2002 Papua New Guinea Earthquake
On September 9, 2002, a magnitude 7.6 earthquake struck off the coast of Wewak, Sandaun Province, Papua New Guinea. The shallow reverse earthquake triggered a local tsunami measuring 5 meters high. The disaster resulted in at least six deaths, 70 injuries and building damage. Tectonic setting The island of New Guinea lies within the complex zone of collision between the Australian Plate and the Pacific Plate. Within this overall setting, the active tectonics of northern Papua New Guinea is dominate by the effects of continuing collision between the Huon– Finisterre island arc terrane with the edge of the Australian continental margin. The overall shortening is concentrated into two zones of thrust faulting, the Ramu–Markham fault zone, which forms the southwestern boundary of the Huon–Finisterre terrane, and the Highlands Thrust Belt, which lies further southwest and deforms the Australian margin. The hanging wall of the Ramu–Markham thrust system is broken up by a series ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

September 2002 Events In Oceania
September is the ninth month of the year in both the Julian and Gregorian calendars, the third of four months to have a length of 30 days, and the fourth of five months to have a length of fewer than 31 days. September in the Northern Hemisphere and March in the Southern Hemisphere are seasonally equivalent. In the Northern hemisphere, the beginning of the meteorological autumn is on 1 September. In the Southern hemisphere, the beginning of the meteorological spring is on 1 September. September marks the beginning of the ecclesiastical year in the Eastern Orthodox Church. It is the start of the academic year in many countries of the northern hemisphere, in which children go back to school after the summer break, sometimes on the first day of the month. September (from Latin ''septem'', "seven") was originally the seventh of ten months in the oldest known Roman calendar, the calendar of Romulus , with March (Latin ''Martius'') the first month of the year until p ...

Earthquakes In Papua New Guinea
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 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 a tsunami. Earthquakes ca ...

List Of Earthquakes In Papua New Guinea
Earthquakes in Papua New Guinea are due to its location near the geologically-active Pacific Ring of Fire. Overall, the population in this region resides in structures that are a mix of vulnerable and earthquake resistant construction. The predominant vulnerable building types are usually metal, timber and unreinforced brick masonry construction.

Liquefaction
In materials science, liquefaction is a process that generates a liquid from a solid or a gas or that generates a non-liquid phase which behaves in accordance with fluid dynamics. It occurs both naturally and artificially. As an example of the latter, a "major commercial application of liquefaction is the liquefaction of air to allow separation of the constituents, such as oxygen, nitrogen, and the noble gases." Another is the conversion of solid coal into a liquid form usable as a substitute for liquid fuels. Geology In geology, soil liquefaction refers to the process by which water-saturated, unconsolidated sediments are transformed into a substance that acts like a liquid, often in an earthquake. Soil liquefaction was blamed for building collapses in the city of Palu, Indonesia in October 2018. In a related phenomenon, liquefaction of bulk materials in cargo ships may cause a dangerous shift in the load. Physics and chemistry In physics and chemistry, the phase transiti ...

West Sepik
Sandaun Province (formerly West Sepik Province) is the northwesternmost mainland province of Papua New Guinea. It covers an area of 35,920 km2 (13868 m2) and has a population of 248,411 (2011 census). The capital is Vanimo. In July 1998 the area surrounding the town Aitape was hit by an enormous tsunami caused by a Magnitude 7.0 earthquake which killed over 2,000 people. The five villages along the west coast of Vanimo towards the International Border are namely; Lido, Waromo, Yako, Musu and Wutung. Name Sandaun is a Tok Pisin word derived from English "sun down," since the province is located in the west of the country, where the sun sets. The province was formerly named West Sepik Province, for the Sepik River that flows through the province and forms part of the province's southern border. Physical Geography The Sandaun Province has beaches along the northern coast, as well as mountainous areas throughout the province, primarily in the southern area of the province. Seve ...

1998 Papua New Guinea Earthquake
The 1998 Papua New Guinea earthquake occurred on July 17 with a moment magnitude of 7.0 and a maximum Mercalli intensity of VIII (''Severe''). The event occurred on a reverse fault near the north coast region of Papua New Guinea, from the coast near Aitape, and caused a large undersea landslide which caused a tsunami that hit the coast, killing between at least 2,183 and 2,700 people and injuring thousands. Tectonic setting The island of New Guinea lies within the complex zone of collision between the Australian Plate and the Pacific Plate. Within this overall setting, the active tectonics of northern Papua New Guinea is dominate by the effects of continuing collision between the Huon– Finisterre island arc terrane with the edge of the Australian continental margin.
