2 How monitor?

3 Types of volcanoes http://www.youtube.com/wat ch?v=jRfEGvp6wDU&feature= related http://www.youtube.com/wat ch?v=jRfEGvp6wDU&feature= related

4 Cinder cone volcanoes Mt. Capulin, NM Most common type of volcanoes Smallest volcanoes Steep sides Made of piles of lava and scoria/cinders http://www.youtube.com/watch?v=aS_xl3nu_mYhttp://www.youtube.com/watch?v=aS_xl3nu_mY Paricutin, Mexico

5 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 http://www.youtube.com/watch?v=byJp5o49IF4

6 Hot spots http://volcanoes.usgs.gov/observa 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

7 Composite or stratovolcanoes MSH Produced by subduction zones http://www.youtube.com/watch?v=1u1Ys4m5 zY4&feature=related http://www.youtube.com/watch?v=1u1Ys4m5 zY4&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=c 5CAyaRIW8s https://www.youtube.com/watch?v= vfIUYDjo8WM http://www.youtube.com/watch?v=c 5CAyaRIW8s Slow lava flows http://www.youtube.com/watch?v= FnDT_6V4qVw&feature=fvw (MSH) http://www.youtube.com/watch?v= FnDT_6V4qVw&feature=fvw

8 Mount Saint Helens

9 Layers

10 Lava Canyon

11 Lava Tubes

12 Ancient Volcano features Santorini Caldera formed 3500 years ago formed by a huge volcanic eruption. Shiprock, NM – a volcanic neck that is the last remnant of the throat of a volcano from 27 MYA
