- Abstract
- The seismic risk study for Guatemala includes the collection and description of geological and seismological environment and the use of that information in developing iso-acceleration maps of Guatemala. Results are given on future probable seismic hazard for Guatemala which can be used by engineers in formulating the seismic codes, by planners in future developments, and by the insurance companies in evaluating the seismic risks and rates. Various state-of-the-art models are used to develop this hazard information. Two types of models were used in developing the seismic hazard maps of the country. The first model was the Poisson occurrence model where the seismic recurrence for various sources was based on past earthquake data and on a hypothesized upper Richter magnitude. These maps are presented for four separate return periods. The Bayesian model, where subjective and objective information on the number of occurrences and the magnitude level is used, is presented. Acceleration zone graphs can be used to evaluate the level of peak ground acceleration as a function of return period.
