Abstract
The State of Morelos, in Mexico, has an architectural heritage conformed by 4614 religious and civil buildings, many of which were severely affected by the earthquake that occurred on September 19, 2017, which also caused damages to the built heritage in the states of Puebla, Tlaxcala, Mexico and Mexico City. A total of about 2800 heritage buildings suffered different damages degrees, reaching in many cases the collapse of elements such as vaults, domes, bell towers as well as their cloisters. The Ex-Convent of San Mateo in Atlatlahucan, Morelos, suffered damages on its main nave, in the pinnacles on the longitudinal side walls as well as in the clock box located on the front façade. In the present work, an analysis is made of the damages observed in the building, as well as a preliminary analytical diagnosis of the behavior of the main nave in order to propose future reinforcement actions for the building.
Highlights
The Ex-Convent of San Mateo, Atlatlahucan, was begun in 1535 and completed in 1567 and is part of the eleven convents that integrate the well-known route of the convents
On September 19, 2017 at 13:14:40 local time, a 7.1 magnitude earthquake occurred with an epicenter of coordinates 18.4 North latitude and –98.72 West longitude and a hypocentral depth of 57 km, according to data from the Institute of Geophysics of the Autonomous National University of Mexico, UNAM, (Fig. 2)
Prior to the September 19, 2017 earthquake the barrel vault of the temple had a longitudinal crack in the intrados of the arch key, which seems to be recently been consolidated at the date of the picture (Fig. 5)
Summary
The Ex-Convent of San Mateo, Atlatlahucan, was begun in 1535 and completed in 1567 and is part of the eleven convents that integrate the well-known route of the convents. This building was recognized in 1994 by UNESCO as cultural heritage of the humanity (Fig. 1). The mentioned fault consists in the rupture by traction of the subducted plate at intermediate depths (50-60 Km), occurring in most cases within the earth’s crust (which is why they are known as “intraplate” earthquakes) and at short distances from urban centres.
