1938 Banda Sea Earthquake
The 1938 Banda Sea earthquake occurred on February 2 with an estimated magnitude of 8.5–8.6 on the moment magnitude scale and a Rossi–Forel intensity of VII (''Very strong tremor''). This oblique-slip event generated destructive tsunamis of up to 1.5 metres in the Banda Sea region, but there were no deaths. Tectonic setting The Banda Sea is located within a very complex tectonic regime that accommodates the convergence between the Australian Plate and the Sunda Plate. The Molucca Sea Plate, Bird's Head Plate, Timor Plate, and Banda Sea Plate all help accommodate the elaborate plate boundary system in the region. This collection of microplates leads to large amounts of seismicity in the area, including the 1852 Banda Sea earthquake which was potentially a 8.8 event, as well as the 1629 Banda Sea earthquake which was also estimated at up to 8.8. Earthquake At around 04:00 local time, a large earthquake started to shake the Banda islands. With a moment magnitude () of 8.5–8 ...

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 ...

Kai Islands
The Kai Islands (also Kei Islands) of Indonesia are a group of islands in the southeastern part of the Maluku Islands, located in the province of Maluku (province), Maluku. The Moluccas have been known as the Spice Islands due to regionally specific plants such as nutmeg, mace (spice), mace, and cloves that originally intrigued the European nations of the 16th century. Though originally Melanesians, Melanesian, many islanders were exterminated in the 17th century during the Dutch–Portuguese War, spice wars, particularly in the Banda Islands. A second influx of Austronesian peoples, Austronesian immigrants began in the early 20th century under the Dutch East Indies, Dutch and continued in the Indonesian era. Administrative divisions The Kai Islands consist of the two distinct second-tier administrations, both in Maluku Province. The Southeast Maluku Regency (Maluku Tenggara) is sub-divided into eleven administrative Districts of Indonesia, districts (''kecamatan''). Though ...

Megathrust Earthquakes In Indonesia
Megathrust earthquakes occur at convergent plate boundaries, where one tectonic plate is forced underneath another. The earthquakes are caused by slip along the thrust fault that forms the contact between the two plates. These interplate earthquakes are the planet's most powerful, with moment magnitudes (''Mw'') that can exceed 9.0. Since 1900, all earthquakes of magnitude 9.0 or greater have been megathrust earthquakes. The thrust faults responsible for megathrust earthquakes often lie at the bottom of oceanic trenches; in such cases, the earthquakes can abruptly displace the sea floor over a large area. As a result, megathrust earthquakes often generate tsunamis that are considerably more destructive than the earthquakes themselves. Teletsunamis can cross ocean basins to devastate areas far from the original earthquake. Terminology and mechanism The term ''megathrust'' refers to an extremely large thrust fault, typically formed at the plate interface along a subduction zone ...

National Geophysical Data Center
The United States National Geophysical Data Center (NGDC) provided scientific stewardship, products and services for geophysical data describing the solid earth, marine, and solar-terrestrial environment, as well as earth observations from space. In 2015, NGDC was merged with the National Climatic Data Center (NCDC) and the National Oceanographic Data Center (NODC) into the National Centers for Environmental Information (NCEI). Location and controlling bodies The NGDC, was located in Boulder, Colorado as a part of the US Department of Commerce (USDOC), National Oceanic & Atmospheric Administration (NOAA), National Environmental Satellite, Data and Information Service (NESDIS). Data holdings NGDC's data holdings contained more than 300 digital and analog databases, some of which were very large. As technology advanced, so did the search for more efficient ways of preserving these data. This data is now maintained by the NCEI. Data contributors NGDC worked closely with contri ...

International Seismological Centre
The International Seismological Centre (ISC) is a non-governmental, nonprofit organisation charged with the final collection, definitive analysis and publication of global seismicity. The ISC was formed in 1964 as an international organisation independent of national governments that would carry on the work of the International Seismological Summary in collecting and analyzing seismic data from around the world, and particularly to handle increased flow of data from the World-Wide Standard Seismograph Network (WWSSN), also established that year. The ISC considers its prime task to be the collection and re-analysis of all available earthquake seismic date in order to produce definitive data on earthquakes. The ISC's catalog is considered "the most complete and authoritative final depository of global earthquake parameter data." Purpose The main scientific goal of the Centre is the definitive compilation of earthquake information and the readings on which they are based. Collecti ...

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.

List Of Earthquakes In 1938
This is a list of earthquakes in 1938. Only magnitude 6.0 or greater earthquakes appear on the list. Lower magnitude events are included if they have caused death, injury or damage. Events which occurred in remote areas will be excluded from the list as they wouldn't have generated significant media interest. All dates are listed according to UTC time. This was once again a very busy year with 22 events reaching 7.0+. Topping the list was a huge quake which struck the Banda Sea, Dutch East Indies in February. At a magnitude of 8.5 this was one of the largest earthquakes of all time. Despite the large size no deaths were reported. Despite the array of large events, the death toll for the year was only 296. Turkey saw the majority of the deaths due to a 6.6 magnitude event in April. November saw a series of large quakes strike off the east coast of Honshu, Japan. Also in November was a magnitude 8.3 which struck Alaska. Generally Dutch East Indies and Japan saw most of the large 7 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
