Notes and summary: animal behaviour and earthquakes

Short answer

A US Geological Survey study suggests unusual animal behaviour can help predict earthquakes. Animals seem to sense environmental changes hours or days before quakes, as seen in Tashkent, Agadir, San Francisco and Chile. In 1976 the Chinese predicted a major earthquake from such signs and evacuated millions, reducing deaths.

Read the following passage carefully, make notes and write a summary of it. A recent investigation by scientists at the U.S. Geological Survey shows that strange animal behaviour might help predict earthquakes. [passage of about 250 words on unusual animal behaviour before earthquakes in Tashkent, Agadir, San Francisco, Chile and China] ... In 1976, after monitoring bizarre animal behaviour, the Chinese predicted a devastating earthquake. Although hundreds of thousands of people were killed, the government was able to evacuate millions of other people and thus keep the death toll at a lower level.

Notes

Title: Animal behaviour and earthquake prediction

  1. Finding
    • US Geological Survey: strange animal behaviour may help predict earthquakes
    • Within 10 km of a recent quake's epicentre: birds screeched, dogs yelped and ran wildly
  2. Belief
    • Animals sense environmental changes hours or days before disaster
  3. Examples
    • Tashkent: restless for weeks; pets refused to go indoors an hour before
    • Agadir 1960: stray dogs left town
    • San Francisco safari zoo: llamas stopped eating and ran all night
    • Chile 1835 (Fitzroy): screaming seabirds; dogs fled; town destroyed
    • Records in India, Yugoslavia, Peru, Mexico, US (18th-19th centuries)
  4. China 1976
    • Quake predicted from animal behaviour; millions evacuated; deaths reduced

Summary

A US Geological Survey study suggests that unusual animal behaviour can help predict earthquakes. Scientists believe animals sense environmental changes hours or days before a quake. Birds, dogs, horses and zoo animals have behaved wildly before disasters in Tashkent, Agadir, San Francisco and Chile, and similar accounts come from many countries over centuries. In 1976 the Chinese used such signs to predict a major earthquake and evacuated millions, which kept the death toll lower.
