This document discusses an inquiry workshop that uses authentic data to investigate volcanoes, earthquakes, and plate tectonics in Sumatra. The workshop focuses on Southeast Asia, examining geographical features, earthquake data, the tectonic setting which causes earthquakes, why volcanoes are present in the region, and why studying this is important for geography classrooms. Students will analyze real earthquake and geographic data to understand the relationship between tectonic plates, volcanoes, and seismic activity.
