ESA (European Space Agency) has news: a volcanic region in southern Italy is showing increased signs of unrest.

Images from the Envisat satellite show that the Phlegrean Fields or "burning fields" caldera, an area about 8 miles (13 km) across, is entering a period of uplift: a slight uplift of 2.8 centimeters (a little more than an inch) since 2005.

That doesn't seem much, but it's worth a second look. The caldera last erupted in 1538, but it's begun to be more active in the past few years. And there are people living in the area. The greatest ground deformation is in the center of the beautiful town of Pozzuoli, near the caldera's center.
 
Yes, there are lots of people living in this volcanically active caldera. In fact, lots of tourists go to Pozzuoli, sit at cafes, hike around the caldera, and go swimming. Some of you might think it's stupid to live in a volcanic area that's 8 miles wide, but if you think about it, living in a caldera makes as much sense as living in Hawaii: the whole island is a volcano. You just have to pay more attention to the geologic news, that's all.
