AbstractWe present a geotechnical map of Gran Canaria (Canary Islands, Spain) based on the laboratory and field characterization of 344 samples collected in the main 7 islands of the Archipelago. The map is obtained grouping the 109 lithologies of the official geological map into 7 geotechnical classes, taking into account the value of the uniaxial compressive strength of the intact rock. The new map shows a majority of hard and very hard rocks, which is consistent with the intra-plate volcanic geology of the island. As an application of the geotechnical map, and taking into account that rockfalls represent a severe threat in Gran Canaria, we develop a rockfall-runout map by applying STONE, a three-dimensional simulation program that generates simple colour maps useful to assess rockfall hazard. The accuracy of the simulation depends on the appropriate identification of the friction and energy restitution coefficients, which are derived from the geotechnical map and calibrated using two well-known rockfall cases occurred in the island. The runout map provides useful information at regional scale to evaluate and mitigate rockfall hazards, and represent a replicable application in other volcanic environments.
