Elephants Warn Tourists of Tsunami

Description:  According to eyewitnesses a group of elephants heard the infrasound of an approaching tsunami and moved to safety. There are numerous accounts of animals sensing natural hazards, through sound waves or vibrations. This phenomenon could be used to investigate natural hazards and students could use these stories to build an early-warning system to protect humans from similar threats.

i have an idea about tsunami early detection, like through out our sea coastline from Gujarat, Maharashtra, Goa, Karnataka, Kerala, Tamilnadu, Andhra Pradesh, Orissa, West Bengal---- states about 6000kms sea coastline,( and also Pakistan, Srilanka, Bangalesh coastline)what is my ideas is that to maintain an animal herd centre, for every 100kms throughout the stretch of the sea coastline of our country Each Animal Herd Centre to contains: a) 6 Elephants (1/2dozen atleast) Elephants are most sensitive to ultra sonic sound, created by the tsunami wave, earthquakes, and behaves very strangely(erratically), when before earthquakes or Tsunami wave about to hit.

Yellowstone Supervolcano

Description:  Beneath Yellowstone National Park sits a large magma chamber that has erupted three times over the last two million years. Each of these eruptions was classified as an 8 on the Volcanic Explosivity Index (or VEI) making them supervolcanoes. A supervolcano forms when magma below the earth is unable to break through the surface crust and builds up pressure. Thankfully scientists are monitoring this volcano to protect humans from any future eruptions. This could be used as a phenomenon on natural hazards and the technologies that help to mitigate their effects.

One of the world's largest supervolcanoes erupted 2.1 million years ago in Yellowstone, and then twice more there at intervals of roughly 660,000 years. Are we due for another one soon? From: YELLOWSTONE SUPERVOLCANO http://bit.ly/1GmIMF3

Stilt Houses

Description: Stilt houses are built on pilings to avoid local weather conditions like storms and flooding. This engineering design solution allows humans to reduce the impact of weather-related hazards. Students can evaluate the merits of this solution or design solutions of their own for a local environment.
