Recent research from MS Amlin shows that insurers may be significantly underestimating earthquake risk (by up to 60% in extreme cases) because models fail to capture the effects of little-known “supershear” earthquakes. According to the study, two-thirds of insured losses from seismic events over the past decade were caused by destructive supershear ruptures, causing losses…
