Cinder cone volcanoes Mt. Capulin, NM Most common type of volcanoes Smallest volcanoes Steep sides Made of piles of lava and scoria/cinders Paricutin, Mexico

Shield Volcanoes Sierra Grande in New Mexico Made primarily of basaltic lava Most produced by hot spots but also along subduction zones and divergent boundaries Mauna Loa, the largest of the shield volcanoes, is 4km above sea level, which means it rises over 8.5km above the ocean floor. This is the Earth’s tallest mountain. Olympus Mons is the tallest shield volcano in the solar system: 624 km in diameter and a height of 25 km

Hot spots tories/yvo/ 3 supervolcanic events at YNP Ash as far away as Texas Last super erution - 640,000 years ago Last big eruption 70,000 years ago – basaltic lava flow: 15-92m thick and size of DC
