and critical regions (CRs). Therefore, Scenario-based
Tsunami Hazard Assessment (STHA) is performed for this region in this study.
Historical earthquake data is compiled using the ISC-GEM Global Instrumental
Earthquake Catalogue for the region. Monte Carlo (MC) simulation method is used
to generate random earthquake source parameters (i.e. magnitude, focal depth)
along Java (Sunda) trench. The worst-case scenario among MC runs is selected
and simulated using NAMI-DANCE tsunami simulation software. Critical Regions
(CRs) and Critical Infrastructures (CIs) are identified and spatial
distribution of the inundation levels along the eastern and southern coastline
of Sumatra and Java Islands, focusing on these CRs and CIs is determined. It is
observed that some of the CRs and CIs are vulnerable to potential high-risk
tsunamis.

Monte Carlo Simülasyonu Kullanılarak Java (Sunda) Fay Hattı için Senaryo Bazlı Tsunami Tehlike Analizi
Öz
Endonezya’nın
doğu ve güney kıyıları boyunca uzanan Java (Sunda) fay hattı dünyadaki en aktif
sismik alanlardan biridir. Tarih boyunca Java (Sunda) fayında yıkıcı depremler
ve tsunamiler oluşmuştur. 2004 Hint Okyanusu depremi ve tsunamisinin üzerinden
14 yıl geçmiş olmasına rağmen bu bölgedeki sismik aktivite hala yoğun bir
şekilde devam etmektedir. Erken uyarı sistemlerinin yerleştirilmesi,
gelecekteki yapıların lokasyonlarının belirlenmesi ve mevcut kritik yapılar ve
bölgeler için risk azaltıcı önlemlerin alınması gibi konular için güvenilir bir
tsunami tehlike analizi yapılması hayati önem taşımaktadır. Bu kriterler göz
önüne alınarak bu çalışmada senaryo bazlı tsunami tehlike analizi (STHA)
çalışılmıştır. Tarihsel deprem verisi ISC-GEM Küresel Deprem Kataloğundan
derlenmiştir. Java (Sunda) fayı boyunca rastgele deprem verisi (magnitüt ve
fokal derinlik) üretmek için Monte Carlo (MC) simulasyonu kullanılmıştır.
Üretilen veriden en kötü senaryo seçilmiş ve NAMI-DANCE yazılımı kullanılarak
tsunami simulasyonu yapılmıştır. Belirli kritik bölgeler ve altyapılar için
tsunami dalga yükseklikleri belirlenmiş ve su altında kalan bölgeler ArcGIS
programı kullanılarak gösterilmiştir. Bazı kritik bölge ve altyapıların yüksek
seviyede risk potansiyeli taşıdığı belirlenmiştir.
