You can create your own dataset with google search tools. The tools are for quickly searching and picking up the desired failure images. Unfortunetely i do not know about any other database.

ImageNet has some categories as architectures or buildings.

Also, the NOAA has some natural hazards image you may want to look at. https://www.ngdc.noaa.gov/hazardimages/#/

Google Street View has actually a lot of building images and you can generate tons of it. However, if you're looking for destroyed buildings after earthquakes, I don't think there are many of those. Nevertheless you can still use Google Image given the keywords:
