Abstract

Seismic hazard assessment requires knowledge of regional geological and geotechnical parameters. Shear wave velocity averaged across the upper 30 m of soil (Vs30) is a key parameter for site response studies in earthquake engineering. In the city of Quito, the capital of Ecuador, seismic data are scarce. This paper combines a recently compiled geotechnical database with a Bayesian Kriging technique to generate new soil geotechnical property maps for the city of Quito. The new QUITO/GEO-299 soil geotechnical database contains 299 records of soil geotechnical test results from across the Quito region. These datapoints were analysed using a Bayesian Kriging approach recently developed for generating seismic hazard data for the Kathmandu Valley in Nepal. The resulting Quito Vs30 map is compared to the corresponding map created using slope-based proxies implemented in the global Vs30 model presented by the U.S. Geological Survey. These new resources are useful for geotechnical engineers working in the Quito region, especially during project planning and preliminary design phases.
