Although the rate of subduction varies little along the entire arc, there are complex changes in the geologic processes along the subduction zone that dramatically influence volcanic activity, crustal deformation, earthquake generation and occurrence all along the western edge of South America.Most of the large earthquakes in South America are constrained to shallow depths of 0 to 70 km resulting from both crustal and interplate deformation.
More than 6,000 people were severely injured. A relative kisses a photo of Kexly Valentino attached to her coffin in Montecristi on April 19.

"In a race to help residents, Ecuador deployed 10,000 soldiers and 4,600 police officers to the affected areas. The convergence associated with this subduction process is responsible for the uplift of the Andes Mountains, and for the active volcanic chain present along much of this deformation front. Although the South America plate exhibits a chain of active volcanism resulting from the subduction andSatellites help link Texas earthquakes to wastewater injection, scientists sayOld evidence leads to new ideas about earthquake hazards in Pacific NorthwestMachine-learning earthquake prediction in lab shows promise (©2016 World Vision/photo by Diego Rivadeneira)Children play in a World Vision Child-Friendly Space in Portoviejo. The earthquake hit Saturday around 7 p.m. while people were going about their evening. Three segments are characterized by steeply dipping subduction; the other two by near-horizontal subduction. The tremors buckled overpasses trapping drivers. If you felt this earthquake, report your experience on the “USGS Did You Feel It?” website for this event. An exception to this was the 1994 Bolivian earthquake in northwestern Bolivia. "Everybody in my neighborhood was screaming saying it was going to be the end of the world." The earthquake was presaged by a magnitude 4.8 foreshock eleven minutes before the main quake struck,At least 676 people were killed and more than 16,600 others were injured in the earthquake.The number of fatalities was estimated as several hundred within thirty minutes of the earthquake.By April 24, the fatality count had reached 654, and 8,340 had been reported as injured.The extent of the rupture can sometimes be known from aftershocks during the few hours following the main shock. The Nazca plate beneath northern Ecuador, southern Peru to northern Chile, and southern Chile descend into the mantle at angles of 25° to 30°. "People looking for family and friends frantically dug with their hands and tools until excavation equipment arrived. Instead, deep earthquakes in this region occur at depths of 500 to 650 km and are concentrated into two zones: one that runs beneath the Peru-Brazil border and another that extends from central Bolivia to central Argentina. "Let's pray for those populations, and for those of Japan, where as well there has been some earthquakes in the last days. Since 1900, numerous magnitude 8 or larger earthquakes have occurred on this subduction zone interface that were followed by devastating tsunamis, including the 1960 M9.5 earthquake in southern Chile, the largest instrumentally recorded earthquake in the world.
Ecuador earthquake: what we know so far At least 350 people have been killed and thousands injured by an earthquake that hit Ecuador on Saturday night. For estimates of casualties and damage, visit the USGS Prompt Assessment of Global Earthquakes for Response (PAGER) website.

Evangelical Council for Financial Accountability Damage is seen inside a store in Guayaquil on April 16. At the location of the earthquake, the Nazca plate subducts eastward beneath the South America plate at a velocity of 61 mm/yr. The elderly woman was injured when a column fell on her. We are proud to be reviewed and held accountable by these independent third-party organizations:World Vision Inc. is a registered 501(c)3 nonprofit organization. Events of the size of the April 16, 2016 earthquake are typically about 160×60 km in size (length x width).Ecuador has a history of large subduction zone related earthquakes.
