I did this report for my third grade Science Fair in March 1998. I made a volcano model which really erupted by using baking soda and vinegar. When the baking soda and vinegar combine, they create a gas similar to the gas which causes volcanoes to erupt. I have included the recipe I used for the erupting volcano model.

Geology is the study of the earth. Volcanology is a branch of geology that studies volcanoes. Scientists who study volcanoes are called Volcanologists.

Volcanology is a new science that started in the early 20th century. Volcano observatories were built in Japan and Hawaii. These observatories monitor the world's volcanoes. They study active volcanoes during eruptions. They look for dormant volcanoes ready to erupt by watching for changes like new cracks in the ground, steam coming from vents or plants dying. Sometimes they measure the shape of the volcano, the ground temperature, and the level of gases. Seismometers pick up waves and analyze earthquake activity near the center of a dormant volcano.

Because of volcanologists being able to predict volcanoes, people usually have time to evacuate before the eruption. The land and homes might be destroyed, but the people will be safe.
