Exploring Earth: Is It Safe to Live Near a Volcano?
You might not remember what you were doing on May 18, 1980, but I remember hearing on the radio that morning that Mount. St. Helens had erupted, wondering what that would mean for my family and me, and watching ash falling like rain from the sky just six hours later. We live 300 miles east of the volcano, and the fine ash from that eruption covered our city and shut it down for a week. The primary focus of this excellent interactive site is for you to decide how to plan for evacuation when a volcanic eruption is imminent. You can examine volcanic deposits from prior eruptions, see an interesting time-lapse video of the eruption alongside a cross-section of the volcano showing what was happening inside the mountain, and find out what the actual area affected by the eruption. As you go step by step through the scenarios, there are questions posed for you to consider for potential evacuation plans.

New York Times Book Review: A Literary Map of Manhattan
What an interesting way to explore Manhattan and its place in American literary history. Scroll down the map of the island or click on the book icons to find quotations from nearly one hundred authors that relate to specific addresses on Manhattan. You’ll find the quotation, citation to the work that contains the quotation, and, often, a portrait of the author. You can also access an index of the authors and titles if you are looking for a specific book. References from early 19th century to contemporary fiction, children’s books, and poetry dot the landscape.
