Seismic risk map of Colombia Aviso del Terremoto, 1785 The subduction of the Malpelo plate (left) below the North Andes plate (right) causes most of the earthquakes in Colombia. This is a list of earthquakes in Colombia. Colombia is a seismically active country and has a large seismic risk in many areas of its territory due to its location at ...
This produces an increased risk of earthquakes and volcanic eruptions. Some natural disasters of this type are: The 1875 Cúcuta earthquake; The 8.2 M w Tumaco earthquake shook Colombia and Ecuador with a maximum Mercalli intensity of IX (Violent), killing 300–600, and generating a large tsunami. The 1982 Popayán earthquake
PHIVOLCS Observatory at Mount Hibok-Hibok.. The Philippine Institute of Volcanology and Seismology (PHIVOLCS, Filipino:; Filipino: Surian ng Pilipinas sa Bulkanolohiya at Sismolohiya [2]) is a Philippine national institution dedicated to provide information on the activities of volcanoes, earthquakes, and tsunamis, as well as other specialized information and services primarily for the ...
Recent earthquakes that struck Colombia's Pacific coast areas have included one accompanied by a tsunami in Tumaco, Nariño Department, on December 12, 1979, measuring 7.9 on the Richter magnitude scale, the largest in northwestern South America since 1942; another on November 15, 2004, with a magnitude of 6.7; and one on September 10, 2007 ...
Where an earthquake is not recorded on seismographs an isoseismal map showing the intensities felt at different areas can be used to estimate the location and magnitude of the quake. [1] Such maps are also useful for estimating the shaking intensity, and thereby the likely level of damage, to be expected from a future earthquake of similar ...
A powerful earthquake followed by a strong aftershock shook Colombia’s capital and other major cities on Thursday. In the Capital of Colombia, which has a population of 11 million, numerous ...
The location of the first earthquake was in El Calvario, in the department of Meta, 70 km (43 mi) southeast of the country's capital, Bogotá. The depth of the earthquakes were about 10 km (6.2 mi) beneath the surface. [4] Tremors from the earthquakes were strongly felt in Bogotá, with a Modified Mercalli intensity of V (Moderate) reported there.
The PHIVOLCS earthquake intensity scale (PEIS; Filipino: Panukat ng Pagyanig ng Lindol) [1] is a seismic scale used and developed by the Philippine Institute of Volcanology and Seismology (PHIVOLCS) to measure the intensity of earthquakes. It was developed as upon a specific response to the 1990 Luzon earthquake. PHIVOLCS cites seismic scale ...
