Final answer:
The subject of this question is geography. Living near an active volcano can be risky, but not all volcanic eruptions are explosive. By studying the behavior of the volcano, volcano scientists can make predictions about future eruptions.
Step-by-step explanation:
The subject of this question is geography, specifically the study of volcanoes and volcanic eruptions. As a volcano scientist, you are investigating an eruption that has been going on for weeks and the lava is flowing slowly and far from the crater. The eruption is not very violent and very little ash is being ejected. People in the area want to know if there will be a massive eruption in the future.
Living near an active volcano can be risky, but not all volcanic eruptions are explosive. Some volcanoes, like those in Hawaii, erupt effusively, with lava flowing down the sides. It is important to study the behavior of the volcano, such as the type of eruption and the amount of ash being ejected, to determine if a massive eruption is likely in the future. By observing these characteristics, volcano scientists can make predictions about future eruptions.
