The Villarica volcano erupted early Tuesday near Pucon, Chile, spewing a towering lava fountain and an ash plume into the sky above the volcano.

The impressive eruption of one of the Chile's most active volcanoes piques the interest and imaginations of many children (and grownups, too). The kid- and adult-friendly Science City at the Tucson Festival of Books will offer a peek into volcanos. 

There will be daily volcano eruptions — not quite as big as Villarica, we are assured — at 11 a.m., 1 p.m. and 3 p.m. March 14 and 15 at the two-day, community and family festival celebrating literacy and learning on the University of Arizona campus.

To learn more about volcano eruptions, head over to see "Volcanic Fun with Elizabeth Rusch" at 10 a.m. March 14 on the Science stage.

Here's the description of Rusch's presentation: "Want to learn the true size of our solar system? Can rocks float? How are craters formed? What actually happens when a volcano erupts? Spend an hour with the award-winning children’s science author as she walks kids of all ages through hands-on demos that answer these questions and more."

Science City will be divided into four themed “neighborhoods,” a concept that was introduced at last year’s festival. There will be hands-on activities and demonstrations in the Science of Everyday Life, Science of Natural World, Science of Tomorrow and Science of You neighborhoods. A Science of Pi zone — March 14 is Super Pi Day — will be featured this year.

There will be about 80 participants and about a bazillion activities, demonstrations, talks, author panels, book signings and presentations.
