Query: Where is the fault line for Hawaii located?
The Koa’e Fault Zone (pronounced coe-wah-hee) is a series of fault scarps connecting the East and Southwest Rift Zones on Kilauea Volcano on the Big Island of Hawaii. The fault zone intersects the East Rift near the Pauahi Crater and extends nearly 12 kilometers in an east-northeast direction towards the westernmost boundary near Mauna Iki and the Southwest Rift Zone. Boundaries of the Koa’e Fault Zone also cover 2 kilometers in a north-south orientation along the 12 kilometer length. It is believed that the fault zone has been active for tens of thousands of years. The area is infrequently visited by park patrons due to the lack of eruptive activity and closure of certain areas to the general public.
The Middle America Trench is a major subduction zone, an oceanic trench in the eastern Pacific Ocean off the southwestern coast of Middle America, stretching from central Mexico to Costa Rica. The trench is 1,700 miles (2,750 km) long and is 21,880 feet (6,669 m) at its deepest point.
The trench is the boundary between the Rivera, Cocos, and Nazca plates on one side and the North American and Caribbean plates on the other. It is the 18th-deepest trench in the world. Many large earthquakes have occurred in the area of the Middle America Trench.
This earthquake is the strongest event recorded in the Hyūga-nada Sea region. The maximum slip was estimated to be 4 m. It was estimated that, in the Hyūga-nada Sea region, earthquakes with magnitudes about 7.6 occur with a period of about 200 years, while earthquakes with magnitudes about 7.1 occur with a period of about 20 to 27 years. It has been pointed out that there is a tendency of occurrence of inland earthquakes in Kyushu before and after large interplate earthquakes in the Hyūga-nada Sea region.
Caraga Region is one of the regions notably located in the eastern seaboard of the Philippines. With its geographic location facing the Pacific Ocean and famous Philippine Trench, the Region is prone to various weather conditions and geologic phenomenon like, but not limited to, typhoon, tsunami and other coastal surges and seismic activities. With these, DENR-MGB13 is expeditiously utilizing its human and financial resources to generate geohazard maps as necessary source of information to spatial planners and other government and non-government agencies working for public safety and disaster management.

Fiji is the hub of the South West Pacific, midway between Vanuatu and Tonga. The archipelago is located between 176° 53′ east and 178° 12′ west. The 180° meridian runs through Taveuni but the International Date Line is bent to give uniform time (UTC+12) to all of the Fiji group. With the exception of Rotuma, the Fiji group lies between 15° 42′ and 20° 02′ south. Rotuma is located north of the group, from Suva, 12° 30′ south of the equator.
The Doty Fault – the southernmost of the uplift-and-basin dividing faults reviewed here, and located just north of the Chehalis Basin – is one of nearly a dozen faults mapped in the Centralia—Chehalis coal district in 1958. While the towns of Centralia and Chehalis in rural Lewis County may seem distant (about 25 miles) from Puget Sound, this is still part of the Puget Lowland, and these faults, the local geology, and the underlying tectonic basement seem to be connected with that immediately adjacent to Puget Sound. And though the faults in this area are not notably seismogenic, the southeast striking faults seem to be "en echelon" with the Olympia structure (fault?), and headed for the definitely active Saint Helens Zone; this appears to be a large-scale structure. The Doty fault particularly seems to have gained prominence with geologists since it was associated with an aeromagnetic anomaly, and a report in 2000 credited it capable of a magnitude 6.7 to 7.2 earthquake. The prospect of a major earthquake on the Doty Fault poses a serious hazard to the entire Puget Sound region as it threatens vital economic lifelines: At Chehalis there is but a single freeway (Interstate 5) and a single rail line connecting the Puget Sound region with the rest of the west coast; the only alternate routes are very lengthy.
Volcanoes in the Andes occur in four separate regions: the Northern Volcanic Zone between 2°N and 5°S, the Central Volcanic Zone between 16°S and 28°S, the Southern Volcanic Zone between 33°S and 46°S, and the Austral Volcanic Zone, south of the Southern Volcanic Zone. These volcanic zones are separated by areas where recent volcanism is absent; one common theory is that the subduction processes responsible for volcanism form a subducting plate that is too shallow to trigger the formation of magma. This shallow subduction appears to be triggered by the Nazca Ridge and the Juan Fernandez Ridge; the areas where they subduct beneath the Peru-Chile Trench coincide with the limits of the Central Volcanic Zone. It is possible that when these ridges are subducted, the buoyancy they carry disrupts the subduction process and reduces the supply of water, which is important for the formation of melts.

North of this area, on the slope of Mt Haszard, is Inferno Crater, filled with a striking pale blue lake of highly acidic water with a pH as low as 2.2. The crater was blasted into the side of the mountain as part of the 1886 Mount Tarawera eruption event and remains the site of the largest geyser-like feature in the world. Although the actual geyser plays at the bottom of the lake and cannot be seen, a handful of active fumaroles are visible on the shore and the cliff face behind the lake. The water level of this up-to- lake follows a complicated rhythmic cycle that is interconnected with the nearby Frying Pan Lake.
