Volcanologists are very important people. A volcanologist is a person who studies volcanoes. Though they spend a lot of their time in labs analyzing data (to tell what or where or when this lava was formed) , fieldwork is very important. Volcanologists monitor volcanoes, measure temperatures, and collect samples of lava rock or gases or other small objects that might help them solve the mystery that they are tying to solve. But a volcanologists also has a lot of equipment. They wear a suit that is similar to a space suit with a hard hat and gloves. They wear this so that they can survive the hot temperature. Volcanologists have tape measures to measure distances and height, binoculars to see far away objects, and journals to record information.
