Thamrin no 8, Jakarta 10340, Indonesia 6IRD, R 163, LMV, F-63038 Clermont-Ferrand, France *Corresponding author (e-mail: [email protected]) Abstract: Numerical modelling of a rapid, partial destabilization of Anak Krakatau Volcano (Indonesia) was performed in order to investigate the tsunami triggered by this event. Anak Krakatau, which is largely built on the steep NE wall of the 1883 Krakatau eruption caldera, is active on its SW side (towards the 1883 caldera), which makes the edifice quite unstable. A hypothetical 0.280 km3 flank collapse directed southwestwards would trigger an initial wave 43 m in height that would reach the islands of Sertung, Panjang and Rakata in less than 1 min, with amplitudes from 15 to 30 m. These waves would be potentially dangerous for the many small tourist boats circulating in, and around, the Krakatau Archipelago. The waves would then propagate in a radial manner from the impact region and across the Sunda Strait, at an average speed of 80–110 km h21. -

Impact of the December 2018 volcano-triggered tsunami in Krakatau complex on the coastal geomorphology and the buildings of the Sunda Strait (Indonesia) Efthymios Lekkas (1), Spyridon Mavroulis (1), Marilia Gogou (1), Panayotis Carydis (2), and Dimitrios Milios (1) (1) National and Kapodistrian University of Athens, Faculty of Geology and Geoenvironment, Department of Dynamic Tectonic Applied Geology, Athens, Greece ([email protected]), (2) National Technical University of Athens, Greece On December 22, 2018, a tsunami was generated near the Krakatau volcano complex in Sunda Strait between the Western Java and the Southern Sumatra (Indonesia). It is attributed to the collapse of the flank of the Anak Krakatau volcano, especially in its southern and southwestern sectors. The volcano-triggered tsunami devastated the coastal areas of western Java and southern Sumatra, and in particular Banten Province and Lampung Province respectively. It caused 437 fatalities and about 14059 injured people mainly attributed to the tsunami generation during the night and to absence of early tsunami warning. The tsunami arrived at the coastal areas of western Java and southern Sumatra in 24 to 37 minutes after the eruption of Anak Krakatau occurred at 21:03 of December 22 and with heights varying from almost 1 to 6 m based on recordings of tidal stations, eyewitnesses and tsunami marks on structures and vegetation. The research team of the University of Athens visited the worst tsunami-affected areas shortly after the disaster aiming to investigate the impact on the natural and built coastal environment. -

Economic Valuation for Cidanau Watershed Area, Indonesia
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Scientific Journals of Bogor Agricultural University JMHT Vol. XVI, (1): 27–35, April 2010 Artikel Ilmiah ISSN: 2087-0469 Economic Valuation for Cidanau Watershed Area, Indonesia Kunihiko Yoshino1*, Budi Indra Setiawan2, and Hideki Furuya3 1 Graduate School of Information and Systems Engineering, University of Tsukuba, Japan 2 Department of Civil & Environmental Engineering, Bogor Agricultural University, Indonesia 3 Department of International Tourism, Faculty of Regional Development Studies, Toyo University, Japan Abstract The paper describes economic valuation for the Cidanau watershed area of West Java in Indonesia. In this area natural resources deterioration has occurred even faster after the Asian Financial Crisis. The deforestation area and pronounced soil erosion seems to go unhindered because of land use competition among the residents for agricultural space, housing, etc. In order to prevent the area from further degradation, the purpose of this paper is to carry out quantitative evaluation which also attempts to raise the environmental awareness of residents, as well as visitors to the area. Questionnaire surveys were conducted and analyzed according to the Contingent Valuation Method (CVM) and the Travel Cost Method (TCM). The results show all respondents held good attitudes towards the efforts of environmental conservation, but responded negatively if they had to contribute to the environmental service payment. Visitors to the Anyer Beach acted differently because most of them come from faraway locations and have little knowledge of the watershed. However, the Anyer Beach recorded an environmental valuation of about Rp840 billion, which is a potential source for the service payment of Cidanau watershed. -
The Seafloor Morphologhy of Sunda Strait for Laying the Underwater Cables
THE SEAFLOOR MORPHOLOGHY OF SUNDA STRAIT FOR LAYING THE UNDERWATER CABLES By: Yogi Noviadi1 (Manuscript received 24-July-2010) ABSTRACT The coastal and offshore areas around the Sunda Strait will be developed to be a submarine cable corridor connecting between Java and Sumatra Islands. There are some requirements that should be considered before laying the underwater cables. One of these considerations is to understand the seafloor morphology of the Sunda Strait. The study was conducted based on six of track lines with 1 km line spacing and 4 Cross lines. The water depth obtained then was corrected to the depth of water from the Lowest Water Level (LWL). The seabed condition in the near shore area of Sumatra side is very flat and is influenced by 2 km offshore tide activity. The coast line is characterized by mangrove and fine fraction of sediments (mud and clay). At the Java side, the coastal morphology is characterized by the very steep slope and most of the area is occupied by the industrial activities. Keywords: seafloor morphology, under water cables, Sunda Strait SARI Area pantai dan perairan Selat Sunda akan dikembangkan sebagai bagian dalam penempatan kabel bawah laut yang menghubungkan Pulau Jawa dan Pulau Sumatera. Rencana penempatan kabel bawah laut ini membutuhkan beberapa persyaratan teknis yang harus dipertimbangkan. Salah satu pertimbangan untuk peletakan kabel bawah laut adalah memahami morfologi dasar laut selat Sunda. Penelitian dilakukan berdasarkan 6 lintasan pemeruman dengan jarak antar lintasan 1 km, dan 4 lintasan memotong lintasan utama. Kedalaman laut yang diperoleh kemudian dikoreksi dengan muka laut terendah. Kondisi permukaan dasar laut di sisi pantai Sumatra sangat datar serta sejauh 2 km ke arah laut lepas masih dipengaruhi oleh aktifitas pasang surut. -
