1982 Flores Earthquake
The 1982 Flores earthquake struck the island of Flores in Indonesia on December 25. Registering a moment magnitude of 5.9, according to the International Seismological Centre, it created landslides and was reportedly accompanied by a tsunami. The earthquake killed thirteen people and left 390 injured, also destroying 1,875 houses and 121 other buildings. The villages of Layahong and Oyong Barang were damaged by seven seconds of shaking. Tectonic setting The Lesser Sunda Islands lie in a region with frequent seismicity, and there is a history of tsunamis in the area. Both the subduction of the Australian Plate and the crust in the Flores Sea could be responsible for this activity. Impact The five most affected districts were evacuated of 6,000 people. The local and regional governments were petitioned for supplies like tents, medicine, and food. The earthquake was followed by several aftershocks.

Fault (geology)
In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the plane that represents the fracture surface of a fault. A ''fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone of crushed rock along a single fault. Prolonged motion along closely spaced faults can blur the ...

Lesser Sunda Islands
The Lesser Sunda Islands or nowadays known as Nusa Tenggara Islands ( id, Kepulauan Nusa Tenggara, formerly ) are an archipelago in Maritime Southeast Asia, north of Australia. Together with the Greater Sunda Islands to the west they make up the Sunda Islands. The islands are part of a volcanic arc, the Sunda Arc, formed by subduction along the Sunda Trench in the Java Sea. A bit more than 20 million people live on the islands. Etymologically, Nusa Tenggara means "Southeast Islands" from the words of ''nusa'' which means 'island' from Old Javanese language and ''tenggara'' means 'southeast'. The main Lesser Sunda Islands are, from west to east: Bali, Lombok, Sumbawa, Flores, Sumba, Savu, Rote, Timor, Atauro, Alor archipelago, Barat Daya Islands, and Tanimbar Islands.

Geography Of Flores Island (Indonesia)
Geography (from Greek: , ''geographia''. Combination of Greek words ‘Geo’ (The Earth) and ‘Graphien’ (to describe), literally "earth description") is a field of science devoted to the study of the lands, features, inhabitants, and phenomena of Earth. The first recorded use of the word γεωγραφία was as a title of a book by Greek scholar Eratosthenes (276–194 BC). Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. One such concept, the first law of geography, proposed by Waldo Tobler, is "everything is related to everything else, but near things are more related than distant things." Geography has been called "the world discipline" and "the bridge between the human and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

The 1992 Flores earthquake and tsunami occurred on December 12 on the island of Flores in Indonesia. With a magnitude of 7.8 and a maximum Mercalli intensity of VIII (''Severe''), it was the largest and also the deadliest earthquake in 1992 and in the Lesser Sunda Islands region. Description The quake hit at 13:29:26 WITA and was followed by several serious aftershocks.Reports 1–9 At least 2,500 people were killed or missing near Flores, including 1,490 at |
Aftershock
In seismology, an aftershock is a smaller earthquake that follows a larger earthquake, in the same area of the main shock, caused as the displaced crust adjusts to the effects of the main shock. Large earthquakes can have hundreds to thousands of instrumentally detectable aftershocks, which steadily decrease in magnitude and frequency according to a consistent pattern. In some earthquakes the main rupture happens in two or more steps, resulting in multiple main shocks. These are known as doublet earthquakes, and in general can be distinguished from aftershocks in having similar magnitudes and nearly identical seismic waveforms. Distribution of aftershocks Most aftershocks are located over the full area of fault rupture and either occur along the fault plane itself or along other faults within the volume affected by the strain associated with the main shock. Typically, aftershocks are found up to a distance equal to the rupture length away from the fault plane. The pattern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flores Sea
The Flores Sea covers of water in Indonesia. The sea is bounded on the north by the island of Celebes and on the south by Sunda Islands of Flores and Sumbawa. Geography The seas that border the Flores Sea are the Bali Sea (to the west), Java Sea (to the northwest), and the Banda Sea (to the east and northeast). The Indian Ocean and Savu Sea lie to the south, but are separated from the Flores Sea by various islands. Islands that border this sea are the Lesser Sunda Islands and Celebes (Sulawesi). Extent The sea is deep. The International Hydrographic Organization (IHO) defines the Flores Sea as being one of the waters of the East Indian Archipelago.

Australian Plate
The Australian Plate is a major tectonic plate in the eastern and, largely, southern hemispheres. Originally a part of the ancient continent of Gondwana, Australia remained connected to India and Antarctica until approximately when India broke away and began moving north. Australia and Antarctica began rifting and completely separated roughly . The Australian plate later fused with the adjacent Indian Plate beneath the Indian Ocean to form a single Indo-Australian Plate. However, recent studies suggest that the two plates have once again split apart and have been separate plates for at least 3 million years and likely longer. The Australian Plate includes the continent of Australia, including Tasmania, as well as portions of New Guinea, New Zealand and the Indian Ocean basin. Scope The continental crust of this plate covers the whole of Australia, the Gulf of Carpentaria, southern New Guinea, the Arafura Sea, the Coral Sea. The continental crust also includes northwestern N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subduction
Subduction is a geological process in which the oceanic lithosphere is recycled into the Earth's mantle at convergent boundaries. Where the oceanic lithosphere of a tectonic plate converges with the less dense lithosphere of a second plate, the heavier plate dives beneath the second plate and sinks into the mantle. A region where this process occurs is known as a subduction zone, and its surface expression is known as an arc-trench complex. The process of subduction has created most of the Earth's continental crust. Rates of subduction are typically measured in centimeters per year, with the average rate of convergence being approximately two to eight centimeters per year along most plate boundaries. Subduction is possible because the cold oceanic lithosphere is slightly denser than the underlying asthenosphere, the hot, ductile layer in the upper mantle underlying the cold, rigid lithosphere. Once initiated, stable subduction is driven mostly by the negative buoyancy of the de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