The north coast of Honduras borders the Caribbean Sea and the Pacific Ocean lies south through the Gulf of Fonseca. Honduras consists mainly of mountains, with narrow plains along the coasts. A large undeveloped lowland jungle, "La Mosquitia" lies in the northeast, and the heavily populated lowland Sula valley in the northwest. In La Mosquitia lies the UNESCO world-heritage site Río Plátano Biosphere Reserve, with the Coco River which divides Honduras from Nicaragua.
The different volcanic zones are intercalated by volcanic gaps, zones that, despite lying at the right distance from an oceanic trench, lack volcanic activity. The Andes has three major volcanic gaps the "Peruvian flat-slab segment" (3 °S–15 °S), the "Pampean flat-slab segment" (27 °S–33 °S) and the "Patagonian Volcanic Gap" (46 °S–49 °S). The first one separates the Northern from the Central Volcanic Zone, the second the Central from the Southern and the last separates the Southern from the Austral Volcanic Zone. The Peruvian and Pampean gaps coincide with areas of flat slab (low angle) subduction and therefore the lack of volcanism is believed to be caused by the shallow dip of the subducting Nazca Plate in these places. The shallow dip has in turn been explained by the subduction of the Nazca Ridge and the Juan Fernández Ridge for the Peruvian and Pampean gaps respectively. Since the Nazca and Juan Fernández Ridge are created by volcanic activity in Pacific hotspots (Easter and Juan Fernández) it can be said that volcanic activity in the Pacific is responsible for the suppression of volcanism in parts of the Andes.
Off the western coast of South America, the Nazca Plate subducts beneath the South America Plate at a rate of about ; this subduction is responsible for volcanic activity in the Central Volcanic Zone and elsewhere in the Andes. Volcanism does not occur along the entire length of the subduction zone; north of 15° and south of 28° the subducting plate moves downward at a shallower angle and this is associated with the absence of volcanic activity. Other volcanic zones exist in the Andes, including the Northern Volcanic Zone in Colombia and Ecuador and the Southern Volcanic Zone also in Chile. A furtherourth volcanic zone, the Austral Volcanic Zone, is caused by the subduction of the Antarctic Plate beneath the South America Plate and lies south of the Southern Volcanic Zone.
The Tucura Fault is located in the northern part of the Central Ranges of the Colombian Andes, west of the Romeral Fault System. It extends from the Paderisco River in the south to the Sinú Valley in the north, where it crosses the Serranía de Abibe. The fault crosscuts middle and upper Tertiary folded marine sedimentary rocks and Quaternary alluvial deposits. The fault controls drainage, forms linear ridges, topographic lineaments, and fault scarps about high on Quaternary terraces south of the town of Dabeiba, Antioquia. There are strong linear features on the right margin of the Esmeralda and Sinú Rivers; these include fault saddles and slight slope changes in alluvial terraces. Tertiary rock units are thrust over Quaternary deposits and striae are found on the shear planes.
The highest mountains above sea level are generally not the highest above the surrounding terrain. There is no precise definition of surrounding base, but Denali, Mount Kilimanjaro and Nanga Parbat are possible candidates for the tallest mountain on land by this measure. The bases of mountain islands are below sea level, and given this consideration Mauna Kea ( above sea level) is the world's tallest mountain and volcano, rising about from the Pacific Ocean floor. Ojos del Salado has the greatest rise on Earth— from the summit to the bottom of the Atacama Trench about away, though most of this rise is not part of the mountain.
The Rocky Face Fault is a geological fault responsible, in part, for the location of Cumberland Gap at Cumberland Mountain and the Narrows gap at Pine Mountain in the southern Appalachian mountain range. The fact that these two gaps lined up enabled western migration across the Appalachians to Kentucky. Included along the fault are the towns of Middlesboro and Pineville, Kentucky. The fault represents a crack in the Cumberland Overthrust Sheet, one of many remnant resistant strata pushed upwards to the northwest over the neighboring Cumberland Plateau. The fault is named after Rocky Face, a prominent, cliff-lined mountain between Middlesboro and Pineville, Kentucky.
The South Volcanic Zone (SVZ) extends roughly from Central Chile's Andes at the latitude of Santiago, at ca. 33°S, to Cerro Arenales in Aysén Region at ca. 46°S, a distance of well over 870 mi (1,400 km). The arc has formed due to subduction of the Nazca Plate under the South American Plate along the Peru–Chile Trench. The northern boundary of the SVZ is marked by the flat-slab subduction of the Juan Fernández Ridge, which is believed to have produced a volcanic gap called the "Pampean flat-slab segment" in the Norte Chico region since the late Miocene. The southern end of the SVZ is marked by the Chile Triple Junction where the Chile Rise subducts under South America at the Taitao Peninsula giving origin to the "Patagonian Volcanic Gap". Further south lies the Austral Volcanic Zone.
