How about an LNG bunkering facility in Naples, near the Campi Flegrei volcano? Maybe you start with a minor eruption/earthquake, and the LNG disaster breaches a larger magma chamber to cause a larger eruption? Then you can blanket Europe in ash and start up the typical disaster movie plot, where you follow the Chicken Little and their family as they try to escape the disaster radius.
