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.

Pacific Ring Of Fire
The Ring of Fire (also known as the Pacific Ring of Fire, the Rim of Fire, the Girdle of Fire or the Circum-Pacific belt) is a region around much of the rim of the Pacific Ocean where many Types of volcanic eruptions, volcanic eruptions and earthquakes occur. The Ring of Fire is a Horseshoe, horseshoe-shaped belt about long and up to about wide. The Ring of Fire includes the Pacific coasts of South America, North America and Kamchatka, and some islands in the western Pacific Ocean. Although there is consensus among geologists about almost all areas which are included in the Ring of Fire, they disagree about the inclusion or exclusion of a few areas, for example, the Antarctic Peninsula and western Indonesia. The Ring of Fire is a direct result of plate tectonics: specifically the movement, collision and destruction of lithosphere, lithospheric plates (e.g. the Pacific Plate) under and around the Pacific Ocean. The collisions have created a nearly continuous series of subdu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aitape
Aitape is a small town of about 18,000 people on the north coast of Papua New Guinea in the Sandaun Province. It is a coastal settlement that is almost equidistant from the provincial capitals of Wewak and Vanimo, and marks the midpoint of the highway between these two capitals. Aitape has 240 V power (in general 24 hours), telephone, a bank, a post-office, a courthouse and a police station, a supermarket and many tradestores, a petrol station, two airstrips, two secondary schools, a mission office and a hospital. Aitape was established as a train station by German colonists in 1905 as part of German New Guinea. During the Second World War the town was occupied by the Imperial Japanese Army. Transport Aitape can be reached by logging road from Vanimo and Wewak (180 km). Boats also leave Aitape Harbor to Vanimo and Wewak. There are two airstrips: Tadji Airport, Tadji (TAJ), where most flights land, and Aitape Airport, Aitape (ATP). Tadji airstrip is located 10 km eas ...

1970 New Guinea Earthquake
On October 31 at 17:53 UTC (November 1 at 03:53 AEST) the island of New Guinea was shaken by an earthquake of magnitude 6.9 that particularly affected the city of Madang on the north coast of Papua New Guinea. Causing between five and eighteen fatalities, it triggered landslides that ran down steep hills into poorly reinforced wooden huts. The area that experienced the most powerful intensity extended out from the epicenter. Underwater landslides caused minor tsunami over about 100 km of coast and severed underwater cables in several places. 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 faulti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solomon Islands
Solomon Islands is an island country consisting of six major islands and over 900 smaller islands in Oceania, to the east of Papua New Guinea and north-west of Vanuatu. It has a land area of , and a population of approx. 700,000. Its capital, Honiara, is located on the largest island, Guadalcanal. The country takes its name from the wider area of the Solomon Islands (archipelago), which is a collection of Melanesian islands that also includes the Autonomous Region of Bougainville (currently a part of Papua New Guinea), but excludes the Santa Cruz Islands. The islands have been settled since at least some time between 30,000 and 28,800 BCE, with later waves of migrants, notably the Lapita people, mixing and producing the modern indigenous Solomon Islanders population. In 1568, the Spanish navigator Álvaro de Mendaña was the first European to visit them. Though not named by Mendaña, it is believed that the islands were called ''"the Solomons"'' by those who later receiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Papua New Guinea
Papua New Guinea (abbreviated PNG; , ; tpi, Papua Niugini; ho, Papua Niu Gini), officially the Independent State of Papua New Guinea ( tpi, Independen Stet bilong Papua Niugini; ho, Independen Stet bilong Papua Niu Gini), is a country in Oceania that comprises the eastern half of the island of New Guinea and its offshore islands in Melanesia (a region of the southwestern Pacific Ocean north of Australia). Its capital, located along its southeastern coast, is Port Moresby. The country is the world's third largest island country, with an area of . At the national level, after being ruled by three external powers since 1884, including nearly 60 years of Australian administration starting during World War I, Papua New Guinea established its sovereignty in 1975. It became an independent Commonwealth realm in 1975 with Elizabeth II as its queen. It also became a member of the Commonwealth of Nations in its own right.

