chile 2015 tsunami

Energy Distribution On September 16, 2015, a Mw 8.3 earthquake occurred off the coast of central Chile, 46 km west of the town of Illapel. A massive 8.3 magnitude earthquake triggering a tsunami stuck off the coast of Chile September 16, 2015. The quake caused a tsunami impacting the coast mainly between the towns of Caldera (c. 27°S) and Pichidangui (c. 32°S). Listed wave heights are maximum Many observatories provide data to the Center; such as the NOAA National Ocean Service, the U. of recorded at tide gages monitored by the National Tsunami Warning Center (NTWC). The assemblage of sedimentary structures indicates rapid deposition, from one or several waves associated with the tsunami event. Tsunamis therefore occur comparatively often in this country. the Pacific Tsunami Warning Center's homepage. At Playa Changa, a beach at Coquimbo affected by the highest waves, the tsunami destroyed large parts of the coastal road embankments on both the seaward and landward sides. On the landward side the tsunami distributed triangular concrete construction elements of the embankment across the coastal plain. the time between data samples. (2016) estimated the 2015 Illapel tsunami energy to be 7.9 x 1013 J using full-wave inversion, conclud- ing that the main excitation of the tsunami had an area of 100–200 km long and 100 km wide close to landward direction in the newly forming upper layer. Cross-beds in the lower four layers indicate deposition from tsunami inflow, cross bedding in the second layer from the top layer records outflow. The earthquake triggered a tsunami which devastated several coastal towns in south-central Chile and damaged the port at Talcahuano.Tsunami warnings were issued in 53 countries, and the wave caused minor damage in the San Diego area of California and in the Tōhoku region of Japan, where damage to the fisheries business was estimated at ¥6.26 billion (US$66.7 million). This synchroneity is indicated by sand sourced from the lower layer which has been preserved as a thin plume deformed in the downcurrent, i.e. per hour, as fast as a jet plane.

Toda la población costera fue evacuada por prevención. The Sample Interval column shows The sedimentary package consists of 6 mostly lenticular layers of variable thickness and spatial extent, ranging between dark laminae a few millimeters thick and rich in heavy minerals, and lighter colored sand layers up to 15 cm thick. According to the USGS, the 16 September 2015 earthquake occurred as a result of thrust faulting on the interface between the Nazca and South America plates in Central Chile. Sand used in construction of the embankment was redistributed across the beach as an outflow deposit.

The quake has damaged regions of Chile, … Grain size distributions are moderately well to well sorted and unimodal with modes between 1.3 and 2.0 Φ (medium sand). Water escape through small volcanoes appears to have been coeval to formation of the overlying layer by traction deposition.

In the open ocean, tsunami waves can travel at speeds up to 800 km per hour or 500 mi. The report also notes ominously that there are "silent areas" in which, so far … The earthquake occurred on thrust faults along the boundary of the Nazca and South American plates. Las olas de mayor tamaño, de hasta cinco metros, se registraron en el … The 2010 Chile earthquake occurred off the Maule coast of central Chile on Saturday, 27 February 2010, at 03:34 local time, having a magnitude of 8.8 on the moment magnitude scale, with intense shaking lasting for nearly four minutes.