Ambato lies in the main valley of the Central Cordillera, the highest of the Andean mountain ranges. The city itself is carved into the side of Cerro Casigana, the mountain that dominates the north end of the city. From Ambato, it is possible to see many snow-capped volcanoes including Cotopaxi, Tungurahua, Carihuairazo, and the largest mountain in Ecuador, Chimborazo. Tungurahua lies about 40 kilometers to the southeast. The threat of eruption from the volcano is constant. On May 16, 2006, Tungurahua erupted, covering the city with a thick layer of ash.

A supervolcano usually has a large caldera and can produce devastation on an enormous, sometimes continental, scale. Such volcanoes are able to severely cool global temperatures for many years after the eruption due to the huge volumes of sulfur and ash released into the atmosphere. They are the most dangerous type of volcano. Examples include Yellowstone Caldera in Yellowstone National Park and Valles Caldera in New Mexico (both western United States); Lake Taupo in New Zealand; Lake Toba in Sumatra, Indonesia; and Ngorongoro Crater in Tanzania. Because of the enormous area they may cover, supervolcanoes are hard to identify centuries after an eruption. Similarly, large igneous provinces are also considered supervolcanoes because of the vast amount of basalt lava erupted (even though the lava flow is non-explosive).
The Taupo Volcanic Zone is located on New Zealand's North Island. It is long by and lies over a subduction zone in the Earth's crust. Mount Ruapehu marks its southwestern end, while the submarine Whakatane volcano ( beyond White Island) is considered its northeastern limit. Many geysers in this zone were destroyed due to geothermal developments and a hydroelectric reservoir, but several dozen geysers still exist. In the beginning of the 20th century, the largest geyser ever known, the Waimangu Geyser existed in this zone. It began erupting in 1900 and erupted periodically for four years until a landslide changed the local water table. Eruptions of Waimangu would typically reach and some superbursts are known to have reached . Recent scientific work indicates that the Earth's crust below the zone may be as little as thick. Beneath this lies a film of magma wide and long.
The Septentrional-Orient fault zone (SOFZ) is a system of coaxial left lateral-moving strike slip faults that runs along the northern side of the island of Hispaniola where Haiti and the Dominican Republic are located and continues along the south of Cuba along the northern margin of the Cayman Trough. The SOFZ shares approximately half of the relative motion between the North American and Caribbean tectonic plates with the Enriquillo-Plantain Garden fault zone and Walton fault zone which run along the southern side of Hispaniola and aong the southern margin of the Cayman Trough. Both fault zones terminate at the Mid-Cayman Rise to the west. Some researchers believe that the Enriquillo-Plantain Garden fault zone and the SOFZ bound a microplate, dubbed the Gonâve Microplate, a area of the northern Caribbean Plate that is in the process of shearing off the Caribbean Plate and accreting to the North America Plate.
The earthquake created the Fukozu Fault, named after the village in the middle of the fault trace, in an area adjoining the west of the Tōkaidō Main Line railway between Okazaki and Gamagōri, Aichi Prefecture. The fault's total visible distance is little more than 9 km, but is of great interest to geologists as it has a right-angle bend in its middle part, rather than being straight or at a gentle curve. It is also remarkable in that ground displacement at the fault is up to one meter in places; however, the Tokaido Railway Line, although only 150 meters from the fault line in places, suffered no damage.
In September 2007, it was discovered that the Bow Ridge fault line ran underneath the facility, hundreds of feet east of where it was originally thought to be located, beneath a storage pad where spent radioactive fuel canisters would be cooled before being sealed in a maze of tunnels. The discovery required several structures to be moved several hundred feet further to the east, and drew criticism from Robert R. Loux, then head of the Nevada Agency for Nuclear Projects, who argues that Yucca administrators should have known about the fault line's location years prior, and called the movement of the structures "just-in-time engineering."
In June 2008, a major nuclear equipment supplier, Holtec International, criticized the Department of Energy's safety plan for handling containers of radioactive waste before they are buried at the proposed Yucca Mountain dump. The concern is that, in an earthquake, the unanchored casks of nuclear waste material awaiting burial at Yucca Mountain could be sent into a "chaotic melee of bouncing and rolling juggernauts".
Further complicating this is a feature of unknown structure and origin, the Olympic-Wallowa Lineament (OWL). This is a seemingly accidental alignment of topographic features that runs roughly east-southeast from the north side of the Olympic Peninsula to the Wallowa Mountains in northeastern Oregon. It aligns with the West Coast fault and Queen Charlotte Fault system of strike-slip fault zones (similar to the San Andreas Fault in California) on the west side of Vancouver Island, but does not itself show any significant or through-going strike-slip movement. It is of interest here because the various strands of the Seattle Fault change orientation where they appear to cross the OWL, and various other features, such as the Rosedale monocline and Olympia structure, and a great many local topographical features, have parallel alignments. It may also be the original location of the Darrington—Devils Mountain Fault (the dashed line "X" at the top of the following map). The OWL appears to be a deep-seated structure over which the shallower crust of the Puget Lowland is being pushed, but this remains speculative.
