Along with clouds of ash and other volcanic debris that can linger in the air for years after an eruption, pyroclastic flows, landslides, and mudflows are common volcanic hazards. An explosive volcano may not be a hazard to human life and property, however, if it is located in a remote area or erupts infrequently. A number of factors must be taken into account to determine if a particular volcano poses a risk. Problem Which volcanoes on our planet pose the greatest risk to human life and property? Hypothesis Form a hypothesis about where you think the most hazardous volcanoes are located on Earth. Think about the potential risk to people and property near the volcano when formulating your hypothesis. Objectives Gather and communicate data about three volcanoes in different parts of the world. Form conclusions about the hazards posed by the volcanoes based on their location, size, lava type, and eruptive history. Data Sources Activity Links View Student Data Select a country and find out if there are any volcanoes in that country. If there are no volcanoes, choose another country. If there are a lot of volcanoes in that country, narrow your search. Repeat step 1 for at least two other volcanoes. Record the information about each of the volcanoes you selected in the data table below. Sharing Your Data Post your data in the table below. Use the additional data from other students to complete your chart and answer the Conclude and Apply questions. Which of the volcanoes you researched threatens the greatest number of people? Where is this volcano located? (Hint: Check an atlas or encyclopedia for estimates) Analyze the data posted by others. Which country has the greatest number of potentially dangerous volcanoes? Why? Which country has the greatest total population threatened by volcanoes?
