Pliny was persuaded to explore a peculiar cloud formation that appeared to be coming from the summit of the local mountain, Vesuvius. He was duly rowed ashore, visited a local village to calm the panicked inhabitants--and was promptly caught up in a massive eruption. He died of asphyxiation by volcanic gases on August 24, leaving behind him a vast reputation and, as memorial, a single word in the lexicon of modern vulcanology, Plinian. A Plinian eruption is now defined as an almighty, explosive eruption that all but destroys the entire volcano from which it emanates. And the most devastating Plinian event of the modern era occurred 1,804 years, almost to the day, after Pliny the Elder's death: at Krakatoa.)
