Abstract

Structural pattern in Sumatra controlled by oblique subduction between Eurasian Plate with Indo-Australian Plate, resulting the structure dominated by strike-slip dextral faults. According to the position of subduction, the strike slip fault generally trending northwest-southeast.The older faults that already formed in the basement rocks (pre-rift) reactivated become normal faults under the influence of transtensional (syn-rift). This tectonic process then produce some tertiary sedimentary basin in the adjacent area. Furthermore, in the Late Tertiary it is reactivated again under the influence of transpressional (post-rift). This later tectonic event cause all sedimentary rock strongly folded and faulted, followed by magmatism/volcanism activity. This whole tectonic activity produced the Barisan Mountain Range.The transpressional process created high and low area, which could make the basement rock uplifted and separate the distribution of tertiary sedimentary in the different locations.

Abstract

Sistem Informasi Geografis (SIG) merupakan perangkat informatif yang cepat dan mudah diakses setelah semua data informasi digabungkan ke dalam suatu perangkat lunak (soft-ware) komputer.Banyak manfaat yang didapat dari SIG ini. Aplikasinya dapat digunakan untuk bidang sosial, ekonomi, politik, budaya, maupun pertahanan dan keamanan. Selain itu, SIG tersebut juga bermanfaat bagi aplikasi penanganan bencana-bencana alam seperti bencana longsor (gerakan tanah), tsunami, gempa dan lain-lain, juga dalam penetapan kawasan rawan banjir (Sukiyah, et al., 2004).

Abstract

Nyalindung area is known for its collection of abundant mollusca fauna. That fossils are contained in the sandstone and silt. Nyalindung area became a location type for Nyalindung Formation. Nyalindung Formation spread from the north district Nyalindung, there is along Cimandiri drainage area, to Bantarkalong Village and Cimerang high plains. This formation is spread to Bojonglopang shoutheastern, there is along the road of Nyalindung-Bojonglopang.Determination of age based on the collection of molluscas. Found 18% of Recent species that show Miocene age, based on clues fossil prompts (Siposiprarea caputviverae and Vicaria veurnelli Calossa) that indicate of Middle Miocene age. Based on forams L. (tribiolepidina) ruteeni and L. (tribiolepidina) kalahabensis showed Tf-3 age. Deposition environment of Nyalindung Formation based on lithology, paleontology and sedimentary structures. As a whole of deposition occurs in the open sea in the vicinity of Cileungsir river to estuaries up around the marshy area of western and eastern section investigation.

Abstract

The northern part Cianjur based on the Regional Hazard Map of Mount Gede in West Java (kaswanda, 1994) is an explosion hazard areas. The rapid economic development, especially in the tourism sector resulting in increased occupancy, hotel or villa. As a result of the growth area of the building, and the increase of population, and transfer of land use, has resulted in the handling of the impact so that the necessary pre-disaster management in which one of them is a disaster mitigation. Determination of the level of risk is one basis for determining mitigation measures related to spatial planning. The main risk factors of natural disasters include volcanic eruption hazard factors, vulnerability and resilience. Factors will affect the hazard mitigation measures that will be done in the danger area. The primary hazard mitigation in the area would have been different in the secondary area. Thus the delineation is an important step that must be done before determining the level of risk. Determination of the spatial areas prone to natural disasters Volcanic eruptions, can be done with the mitigation measures related to spatial planning based on risk level.

Abstract

Java Island is a region of frequent earthquakes with varying strength. Most of destructive earthquakes measuring over 5.6 on the Richter Scale, as a shallow earthquake with a depth of less than 30 KM. On land, the earthquake can damage a variety of infrastructure and endanger lives. At ocean, earthquakes tend to be a potential tsunami. The tsunami that ever happens is in the south of Pangandaran beach on July 27, 2006. To reduce the impact of the earthquake disaster, the identification and mitigation is required. In the identification of the earthquake in the mainland, the earthquake potential of fault-lines are shown on a large faults, there are: Earthquake's Row of Zone Bayah, Earthquake Row of Baribis Zone, Earthquake Row of Cimandiri Zone, Earthquake Row of Lembang Zone, Earthquake Row of Citanduy Zone. On the identification of the earthquake in the ocean, is required analysis to see the condition of the epicenter in the southern Teluk Pelabuhan Ratu. Mitigation of earthquake disaster can be done, among others through the various activities that need to be socialized, assisted by experts from various disciplines.

Abstract

Walat hills in the area of Sukabumi, has a pattern of east-west trending ridge. Hills line orientation is controlled by the structure of fold with is followed by formation of reverse fault. Both of geological structures is formed on the same tectonic period, on Plio-Plistocene. Position of the axis of the fold and reverse fault parallel relative to each other, based on the tectonic formation occurs in the same period, it can be classified as a pattern of thrust folds structure. Of some reverse faults that developed in Walat Area, the reverse fault whose position to northward is major reverse fault, so that by referring to the model structure of Boyer and Elliote (1982), it can be classified as a leading thrust system. This structural pattern is controling topographical differences of the hills with plain morphology in northern.

Abstract

This paper is about the geological history of the area Sukabumi-Pelabuhan Ratu, is an article from the author prepared in 1999, when the author is still active as a staff lecturer at the Faculty of Engineering Geology, Unpad. Historical geology of Sukabumi-Pelabuhan Ratu, interesting to learn, especially the most ancient rocks (Ciletuh Formation) to the youngest rocks. Tectonic framework is also interesting to learn, especially because of the influence of Indo-Australia plates are moving toward the north and subducting the Eurasian plate.
