1979 Tumaco Earthquake
The 1979 Tumaco earthquake occurred at on 12 December with a moment magnitude of 8.2 and a maximum Mercalli intensity of IX (''Violent''). The epicenter was just offshore from the border between Ecuador and Colombia, near the port city of Tumaco. It triggered a major tsunami, which was responsible for most of the estimated 300–600 deaths. The hardest hit area was Colombia's Nariño Department. Tectonic setting Coastal parts of Ecuador and southern Colombia lie above the convergent boundary where the Malpelo Plate subducts beneath the South American Plate along the Colombia–Ecuador Trench. At this location the Malpelo Plate, the microplate northeast of the Nazca Plate, is moving to the east relative to South America at a rate of 58 mm per year. North of the Carnegie Ridge, the subduction interface has four recognisable segments, from south to north, the Esmeraldas, Manglares, Tumaco and Patia segments. This plate boundary has been the location of several great histori ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megathrust Earthquake
Megathrust earthquakes occur at convergent plate boundaries, where one tectonic plate is forced underneath another. The earthquakes are caused by slip along the thrust fault that forms the contact between the two plates. These interplate earthquakes are the planet's most powerful, with moment magnitudes (''Mw'') that can exceed 9.0. Since 1900, all earthquakes of magnitude 9.0 or greater have been megathrust earthquakes. The thrust faults responsible for megathrust earthquakes often lie at the bottom of oceanic trenches; in such cases, the earthquakes can abruptly displace the sea floor over a large area. As a result, megathrust earthquakes often generate tsunamis that are considerably more destructive than the earthquakes themselves. Teletsunamis can cross ocean basins to devastate areas far from the original earthquake. Terminology and mechanism The term ''megathrust'' refers to an extremely large thrust fault, typically formed at the plate interface along a subduction zone ...

1942 Ecuador Earthquake
The 1942 Ecuador earthquake or the Guayaquil earthquake occurred on 13 May at 9:06 or 9:13 pm local time with a moment magnitude of 7.9. The temblor struck the coastal ( Esmeraldas) region of Manabí Province, Ecuador. It caused damage mainly to cities like Guayaquil, Portoviejo and Guaranda. More than 300 people were killed and the total cost of damage was about US$2.5 million (1942 rate). Ecuador's largest city Guayaquil was the most affected despite the significant distantce from the epicenter. Many reinforced concrete structures in a particular area in the city were completely destroyed, contributing to fatalities. Tectonic setting The Nazca Plate dives beneath the South American Plate along a convergent plate boundary stretching from Colombia to Chile in a process known as subduction. This plate boundary occasionally produces large megathrust earthquakes along the west coast of South America. The Ecuador–Colombia subduction zone occupies part of this plate boundary, wh ...

Earthquake-resistant Structures
Earthquake-resistant or aseismic structures are designed to protect buildings to some or greater extent from earthquakes. While no structure can be entirely immune to damage from earthquakes, the goal of earthquake-resistant construction is to erect structures that fare better during seismic activity than their conventional counterparts. According to building codes, earthquake-resistant structures are intended to withstand the largest earthquake of a certain probability that is likely to occur at their location. This means the loss of life should be minimized by preventing collapse of the buildings for rare earthquakes while the loss of the functionality should be limited for more frequent ones. To combat earthquake destruction, the only method available to ancient architects was to build their landmark structures to last, often by making them excessively stiff and strong. Currently, there are several design philosophies in earthquake engineering, making use of experimental r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1983 Popayán Earthquake
The 1983 Popayán earthquake ( es, El Terremoto de Popayán) occurred on 31 March in Popayán, Colombia.
