Although large earthquakes are rare and the last volcanoes raged off our coast thousands of years ago, New England has a surprising amount of active seismic activity and a geologic landscape full of volcanic remains. Join Jack Loveless, post-doctoral researcher in the Department of Earth & Planetary Sciences at Harvard, to learn how these spectacular natural events occur, handle real volcanic rocks, and see how scientists use new techniques, such as 3-D vision, to understand tectonic movement and forecast earthquakes. This program at the Harvard Museum of Natural History, 26 Oxford Street, Cambridge, will begin at 2 pm on Sunday, January 23, and you can be home before the NFL playoff game begins. Free with museum admission. Call 617-495-3045, or log on to www.hmnh.harvard.edu for more information.
