VOLCANOS

FACTS ABOUT CINDER CONE VOLCANO

  • Cinder cone volcanoes are relatively small volcanoes that it's about less than 1,000 feet tall
  • At high foundation end of spectrum are cinder cones.
  • Cinder cones can be quite large in Hawaii, those on the summit of Mauna Kea (formed during gas-rich alkalic-stage eruptions) are a few hundreds meters high, whereas those were either the same or it has different shapes.

FACTS ABOUT PARACUTIN VOLCANO

  • The eruption of the paracutin scoria cone from 1943 to 1952 marks the first time scientists were able to observe the complete life cycle of a volcano, from birth to extinction.
  • Geologists the ones that study about many parts of geology of the world came here to study this extraordinary volcanic event.
  • The knowledge gained by these scientists greatly expanded our understanding of volcanism in general, and of scoria-cone formation in particular.

FACTS ABOUT SHIELD VOLCANO

  • Shield volcanoes are broad, low profile features with basal diameters that vary from a few kilometers to over 100 kilometers.
  • Their heights usually are typically about 1/20th of their widths.
  • This only gives shield volcanos a flank morphology that is convex in an upward direction depending where it takes place.
