Santorini is a beautiful island in Greece. Many people visit Santorini for holidays. But under the island, there is a big volcano. Sometimes, the volcano can make earthquakes and eruptions. Scientists want to know if the volcano is dangerous.

A group of scientists go on a ship to study the volcano. They use a robot to look under the sea. The robot takes pictures and brings back rocks. The scientists look at the rocks and water to learn more about the volcano. They want to help people stay safe.

Some people are afraid when there are earthquakes. Many people left the island when the earthquakes started. Some tourists also cancelled their trips. But some people still come to Santorini. The scientists hope their work will help everyone feel safe on the island.
