H. 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)

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. -

Thirty-three butterfly species were collected in July 1993 from Sebesi and Sebuku Islands, Indonesia. Most of them were identified at the subspecies level, except several lycaenids. Fourteen species (42.4%) out of the 33 have never been recorded from the Krakataus. This proportion is distinctly higher than 4 to 8 (13.3 to 26.7%) of 30 species recorded from Sebesi in 1989. When these data were taken together, the percentage becomes 32.7 to 40.4% (17 to 21 of 52 species recorded from Sebesi-Sebuku). Comparison between Javanese and Sumatran subspecies in the rate of commonspecies on Sebesi-Sebuku and the Krakataus indicates that the butterfly fauna of the Krakataus have been chiefly derived from Java rather than from Sumatra even though the 2 stepping-stone islands exist between the Krakataus and Sumatra. -

FEDERALISM, ETHNIC POLITICS and VIOLENT CONFLICT Molly
ABSTRACT Title of dissertation: WHEN NATIONAL MINORITIES BECOME LOCAL MAJORITIES: FEDERALISM, ETHNIC POLITICS AND VIOLENT CONFLICT Molly Inman, Doctor of Philosophy, 2013 Dissertation directed by: Johanna K. Birnir Department of Government and Politics What explains the variation in ethnic conflict in federal systems? Existing theory and empirical evidence are mixed, with some saying it decreases violence, and some saying increases it. This puzzle also leads to a number of research questions: why does federalism fail to resolve the problem of violent ethnic conflict? Why does local ethnic politics in federal units frequently lead to violence within the ethnic group? What effect does federalism have on violence between ethnic groups? Why do central governments intervene with force into local interethnic conflicts rather than simply allowing the local government of the federal unit to resolve the issue? Conversely, why does federalism sometimes work in preventing violent conflict and session in countries where ethnic politics is salient? The theory presented here asserts that the level of intraethnic political compe- tition within the national minority/local majority and the political incentives created by devolving power to the local level determine the answers. I develop a new theory of local ethnic outbidding by minority groups in federal systems which explains how local ethnic politics turns violent when intraethnic political competition is high. Previous theories have focused almost exclusively on national level politics and vi- olence and have largely ignored the subnational level. I also explain how central governments become involved in local ethnic conflicts in federal systems, because local minorities being targeted call upon them for assistance. -
Analysis of Tourism Mapping in Lampung Province to Optimize Entrepreneurship Development
Review of Integrative Business and Economics Research, Vol. 8, Supplementary Issue 2 110 Analysis of Tourism Mapping in Lampung Province to Optimize Entrepreneurship Development Khomsahrial Romli* Universitas Bandar Lampung M. Oktaviannur Universitas Bandar Lampung Dora Rinova Universitas Bandar Lampung Yanuarius Yanu Dharmawan Universitas Bandar Lampung ABSTRACT The lack of information relating to the general locations in Lampung makes the tourists/people who want to go to Lampung difficult to meet the locations to be addressed. In an effort to implement the government program on the implementation of the regional autonomy law, the Lampung Provincial government wants to advance its region from the tourism sector because tourism is considered to be a high source of local government revenue. The main factors to consider is that if one is to travel, the question emerge will be about where to go, how far it is, what is interesting, and what activities can be done during the trip there, to answer the questions needed geographical insight about the mapping of tourism location. Geographic information systems are computer systems used to collect, integrate, organize, transform, manipulate, and analyze geographic data. The application of this geographic information system is built with java programming Android using ADT Bundle software which includes Eclipse as java programming language editor, ADT as plug-in for Eclipse, and SDK for the development of Android based application. This application will give benefit for tourists and the people who want to search good places to visit in Lampung. Keywords: Mapping, Tourism, Android programming 1. INTRODUCTION Tourism is an asset that is considered to be tangible and intangible with its attraction. -
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. -

A Case Study of the 2018 Sunda Strait Tsunami K
Pakoksung et al. Geosci. Lett. (2020) 7:15 https://doi.org/10.1186/s40562-020-00165-5 RESEARCH LETTER Open Access Global optimization of a numerical two-layer model using observed data: a case study of the 2018 Sunda Strait tsunami K. Pakoksung1*, A. Suppasri1, A. Muhari2, Syamsidik3,4 and F. Imamura1 Abstract Following the eruption of Mount Anak Krakatau, a considerable landslide occurred on the southwestern part of the volcano and, upon entering the sea, generated a large tsunami within the Sunda Strait, Indonesia, on December 22, 2018. This tsunami traveled ~ 5 km across the strait basin and inundated the shorelines of Sumatra and Java with a vertical runup reaching 13 m. Following the event, observed feld data, GPS measurements of the inundation, and multibeam echo soundings of the bathymetry within the strait were collected and publicly provided. Using this data- set, numerical modeling of the tsunami was conducted using the two-layer (soil and water) TUNAMI-N2 model based on a combination of landslide sources and bathymetry data. The two-layer model was implemented to nest the grid system using the fnest grid size of 20 m. To constrain the unknown landslide parameters, the diferential evolu- tion (DE) global optimization algorithm was applied, which resulted in a parameter set that minimized the deviation from the measured bathymetry after the event. The DE global optimization procedure was efective at determining the landslide parameters for the model with the minimum deviation from the measured seafoor. The lowest devia- tion from the measured bathymetry was obtained for the best-ftting parameters: a maximum landslide thickness of 301.2 m and a landslide time of 10.8 min. -
The Tale of Lampung Submerged
The Newsletter | No.61 | Autumn 2012 8 | The Study The tale of Lampung submerged I beg you, good sirs, everyone and all, Do not deride me for erroneous recall. The reason this story I do now narrate, Is to remind all of Lampung’s sad fate.2 As the history books have recorded, one of the world’s most cataclysmic volcanic outbursts was the 1883 eruption of Mount Krakatau, situated in the Sunda Strait that separates the Indonesian islands of Sumatra and Java. The eruption nearly wiped out the entire island of Krakatau, but after a number of submarine eruptions starting in 1927 it became clear that a new island was starting to emerge in the original location. Known as Gunung Anak Krakatau (‘The Child of Krakatau’), it is, like its predecessor, an active volcano, which continues to grow consistently. Suryadi THE FIRst KNOWN MENTION of Krakatau in the West is on and the accompanying tsunami swept the shores of Sunda some works that are relatively recent, such as Simon the 1584 map by Lucas Janszoon Waghenaer, who labeled the Strait, with waves reaching heights of forty meters at the Winchester’s bestselling book, Krakatoa: The Day the area ‘Pulo Carcata’.3 Since then the name Krakatau has been var- shore, taking the lives of – to cite the words of the colonial-era World Exploded: August 27, 1883 (London: Viking, 2003), iously represented as Rakata, Krakatoa, and more rarely Krakatoe journalist, A. Zimmerman – “thirty-seven Europeans and over suggesting that interest in Krakatau is still very much and Krakatao. Its first known eruption occurred in 416 A.D.
