COVER Ash from Mount Sinabung, one of Indonesia's 130 active volcanoes, billows over the Sumatran village of Sukanalu on 13 June 2015. Studies of volcanoes and other natural hazards have yielded better warnings, risk assessments, and disaster response, but dangers remain. A special section beginning on page 230 and online at http://scim.ag/29qQGyL spotlights new tools and ideas for taming nature's fury.
