Yangsan Fault is a seismic fault in southeastern Korea [1] [2] [3] [4] [5] which was responsible for the 5.7 Mw Gyeongju earthquake in 2016. It is located between Yeongdeok County and Busan with Yangsan.
Alexander Island,which is also known as Alexander I Island,Alexander I Land,Alexander Land,Alexander I Archipelago,and Zemlja Alexandra I,is the largest island of Antarctica. It lies in the Bellingshausen Sea west of Palmer Land,Antarctic Peninsula from which it is separated by Marguerite Bay and George VI Sound. The George VI Ice Shelf entirely fills George VI Sound and connects Alexander Island to Palmer Land. The island partly surrounds Wilkins Sound,which lies to its west. Alexander Island is about 390 kilometres (240 mi) long in a north–south direction,80 kilometres (50 mi) wide in the north,and 240 kilometres (150 mi) wide in the south. Alexander Island is the second-largest uninhabited island in the world,after Devon Island.
The Highland Boundary Fault is a major fault zone that traverses Scotland from Arran and Helensburgh on the west coast to Stonehaven in the east. It separates two different geological terranes which give rise to two distinct physiographic terrains:the Highlands and the Lowlands,and in most places it is recognisable as a change in topography. Where rivers cross the fault,they often pass through gorges,and the associated waterfalls can be a barrier to salmon migration.
The Elsinore Fault Zone is a large right-lateral strike-slip geological fault structure in Southern California. The fault is part of the trilateral split of the San Andreas fault system and is one of the largest,though quietest faults in Southern California.
Korea New Network (KNN) is the biggest regional free-to-air commercial broadcasting station based in Centum City,a high-tech media development complex within Haeundae in Busan,South Korea. KNN is affiliated with SBS. It was originally founded in April 1994 as Pusan Broadcasting Corporation (PSB). It had first begun its demo transmissions upon its establishment in April,and later on September 7 the same year it had begun its test transmissions,and then commenced its official broadcasts on May 14,1995. As of 2011 its own programs make up to 35 percent of all programs.
Mary Lou Zoback is an American geophysicist and seismologist. A specialist in tectonic stress and natural hazards risks,she spent most of her career as a research scientist with the United States Geological Survey. Zoback chaired the World Stress Map project of the International Lithosphere Program from 1986 to 1992. Zoback served on the U.S. Nuclear Waste Technical Review Board from 2012 to 2018.
The Enriquillo–Plantain Garden fault zone is a system of active coaxial left lateral-moving strike slip faults which runs along the southern side of the island of Hispaniola,where Haiti and the Dominican Republic are located. The EPGFZ is named for Lake Enriquillo in the Dominican Republic where the fault zone emerges,and extends across the southern portion of Hispaniola through the Caribbean to the region of the Plantain Garden River in Jamaica.
The Puget Sound faults under the heavily populated Puget Sound region of Washington state form a regional complex of interrelated seismogenic (earthquake-causing) geologic faults. These include the:
The Wellington Fault is an active seismic fault in the southern part of the North Island of New Zealand. It is a dextral (right-lateral) strike-slip fault with variable amounts of vertical movement causing uplift to the northwest,as expressed by a series of ranges. It forms part of the North Island Fault System,which accommodates the transfer of displacement along the oblique convergent boundary between the Indo-Australian Plate and Pacific Plate.
The 1983 Sea of Japan earthquake occurred on May 26,1983 at 11:59:57 local time. It had a magnitude of 7.8 on the moment magnitude scale. It occurred in the Sea of Japan,about 100 km west of the coast of Noshiro in Akita Prefecture,Japan. Out of the 104 fatalities,all but four were killed by the resulting tsunami,which struck communities along the coast,especially Aomori and Akita Prefectures and the east coast of Noto Peninsula. Images of the tsunami hitting the fishing harbor of Wajima on Noto Peninsula were broadcast on TV. The waves exceeded 10 meters (33 ft) in some areas. Three of the fatalities were along the east coast of South Korea. The tsunami also hit Okushiri Island,the site of a more deadly tsunami 10 years later.
The 1169 Sicily earthquake occurred on 4 February 1169 at 08:00 local time on the eve of the feast of St. Agatha of Sicily. It had an estimated magnitude of between 6.4 and 7.3 and an estimated maximum perceived intensity of X (Extreme) on the Mercalli intensity scale. The cities of Catania,Lentini and Modica were severely damaged,and the earthquake also triggered a paleotsunami. Overall,the earthquake is estimated to have caused the deaths of at least 15,000 people.
The Yakima Fold Belt of south-central Washington,also called the Yakima fold-and-thrust belt,is an area of topographical folds raised by tectonic compression. It is a 14,000 km2 (5,400 sq mi) structural-tectonic sub province of the western Columbia Plateau Province resulting from complex and poorly understood regional tectonics. The folds are associated with geological faults whose seismic risk is of particular concern to the nuclear facilities at the Hanford Nuclear Reservation and major dams on the Columbia and Snake Rivers.
The 2016 Gyeongju earthquake occurred on September 12 near Gyeongju,South Korea. Measuring 5.8 on the local magnitude scale,it was the strongest earthquake in the country until the following year. The 2017 Pohang earthquake caused more damage despite being equal in magnitude. An hour before,at 07:44:32 local time,a ML 5.1 foreshock occurred.
The 1838 San Andreas earthquake is believed to be a rupture along the northern part of the San Andreas Fault in June 1838. It affected approximately 100 km of the fault,from the San Francisco Peninsula to the Santa Cruz Mountains. It was a strong earthquake,with an estimated moment magnitude of 6.8 to 7.2,making it one of the largest known earthquakes in California. The region was lightly populated at the time,although structural damage was reported in San Francisco,Oakland,and Monterey. It is unknown whether there were fatalities. Based on geological sampling,the fault created approximately 1.5 meters of slip.
Honggeertu is a volcanic field in China,in the Nei Mongol Province.
The Palu-Koro Fault or Palu-Koro Fault System is a major active NNW-SSE trending left-lateral strike-slip fault zone on the island of Sulawesi in Indonesia. It caused the 2018 Sulawesi earthquake and tsunami.
The geology of South Korea includes rocks dating to the Archean and two large massifs of metamorphic rock as the crystalline basement,overlain by thick sedimentary sequences,younger metamorphic rocks and volcanic deposits. Although extent is small,Geology is diverse,and there are diverse rocks that were formed during the Precambrian to Cenozoic Era in the Korea Peninsula.
The geology of Croatia has some Precambrian rocks mostly covered by younger sedimentary rocks and deformed or superimposed by tectonic activity.
Meers Fault is a fault in Oklahoma that extends from Kiowa County to Comanche County. It is marked by a 22–26 kilometers (14–16 mi) long conspicuous fault scarp but the fault extends beyond the ends of this scarp. The Meers fault is part of a group of faults that lie between the Anadarko Basin and the Wichita Mountains.
The Lompoc earthquake of 1927 occurred at 5:49 a.m. Pacific Standard Time (PST),on November 4 with an epicenter off the coast of Lompoc,Santa Barbara County in Southern California. It is one of the largest earthquakes to have occurred off the coast of California,measuring a surface-wave magnitude of 7.3. The earthquake may have originated along the Hosgri Fault,an entirely offshore structure. Shaking from the earthquake and an unusually large tsunami caused some damage to communities near the earthquake. Due to its location and the area being sparsely populated at the time,there were no human fatalities reported. It is the only California-generated tsunami recorded in Hawaii.
