Citarik Fault
The Citarik Fault is a strike-slip fault that cuts across West Java, Western Java, Indonesia, passing through Pelabuhan Ratu, Bogor and Bekasi. It is a long crack in the earth’s Crust (geology), crust where two tectonic plates move past each other. The fault has been active since the Middle Miocene period, about 15 million years ago. Tectonical history At first, the Citarik Fault was a transtensional fault, meaning that the plates were moving apart and creating space for new crust to form. However, since the Plio-Pleistocene period, about 5 million years ago, the fault has changed into a left strike-slip fault, meaning that the plates are sliding horizontally past each other in opposite directions. Characteristics This fault is an Left-Lateral Strike-Slip type fault and has a length of about 250 km, However this fault is segmented and divided into three segments: the southern, central, and northern segments, each with different characteristics and seismic potentials.

Middle Miocene
The Middle Miocene is a sub-epoch of the Miocene Epoch made up of two stages: the Langhian and Serravallian stages. The Middle Miocene is preceded by the Early Miocene The Early Miocene (also known as Lower Miocene) is a sub-epoch of the Miocene Epoch made up of two stages: the Aquitanian and Burdigalian stages. The sub-epoch lasted from 23.03 ± 0.05 Ma to 15.97 ± 0.05 Ma (million years ago). It was p .... The sub-epoch lasted from 15.97 ± 0.05 Ma to 11.608 ± 0.005 Ma (million years ago). During this period, a sharp drop in global temperatures took place. This event is known as the Middle Miocene Climate Transition. For the purpose of establishing European Land Mammal Ages this sub-epoch is equivalent to the Astaracian age. External links GeoWhen Database - Middle Miocene .02 02 * * {{geochronology-stub ...

List Of Earthquakes In Indonesia
__NOTOC__ This is an incomplete list of more recent recorded major earthquakes that have occurred within the boundaries of Indonesia. The determinants of the activity are indicated by the geology of the region, and the volcanic activity. Large numbers of earthquakes of smaller magnitude occur very regularly due to the meeting of major tectonic plates in the region. Based on the records of the USGS, Indonesia has had more than 150 earthquakes with magnitude > 7 in the period 1901–2019.

Baribis Fault
The Baribis Fault ( id, Sesar Baribis) is a geological feature located in the northern part of Java. This fault, estimated to be long, stretches from Purwakarta to Lebak Regency and is a threat to the Jakarta metropolitan area because the fault is partially located within the metropolitan area itself. Characteristics The fault is estimated at 100 km long and stretches from Purwakarta to Lebak Regency, moving at a rate of 5 mm a year. It is a thrust fault formed during the Pliocene era. It divides into two segments. Fault activity Half of the fault is locked but it caused a large earthquake in 1834 which resulted in five deaths and serious damage in West Java. It sometimes causes small earthquakes. Hazard The fault passes through the Jakarta metropolitan area, which has a population of more than 30 million, where an earthquake could cause huge loss of life and damage.

