Characterized by constant seismic and volcanic activity, the Pacific Ocean’s Ring of Fire is a vast horseshoe-shaped basin that sweeps over nearly 25,000 miles and includes more than 75% of the planet’s active and dormant volcanoes. Approximately 90% of the world’s earthquakes occur here, triggered by the volatile confluence of major tectonic plates in constant collision.

Join volcanologist and popular study tour leader Kirt Kempter for a geologic overview of the Ring of Fire and an exploration of how relentless tectonic movements drive earthquake and volcanic activity in hot spots such as Peru, New Zealand, Japan, and Alaska. Maps, diagrams, and Google Earth flyovers help convey geologic concepts and interpretations in the presentation.

NOTE: To explore this subject further, learn more about an upcoming evening series called A Geologic Tour of the Pacific Ring of Fire from April 12 to May 24, 2021.
