Shield VolcanoesSierra Grande in New Mexico

Made primarily of basaltic lavaMost produced by hot spots but also along subduction

zones and divergent boundariesMauna 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

• 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

Produced by subduction zones http://www.youtube.com/watch?v=1u1Ys4m5zY4&feature=related

Can produce: pyroclastic flows - can

reach up to 1000 degrees C and up to 700km/hr https://www.youtube.com/watch?v=vfIUYDjo8WM http://www.youtube.com/watch?v=c5CAyaRIW8s
