New Seismic Exposure Model for Guatemala City, a New Seismic Risk Approach

Description: 

Advances in seismic hazards in the Central American region have shown the need to develop new studies on the seismic vulnerability of all cities in the region. In recent years, a series of large magnitude earthquakes have occurred in Guatemala that has highlighted the lack of earthquake prevention and mitigation policies. In 2012 and 2017, two earthquakes of 7.3 and 7.0 respectively occurred in the San Marcos region in the southwest of the country, producing severe damage. Seismic vulnerability studies such as GEM (2018) and PREPARE (2021) have been developed for the country. This study proposes a new seismic exposure model for Guatemala City. A methodology is presented combining different sources of information and using new digital tools for data collection in the country. This exposure model has revealed the high level of buildings vulnerable to a possible large earthquake. Likewise, the results of the exposure model reveal some deficiencies in the prevention and mitigation plans of local public institutions.
