Map Of The Eastern Sunda Arc Indonesia With Major
194 bhaskar kundu and v k gahalaut figure 1. map of the eastern sunda arc, indonesia, with major tectonic and bathymetric features of the region with earthquakes of m ≥ 4.0 from ehb catalogue (engdahl et al 1998). deeper seismicity (>450 km) is represented by pinkcolour, whereas shallow and intermediate seismicity (<450 km) is shown by red colour.from these earthquakes a wedge. The sunda arc is a volcanic arc in indonesia that formed the islands of java and sumatra, the lesser sunda islands, and the sunda strait. the arc is characterized by a series of volcanic mountains. the volcanic arc represents a convergent boundary where the eurasian tectonic plates underneath. The sunda arc is a volcanic arc that produced the islands of sumatra and java, the sunda strait and the lesser sunda islands.a chain of volcanoes forms the topographic spine of these islands the sunda arc marks an active convergent boundary between the east eurasian plates that underlie indonesia, especially the sunda plate and the burma plate, with the india and australian plates that form. The lesser sundas comprise many islands, most of which are part of indonesia and are administered as the provinces of bali, west nusa tenggara, east nusa tenggara and southern part of maluku. the eastern half of timor is part of east timor. geology. the lesser sunda islands consist of two geologically distinct archipelagos. Structural geology. the tectonics processes in indonesia formed major structures in indonesia. the most prominent fault in the west of indonesia is the semangko fault or the great sumatran fault, a dextral strike slip fault along sumatra island (about 1900 km). the formation of this fault zone is related to the subduction zone in the west of sumatra.

Geologically, the sunda shelf / ˈ s ʊ n d ʌ / is a southeast extension of the continental shelf of southeast asia. major landmasses on the shelf include the malay peninsula, sumatra, borneo, java, madura, bali and their surrounding smaller islands. it covers an area of approximately 1.85 million km 2. The nine major lesser sunda islands. sumba is an indonesian island that occupies an area of 11,153 square km in eastern indonesia. the estimated population of the island is 755,849. waingapu is the largest town on the island. what and where is the sunda arc? most popular. animals that live in the tundra. The banda arc (main arc, inner, and outer) is a set of island arcs that exist in eastern indonesia. it manifests the collision of a continent and an intra oceanic island arc. the presently active arc is located on what appears to be oceanic crust whereas the associated subduction trench is underlain by continental crust. Pdf | new geochemical data are presented from prehistoric and historical eruptive products of the lamongan volcanic field (lvf), east java; a region of the sunda arc covering similar to 260 km(2. Indonesia is an island nation in southeast asia, between south china sea and the pacific ocean (in north) and the indian ocean (in south). the country consists of many islands in the malay archipelago also known as maritime southeast asia, east indies, indonesian archipelago, and spices archipelago.

Map of the eastern sunda arc showing major tectonic features, the distribution of volcanism (including gunung lamongan and the lvf), and some major geochemical trends along the arc ( , increase; −, decrease in direction of arrow; sr ir, 87 sr/ 86 sr). The interaction of the three major plates creates a complex tectonic especially in the plate boundary that is situated in eastern indonesia. the lsi is mainly form as a result of the subduction of the indo australian plate beneath the sunda banda arc during the upper tertiary in which this subduction formed the inner volcanic arc of the lsi. Carn and pyle lamongan volcanic field, east java fig. 1. map of the eastern sunda arc showing major tectonic features, the distribution of volcanism (including gunung lamongan and the lvf), and. The arc hosts three premier porphyry cu au deposits at batu hijau, elang, and tumpangpitu (>300 t au and >5 mt cu). these giant porphyry deposits are confined to the eastern segment of the eastern sunda arc (eastern java to sumbawa), constructed on island arc crust where the roo rise is being subducted. We present the chemical and isotope (he c n) characterization of active fumaroles and hydrothermal gases and waters from the summits and flanks of 19 volcanic centers along the western sunda arc, indonesia. samples were collected over two field expeditions (1991 and 2010) and cover 13 volcanic centers in sumatra, 5 in java and one in bali.

Discovery of possible mega thrust earthquake along the seram trough from records fig. 1 map of major cities and proximity to major plate boundary segments in the indonesia region. the no large earthquakes in the banda arc and eastern indonesia region are included in the recent summary of mega thrust earthquake events. The discovery of the world class cu au deposit at tumpangpitu, east java (1.9 gt @ 0.45% cu, 0.45 g/t au), has reinforced the eastern sunda arc as a significant metallogenic belt that is highly promising for the discovery of major porphyry deposits. the arc hosts three premier porphyry cu au deposits at batu hijau, elang, and tumpangpitu (>300 t au and >5 mt cu). Back arc thrusting in the eastern sunda arc, indonesia: a consequence of arc continent collision and for this arc system the than the eastern sunda thrusts, and it may be major mechanism is. Our analysis of new bathymetric data reveals six submarine landslides at the eastern sunda margin between central java and sumba island, indonesia. their volumes range between 1 km³ in the java fore arc basin up to 20 km³ at the trench off sumba and sumbawa. we estimate the potential hazard of each event by modeling the corresponding.