1971 Solomon Islands Earthquakes
The 1971 Solomon Islands earthquakes occurred in the northern part of the Solomon Islands, within Papua New Guinea as a doublet earthquake. The first large shock occurred on July 14 at 06:11 UTC with a magnitude of 8.0. The second large event occurred on July 26 at 01:23 UTC with a magnitude of 8.1. The initial event on July 14 caused a tsunami, which was observed in Rabaul. The earthquake of July 26 triggered a tsunami with a runup in New Britain. Shallow, large thrust earthquakes in the Solomon Islands tend to occur in multiplets. Examples of such earthquakes include the doublets occurred in 1971, 1974, and 1975. The 1971 doublet occurred at the junction of two trenches. The July 14 earthquake is located in the northwestern Solomon Islands Trench, while the July 26 earthquake ruptured the northeastern New Britain Trench. The July 14 earthquake and the July 26 earthquake were caused by the subduction of the Solomon Sea Plate beneath the Pacific Plate and the Bismark Sea Plate, ...

Karkar Island
Karkar Island is an oval-shaped volcanic island located in the Bismarck Sea, about 30 kilometres off the north coast of mainland Papua New Guinea in Madang Province, from which it is separated by the Isumrud Strait. The island is about 25 km in length and 19 km in width. In the centre is an active volcano with two nested calderas. Geography The land is covered with the volcanic andesitic lava. The soil is very fertile and used for growing food crop and cash crop. The island is full of betel-nut, mustard plant and lime. The island is also known for the view from the mountain looking down to Madang town. The latest eruptions on this island occurred in the 1970s. The 1974–1975 eruption produced a large volume of lava which covered almost 70% of the inner caldera's floor, while 1979 produced no lava flow, but killed the two volcanologists, Robin Cooke and Elias Ravian. The volcano erupted as recently as February 26, 2013. The population of approximately 70,000 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surface Wave Magnitude
The surface wave magnitude (M_s) scale is one of the magnitude scales used in seismology to describe the size of an earthquake. It is based on measurements of Rayleigh surface waves that travel along the uppermost layers of the Earth. This magnitude scale is related to the local magnitude scale proposed by Charles Francis Richter in 1935, with modifications from both Richter and Beno Gutenberg throughout the 1940s and 1950s. It is currently used in People's Republic of China as a national standard (GB 17740-1999) for categorising earthquakes. Recorded magnitudes of earthquakes through the mid 20th century, commonly attributed to Richter, could be either M_s or M_L. Definition The formula to calculate surface wave magnitude is: :M_s = \log_\left(\frac\right)_ + \sigma(\Delta)\,, where A is the maximum particle displacement in surface waves (vector sum of the two horizontal displacements) in μm, T is the corresponding period in s (usually 20 2 seconds), Δ is the epi ...

1993 Finisterre Earthquakes
The 1993 Finisterre Range earthquakes occurred in October 1993, beneath the Finisterre Range, north of Markham Valley in Morobe Province, Papua New Guinea. The earthquake sequence began on October 13 with a 6.9 mainshock, followed by 6.5 and 6.7 mainshocks. The complex earthquake sequence seriously damaged many villages in the rural Eastern Papua New Guinea region, generating landslides and killing at least 60 people. Tectonic setting Papua New Guinea is situated in a region where the Pacific, Australian, Caroline and several microplates are converging. At the Huon Peninsula, the Woodlark Plate is moving north, converging beneath the South Bismarck Plate along the Markham Valley. The tectonic motion forms a complex zone of subduction and continental collision zones which affect the region. Due to the location at a major plate boundary zone, Papua New Guinea is struck by earthquakes and tsunamis frequently and is one of the world's most seismically active regions. The Finiste ...

Tsunami
A tsunami ( ; from ja, 津波, lit=harbour wave, ) is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake. Earthquakes, volcanic eruptions and other underwater explosions (including detonations, landslides, glacier calvings, meteorite impacts and other disturbances) above or below water all have the potential to generate a tsunami. Unlike normal ocean waves, which are generated by wind, or tides, which are in turn generated by the gravitational pull of the Moon and the Sun, a tsunami is generated by the displacement of water from a large event. Tsunami waves do not resemble normal undersea currents or sea waves because their wavelength is far longer. Rather than appearing as a breaking wave, a tsunami may instead initially resemble a rapidly rising tide. For this reason, it is often referred to as a tidal wave, although this usage is not favoured by the scientific community because it might give ...
