The highest and lowest ranked causes are highlighted when the chart loads. These represent the cumulative ranking across all years. Lightning, a natural cause, often floats to the top, but that’s only because on the human side, the vote is split between more than twenty options. Lightning doesn’t predominate in all states, though. In Alabama, the number one cause is pyromania. In Indiana, it’s brakeshoes. In Minnesota, it’s field burning. There are a couple of overall trends, too. Smoking is going down as a cause, and powerlines are going up.
Floods, fires, earthquakes, volcanoes, bombings, droughts, and even alien invasions: disaster can take many forms. And, although disasters are always felt dramatically, a disaster’s form and location impacts who records its effects and what forms those records take. “Where Disaster Strikes” investigates the intertwined categories of modern space and disaster through the Harvard Map Collection’s maps of large destructive events from the London Fire to the present.
