The earthquake occurred as the result of reverse faulting at an intermediate depth. At the location of the earthquake, some researchers consider the edges of the Australia and Pacific plates to be divided into several microplates that take up the overall convergence between Australia and the Pacific, including the Solomon Sea and South Bismark microplates local to this event. Updated 11:38 AM ET, Sat December 17, 2016. CNN's Joe Sutton, Jennifer Deaton and Sheena McKenzie contributed to this report. Pub refusing to serve man with autism prompts plea for greater awareness of disability, Jill Biden has experienced tragedy first hand. The American Meteor Society (AMS) received more than 210 reports from 12 states, including Massachusetts,... Major floods hit parts of southern Andalusia, Spain, on Thursday, November 5, 2020, resulting in damage, blocked roads, trapped residents, and a derailed train. The extent of damage was not immediately known. Tsunami warnings have been canceled after a 7.9 magnitude earthquake struck in the sea off Papua New Guinea on Saturday night. Geoscience Australia is reporting M8.0 at a depth of 95 km (59 miles). The major tremor initially triggered a more widespread tsunami warning for the Pacific region, including New Zealand, Indonesia, Nauru and the Solomon Islands, but that was pulled back after the US Geological Survey (USGS) downgraded the magnitude slightly from 8. There are about 23 877 people living within 100 km (62 miles). Tremors in this part of the world are fairly common, and earlier this month a magnitude 7.8 earthquake also. First witness reports mention shaking lasting up to 4 minutes. 33 M7.5+ earthquakes have been recorded since 1900, including three shallow thrust fault M8.1 events in 1906, 1919, and 2007. Reverse-faulting events of the size of the December 17, 2016, M 7.9 earthquake are typically about 135x60 km (length x width). Victoria has announced free kindergarten for 2021. Aftershocks map, last updated at 12:20 UTC. Posted by TW on December 17, 2016 at 12:04 UTC (3 years ago) Categories: Featured articles, Seismic activity, Tsunami. Heavy, significant snow accompanied by strong northwesterly winds resulted in dangerous commute conditions in parts of Atlantic Canada on Tuesday and Wednesday, November 3 and 4, 2020. Intermediate-depth earthquakes represent deformation within subducted slabs rather than at the shallow plate interface between subducting and overriding tectonic plates. Most of the large and great earthquakes east of New Guinea are related to this subduction; such earthquakes are particularly concentrated at the cusp of the trench south of New Ireland. If you value what we do here, please consider subscribing today. ET), the US Geological Survey said. The quake struck in the ocean about 45 kilometers east of Papua New Guinea's New Ireland island, also known as Latangai, at about 8:51 p.m. (5:51 a.m. At the location of the earthquake, the Australia plate converges with and subducts beneath the Pacific plate at a rate of about 105 mm per year towards the east-northeast. A nurse at Buka General Hospital in Bougainville said the quake was so strong it felt like the building she was sleeping in would topple — she said patients were being moved a few kilometres to higher ground. The location, depth, and focal mechanism solutions of the December 17th event are consistent with its occurrence within the interior of the subducted Australia plate lithosphere, rather than on the shallow thrust interface between these two plates. Geoscience Australia is reporting M8.0 at a depth of 95 km (59 miles). The plate boundary between the Australia and Pacific plates in the Papua New Guinea region is very active seismically; 26 M 7+ events have occurred within 250 km of the May 7, 2015, earthquake … A more detailed examination of the seismic zone along it's eastern segment reveals a gap in intermediate depth seismicity under Timor and seismic mechanisms that indicate an eastward propagating tear in the descending slab as the negatively buoyant oceanic lithosphere detaches from positively buoyant continental lithosphere. People living along Papua New Guinea's coastline fled to higher ground after a magnitude-7.9 earthquake struck east of the Pacific nation, triggering a tsunami warning for parts of the archipelago. Recent earthquakes in this area have caused secondary hazards such as tsunamis and landslides that might have contributed to losses. Which tectonic plates were involved during this earthquake? According to the USGS, the epicenter was located 132.8 km (82.5 mi) E of Kokopo (population 26 273) and 302.0 km (187.7 mi) NW of Arawa (population 40 266), Papua New Guinea. They typically cause less damage on the ground surface above their foci than is the case with similar-magnitude shallow-focus earthquakes, but large intermediate-depth earthquakes may be felt at great distance from their epicenters. Some casualties and damage are possible and the impact should be relatively localized. Overall, the population in this region resides in structures that are vulnerable to earthquake shaking, though some resistant structures exist. How did the plates move? June 8 - Police open fire on student protesters at the University of Papua New Guinea in Port Moresby, protesting against Prime Minister Peter O'Neill, killing four and leaving another seven injured. "The town residents have vacated the whole place, those in