1970 New Guinea earthquake

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 20 km mi 0 us out from the epicenter. Underwater landslides caused minor tsunami over about 100 km of coast and severed underwater cables in several places.http://www.ngdc.noaa.gov/nndc/struts/results?eq_0=4550&t=101650&s=18&d=99,91,95,93&nd=display https://archive.today/20121214070431/http://www.ngdc.noaa.gov/nndc/struts/results?eq_0=4550&t=101650&s=18&d=99,91,95,93&nd=display dead December 14, 2012 Comments for the Tsunami Event NGDC May 14, 2010 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.Abers G.A.

The orientation of these faults, parallel to the direction of thrusting, suggests that they accommodate distortion of the Huon–Finisterre block. Most of the seismicity in northern Papua New Guinea is associated with the Ramu–Markham fault system, with a smaller number of earthquakes occurring on the strike-slip faults and on the Highlands Thrust Belt. Earthquake The earthquake took place near Madang, approximately 350 mi km 0 us northwest of Port Moresby. Generally, it was on the northeast coast.https://news.google.com/newspapers?id=1nYdAAAAIBAJ&pg=2565,108462 Strong Earthquake Hits New Guinea Coast Area Victoria Advocate Publishing Co.

Felt throughout the entire island of New Guinea, it caused extensive damage in the city of Madang, where it killed three people.https://earthquake.usgs.gov/learn/today/index.php?month=10&day=31&submit=View+Date Today in Earthquake History: October 31 December 18, 2009 May 2, 2010 Several homes buckled and cracks appeared in streets.https://news.google.com/newspapers?id=t84VAAAAIBAJ&pg=6346,18439 Earthquake Jolts New Guinea Journal Communications Milwaukee Journal Sentinel November 2, 1970 May 2, 2010July 2026 InternetArchiveBot On the coast of the island, a cable connecting telephone units for Australia and Guam was cut. Initially, officials were worried of a tsunami risk though the earthquake did not produce any. This was due to a dramatic recession of water levels near the epicenter, followed by a rise that at one point measured 3 m ft 0 us.Catalog of tsunamis in the Pacific 1969–1982 https://books.google.com/books?id=umZ--INFYEEC&dq=November+1%2C+1970%3B+03+hr+53+min&pg=PA32 S. L. Soloviev C. N. Go K. Kim 1992 Academy of Sciences of the USSR 32 9780788139314 When a canoe was inverted by this change, three people were killed. Its maximum intensity of VIII (Severe) was restricted to a zone 20 km mi 0 us from the epicenter (including the epicenter). Up to 70 km mi 0 us away from the epicenter, damage measuring intensity VII (Very strong) was recorded. Landslides caused most of the deaths (which the Catalog of Tsunamis in the Pacific, 1969–1982 lists as 15), which occurred in wooden huts damaged by the shock and crushed by rock. The number of huts damaged totaled more than 800. The city most damaged was Madang. Houses with poor earthquake engineering such as those with weakly reinforced frames performed poorly. Forty-five percent of the city's steel water tanks were beyond repair.
