Natural History Museum features "Plate Tectonics Theater"


The National Museum of Natural History has a new exhibit on the second floor about the Solar System and the origin of planets, and offers a 15 minute film “Plate Tectonics Theater.” The film shows volcanoes and earthquake faults all over the world, separating the seventeen plates (eight major and nine smaller).

The film focuses on the supervolcano caldera under Yellowstone National Park in Wyoming and mentions that this caldera has given out three super eruptions in the past 1.5 million years, around the northwest. It hints that another eruption could occur at any time.

It doesn’t mention the mid-continent dimple at New Madrid, MO, discussed on Good Morning America this morning, site of the largest tremor in recorded US history, with six months of huge aftershocks, with a cycle every 500 years. Haiti is near a major plate boundary in the Caribbean.
