Okay kiddo, do you know what a volcano is? It's like a mountain that can explode and shoot out hot rocks, ash and lava.
The Global Volcanism Program (GVP) is a group of people who study volcanoes all over the world. They work together to keep track of all the volcanoes, and then they share all the information with everyone else.
The GVP is like a giant library. They keep records of when a volcano erupted, how big the eruption was, and what kind of rocks and ash came out. They also keep track of things like earthquakes and changes in temperature, because those can sometimes be signs that a volcano might erupt soon.
Scientists from all over the world contribute their knowledge to the GVP, so everyone can learn more about volcanoes. The GVP puts all of this information online, so people can use it to study volcanoes, to prepare for possible future eruptions, and to keep people safe.
So that's what the Global Volcanism Program is all about, kiddo. A group of scientists who study volcanoes and share their knowledge with everyone else, to help keep people safe.
