Catania is the second largest city in Sicily, and is known for it’s seismic history! Yikes!! Our tour guide said that in her lifetime, she has seen the city rebuilt five times. All of the citizens live beneath the active eruptions of Mt. Etna volcano, never knowing if the next eruption is going to take their house. It is one of the most active volcanos in the world and is in a constant state of activity. It has been designated as a decade volcano by the United Nations, and is also a UNESCO world heritage site. Of late, it has erupted in 2001, ’03, ’05, & ’08, with summit eruptions in 2006, ’08, and 2012. Interesting to see, but I sure wouldn’t want to live here!
