This document discusses volcano hazards and appropriate measures before, during, and after volcanic eruptions. It begins by outlining signs of an impending eruption such as increased seismic activity and gas emissions. It then discusses volcano hazard maps and appropriate preparedness, response, and recovery measures. These include having emergency supplies ready before an eruption, seeking shelter and wearing masks during, and cleaning ash after while awaiting further instructions. The document provides references to online images and sources of additional information about volcanoes and their impacts.