the villages live higher up, so they're okay, it's just those near the coast," local resident Christabel Biasu said. USGS issued a yellow alert for shaking-related fatalities and economic losses. The Australia-Pacific plate boundary is over 4000 km long on the northern margin, from the Sunda (Java) trench in the west to the Solomon Islands in the east. Producing content you read on this website takes a lot of time, effort, and hard work. Tsunami waves reaching 1 to 3 meters (3.3 to 9.8 feet) above the tide level are possible along some coasts of Papua New Guinea. Here, the Australia-Pacific plate relative velocity is approximately 110 mm/yr towards the northeast, leading to the 2-8 mm/yr uplift of the New Guinea Highlands. Tsunami is possible along some coasts of Papua New Guinea. PAGASA declared the system as a tropical depression at 12:00 UTC on November 7 and assigned it the name Tonyo. Over the intervening 8 days, 45 earthquakes of M 4.5+ occurred nearby, including a M 6.6 event about 12 hours before the April 19th earthquake. There were no immediate reports of damage or casualties from the quake, which the USGS initially measured at magnitude-8.0 and at a depth of about 100 kilometres. How will it work? Contrary to earlier tectonic models in which this trough was interpreted as a subduction feature continuous with the Sunda subduction zone, it is now thought to represent a subsiding deformational feature related to the collision of the Australia plate continental margin and the volcanic arc of the Eurasia plate, initiating in the last 5-8 Myr. On April 1, 2007, a M8.1 interplate megathrust earthquake occurred at the western end of the trench, generating a tsunami and killing at least 40 people. Papua New Guinea is along the "Ring of Fire," a zone of seismic activity and volcanoes around the edges of the Pacific Ocean. Alun Beck, owner of the Treehouse Village Resort on the island of New Ireland, told CNN he didn't feel anything and was setting up fishing boats to go shark fishing when the earthquake hit. This was the third M8.1 megathrust event associated with this subduction zone in the past century; the other two occurred in 1939 and 1977. Such hazards often lead to collapse of built-up infrastructures like roads, bridges, buildings apart from inflicting heavy toll on human life and properties. During the same period, ongoing activity was reported for 12 volcanoes. Many residents in the northern parts of the autonomous region of Bougainville sought higher ground amid warnings that tsunami waves were possible. Tectonism induced Tsunami, fire, landslide along with the tremor-triggered-liquefaction are the common hazards experienced worldwide. The western portion of the northern Australia plate boundary extends approximately 4800 km from New Guinea to Sumatra and primarily separates Australia from the Eurasia plate, including the Sunda block. Bright fireball over Connecticut and New York, U.S. Newly-discovered asteroid 2020 VW flew past Earth at 0.58 LD. … The westernmost of these is the Birds Head Peninsula microplate in Indonesia's West Papua province, bounded on the south by the Seram trench. The Solomon Sea microplate moves slightly faster and more northeasterly with respect to the Pacific plate (and South Bismark microplate) than does the Australia plate due to sea-floor spreading in the Woodlark Basin several hundred kilometers to the southeast of the December 17th earthquake, facilitating the classic subduction evident beneath New Britain and New Ireland. The December 17th, 2016 earthquake is almost co-located with a M 7.6 event in September 2005, with a similar faulting mechanism. Along the South Solomon trench, the Australia plate converges with the Pacific plate at a rate of approximately 95 mm/yr towards the east-northeast. The eastern section is over 2300 km long, extending west from northeast of the Australian continent and the Coral Sea until it intersects the east coast of Papua New Guinea. In this context, the event occurred along the boundary between the Solomon Sea and South Bismark microplates." The boundary is dominantly convergent along an arc-continent collision segment spanning the width of New Guinea, but the regions near the edges of the impinging Australia continental margin also include relatively short segments of extensional, strike-slip and convergent deformation. Residents in other parts of Papua New Guinea, including the capital of Port Moresby and Kavieng in the northern tip of New Ireland island, said they had not felt the quake, and no evacuation plans were in place. As of Saturday, November 7, Eta is blamed for the deaths of more than 170 people across Central America. He found out about the quake two hours later via social media and had not heard about major damage. Before collision began, the Sunda subduction zone extended eastward to at least the Kai Islands, evidenced by the presence of a northward-dipping zone of seismicity beneath Timor Leste. The Papua New Guinea region frequently hosts large earthquakes. (USGS) More information on regional seismicity and tectonics. Hazardous tsunamis were initially possible though about midnight local time along some coasts of that country, as well as the Solomon Islands, Pohnpei, Chuuk, Indonesia, Nauru, Kosrae and Vanuatu, the PTWC said. "Deep-focus" earthquakes, those with focal depths greater than 300 km, also occur in the subducted Solomon Sea microplate to the north.
