A device or instrument used to measure the severity or extent of a disaster or damage.
From disaster + -meter (from Latin metrum, 'measure'). This is a technical neologism combining Greek/Latin roots, likely from 19th-century scientific terminology.
While 'disastimeter' sounds like a scientific instrument, it's actually quite rare and mostly appears in academic or specialized technical writing—it's the kind of word that linguists love because it shows how English can build new words by combining existing roots.
