 One of Europe's most active volcanoes is at it again, spewing lava and smoke. Eruptions from one of Mount Etna's craters pushing lava down the 11,000-foot-high volcano in Sicily, the activity forcing a nearby airport to close. Records fell across the West as a slow-moving heat wave of potentially historic proportions tightened its grip from the Pacific Northwest to Arizona. The Southwest and Mid-Atlantic also sweltering with a press of heat and humidity expected to last through Saturday or beyond.