Jakarta ranks first among the Indonesian provinces in human development index. Jakar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jakarta Metropolitan Area
The Jakarta metropolitan area or Greater Jakarta, known locally as Jabodetabek (an acronym of Jakarta–Bogor– Depok–Tangerang–Bekasi), and sometimes extended to Jabodetabekjur (with the acronym extended to include part of Cianjur Regency), or Jabodetabekpunjur (further extended to include Puncak and the Cipanas district), is the most populous metropolitan area in Indonesia. It includes the national capital (Jakarta Special Capital Region, as the core city) as well as five satellite cities and three complete regencies. The original term "Jabotabek" dated from the late 1970s and was revised to "Jabodetabek" in 1999 when "De" (for "Depok") was inserted into the name following its formation. The term "Jabodetabekjur" or "Jabodetabekpunjur" was legalised on the Presidential Regulation Number 54 of 2008, although the name Jabodetabek is more commonly used. The area comprises Jakarta Special Capital Region and parts of West Java and Banten provinces, specifically the thre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earthquake
An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves. Earthquakes can range in intensity, from those that are so weak that they cannot be felt, to those violent enough to propel objects and people into the air, damage critical infrastructure, and wreak destruction across entire cities. The seismic activity of an area is the frequency, type, and size of earthquakes experienced over a particular time period. The seismicity at a particular location in the Earth is the average rate of seismic energy release per unit volume. The word ''tremor'' is also used for Episodic tremor and slip, non-earthquake seismic rumbling. At the Earth's surface, earthquakes manifest themselves by shaking and displacing or disrupting the ground. When the epicenter of a large earthquake is located offshore, the seabed may be displaced sufficiently to cause ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plio-Pleistocene
The Plio-Pleistocene is an informally described geological pseudo-period, which begins about 5 million years ago (Mya) and, drawing forward, combines the time ranges of the formally defined Pliocene and Pleistocene epochs—marking from about 5 Mya to about 12 kya. Nominally, the Holocene epoch—the last 12 thousand years—would be excluded, but most Earth scientists would probably treat the current times as incorporated into the term "Plio-Pleistocene"; see below. In the contexts of archaeology, paleontology, and paleoanthropology, the Plio-Pleistocene is a very useful period to which scientists may assign the long and continuous run in East Africa of datable sedimentary layers and their contents (e.g. the Bouri Formation). These contents collectively present a focused view of the continuous evolution of the region's large vertebrates, especially the evolution of some African apes ( hominids) to the earliest hominins; and then the development of the early humans ...

Tectonic Plates
Plate tectonics (from the la, label=Late Latin, tectonicus, from the grc, τεκτονικός, lit=pertaining to building) is the generally accepted scientific theory that considers the Earth's lithosphere to comprise a number of large tectonic plates which have been slowly moving since about 3.4 billion years ago. The model builds on the concept of ''continental drift'', an idea developed during the first decades of the 20th century. Plate tectonics came to be generally accepted by geoscientists after seafloor spreading was validated in the mid to late 1960s. Earth's lithosphere, which is the rigid outermost shell of the planet (the crust and upper mantle), is broken into seven or eight major plates (depending on how they are defined) and many minor plates or "platelets". Where the plates meet, their relative motion determines the type of plate boundary: '' convergent'', '' divergent'', or '' transform''.

West Java
West Java ( id, Jawa Barat, su, ᮏᮝ ᮊᮥᮜᮧᮔ᮪, romanized ''Jawa Kulon'') is a province of Indonesia on the western part of the island of Java, with its provincial capital in Bandung. West Java is bordered by the province of Banten and the country's capital region of Jakarta to the west, the Java Sea to the north, the province of Central Java to the east and the Indian Ocean to the south. With Banten, this province is the native homeland of the Sundanese people, the second-largest ethnic group in Indonesia. West Java was one of the first eight provinces of Indonesia formed following the country's independence proclamation and was later legally re-established on 14 July 1950. In 1966, the city of Jakarta was split off from West Java as a 'special capital region' (), with a status equivalent to that of a province, while in 2000 the western parts of the province were in turn split away to form a separate Banten province. Even following these split-offs, West J ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crust (geology)
In geology, the crust is the outermost solid shell of a rocky planet, dwarf planet, or natural satellite. It is usually distinguished from the underlying mantle by its chemical makeup; however, in the case of icy satellites, it may be distinguished based on its phase (solid crust vs. liquid mantle). The crusts of Earth, Mercury, Venus, Mars, Io, the Moon and other planetary bodies formed via igneous processes and were later modified by erosion, impact cratering, volcanism, and sedimentation. Most terrestrial planets have fairly uniform crusts. Earth, however, has two distinct types: continental crust and oceanic crust. These two types have different chemical compositions and physical properties and were formed by different geological processes. Types of crust Planetary geologists divide crust into three categories based on how and when it formed. Primary crust / primordial crust This is a planet's "original" crust. It forms from solidification of a magma ocean. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
