22 Yellowstone Caldera

24 Yellowstone – Over a hot spot in Earth’s mantle and could have a massive eruption

25 Crater Lake, Oregon

26 Increases in earthquake activity Pressure from magma on the overlying rock changes the rock temperature The surface of volcano may bulge upward Predicting Volcanic Eruptions
