Earthquakes & Volcanoes Quiz
Tectonic plates, eruptions, and the Ring of Fire — test your geology knowledge.
Tectonic plates, eruptions, and the Ring of Fire — test your geology knowledge.
The Earth experiences roughly 500,000 detectable earthquakes every year, with about 100,000 strong enough to be felt and around 100 capable of causing damage. This quiz covers everything from tectonic plate boundaries and seismic waves to volcanic eruptions, the Ring of Fire, and the supervolcano beneath Yellowstone.
Each round presents 10 randomized questions from a pool of 50, with four multiple-choice options and instant feedback after every answer. Your final score comes with a performance tier and shareable results.
You'll explore plate tectonics, fault types, earthquake measurement scales, and famous seismic events throughout history. Discover the differences between shield volcanoes and stratovolcanoes, learn how tsunamis form, and find out why 75% of the world's volcanoes sit along the Ring of Fire.
Earthquakes are caused by the sudden release of energy in the Earth's crust, usually when tectonic plates move past, collide with, or pull apart from each other. Stress builds up along fault lines until the rocks fracture or slip, sending seismic waves through the ground. Most earthquakes occur along plate boundaries, though some happen along faults within plates.
The most powerful earthquake ever recorded was the 1960 Valdivia earthquake in Chile, which measured 9.5 on the moment magnitude scale. It triggered tsunamis that crossed the Pacific Ocean and caused damage as far away as Hawaii and Japan. The earthquake and resulting tsunamis killed an estimated 1,000 to 6,000 people.
While Yellowstone sits atop a massive magma chamber and has had three major eruptions in the past 2.1 million years, scientists consider the probability of a catastrophic eruption in any given year extremely low — roughly 1 in 730,000. The USGS continuously monitors the area and currently sees no signs of an imminent eruption. A hydrothermal explosion or lava flow is far more likely than a full-scale supereruption.
