We do similar for flood insurance. These quakes are not the devastating kind. They range in the <M4 scale, so it'll be mostly toppled chimneys and adornments, perhaps some brick walls might collapse. The damages are typically in the "minor", possibly escalating to "moderate" but not "major", so there would not be armies of lawyers trawling for claimants. But this is still a nuisance which needs to be addressed for property and infrastructure owners as well as an incentive for the industry to find better solutions to disposing drilling water byproducts.
