Global liquefaction susceptibility map

This is a global liquefaction susceptibility map (EPSG:4326) based on the geospatial liquefaction prediction models of Zhu et al.^[1] . The coastal model was applied for areas <20km from the coast. The inland model was applied elsewhere. Refer to Zhu et al. ^[1] in the first instance for further methodology and descriptions. Input data used in part, or their entirety may comprise (amongst others): rivers ^[2-4] depth to ground water ^[5] precipitation ^[6] land ^[7] V_s30 ^[8] Cell values are based on Zhu et al. ^[1] susceptibility classes where: very low, low, moderate, high, very high 0 refers to no data -- typically water bodies. While this data may be useful as preliminary information for regional-scale planning, a PGV intensity term is required for probability maps. Again, see Zhu et al. ^[1] for a discussion here. An application using this dataset is seen in Koks et al. ^[9]. ^[1] Zhu et al. (2017) An updated geospatial liquefaction model for global application. Bull. Seismol. Soc.
