The 1995 Colima–Jalisco earthquake occurred on October 9 at 15:35 UTC with a moment magnitude of 8.0 and a maximum Mercalli intensity of VIII (Severe). The shock occurred off the coast of Jalisco, Mexico, where a tsunami was triggered that affected a 200 km on stretch of the coast.http://www.ngdc.noaa.gov/nndc/struts/results?eq_0=5423&t=101650&s=18&d=99,91,95,93&nd=display https://web.archive.org/web/20200901014559/https://www.ngdc.noaa.gov/nndc/struts/results?eq_0=5423&t=101650&s=18&d=99,91,95,93&nd=display dead September 1, 2020 Comments for this tsunami event NGDC 13 March 2010 The earthquake could be felt in Mexico City and in high-rise buildings in Dallas and Houston.https://earthquake.usgs.gov/earthquakes/eqarchives/significant/sig_1995.php Significant earthquakes of the World, 1995 United States Geological Survey 13 March 2010 dead https://web.archive.org/web/20110608020600/http://earthquake.usgs.gov/earthquakes/eqarchives/significant/sig_1995.php 8 June 2011 In Mexico, the Cihuatlan-Manzanillo was the most severely affected area. At least 49 people died and 100 were injured.
Tectonic setting
This earthquake occurred in the area where the Rivera plate subducts beneath the North American plate.Zobin V.M.

Damage
Although the tsunami affected a 200 km stretch of coast, severe damage was confined to areas with shallow shoreline topography. Most of the flooding occurred in the Tenacatita Bay area. Landslides blocked roads between Guadalajara and Manzanillo. In Manzanillo, 18 people died in the collapse of an eight-story hotel.Death toll rising after earthquake in Mexico https://www.baltimoresun.com/2003/01/23/death-toll-rising-after-earthquake-in-mexico/ January 23, 2003 New York Times News Service The Baltimore Sun 2011-12-20
Characteristics
Earthquake
The earthquake rupture lasted for about a minute and involved a 200 km long break along the plate boundary. The greatest displacement of the fault is about 5 m.http://www.usc.edu/dept/tsunamis/manzanillo/ The Manzanillo Earthquake 2010-03-13 dead https://web.archive.org/web/20110528024610/http://www.usc.edu/dept/tsunamis/manzanillo/ 2011-05-28 A 14 cm subsidence occurred at Manzanillo.
The variations in observed seismic intensity indicate that three asperities were ruptured during this event.
Tsunami
The tsunami had a maximum run-up height of 5.1 m. There were at least two waves recorded. The tsunami was also observed in Ecuador, French Polynesia, Samoan Islands, Australia and Hawaii.
Postseismic moment release
The aftershocks of this earthquake marked a rectangular region of about 170 km by 70 km.Pacheco J. Singh K. Domínguez J. Hurtado A. Quinanar L. Jiménez Z. Yamamoto J. Gutiérrez C. Santoyo M. Bandy W.

If the postseismic moment release up to about two weeks after the main shock is included, it will be equivalent to 35% of that of the main shock, which will make the additional seismic moment equivalent to that of an w y 7.7 earthquake.http://www.geodesy.cwu.edu/about/pubs/melbourne/Melbourne_WebbEA_Postseis.pdf Rapid postseismic transients in subduction zones from continuous GPS Journal of Geophysical Research: Solid Earth 107 B10 ETG 10–1 2002 Melbourne Timothy I Webb Frank H Stock Joann M Joann Stock Reigber Christoph 2002JGRB..107.2241M 10.1029/2001JB000555 free
