The Mercalli scale, unlike the more famous Richter scale, doesn't measure the actual energy released by an earthquake but how much effect an earthquake had on a given area, making it poorly suited for measuring earthquakes in sparsely populated areas, but ideal for comparing damage done by various tremors. The Mercalli scale, which has been widely used in earthquake engineering, gives a rating from I to XII, where I is felt only by a very few and XII has near total damage, few or no masonry structures remain standing, and objects are thrown into the air. In 1914 Mercalli burnt to death under suspicious circumstances, allegedly after knocking over a paraffin lamp in his bedroom. He is thought to have been working through the night, as he often did (he once was found working at 11 AM when he had set an examination, upon hearing which he replied, "It surely can't be daylight yet "), when the fatal accident occurred.
