Staff Picks: Parking Lot Lava

In a parking lot behind the Comstock Art Facility at Syracuse University, geologist Jeff Karson and sculptor Bob Wysocki cook up something almost unimaginable – homemade lava. Using a gas furnace the size of a small truck, the two professors melt gravel typically used for roadbeds into hot molten rock that they pour onto sand to recreate natural lava flows seen in places like Hawaii, Iceland and Italy.

Songs of the Arches (with Helicopters)

The wind that carved the sandstone of Arches National Park into spectacular arches and towers also plucks them, like giant guitar strings, making them ring at low frequencies. Geoscientist Riley Finnegan and her colleagues in the Geohazards research group at the University of Utah are recording these arch songs in the Park and around Utah with seismometers, the same basic technology geologists use to listen for earthquakes, to learn their characteristic vibration frequencies—and how human noise affects them.

Escape from Thera

About 3,600 years ago, a colossal volcanic eruption blew apart the Greek island Thera, now the popular tourist destination known as Santorini.

But unlike the Roman cities, Akrotiri has a notable lack of bodies.
