Brief introduction to the PPT content of earthquake prevention and disaster reduction knowledge:

1. Understanding earthquakes

The average number of earthquakes that occur around the world each year

1-2 times a year for level 8 and above

Level 7: 10-20 times per year

Level 6: 100-200 times per year

Level 5: 1,000-2,000 times per year

On average, about 5 million earthquakes occur around the world every year, of which more than 50,000 are felt by people.

largest earthquake tsunami

The tsunami caused by the earthquake in Japan's Ryukyu Islands on April 24, 1771 had a wave crest height of 84.7 meters and a speed of nearly 800 kilometers per hour. A coral reef weighing 850 tons was thrown 2 kilometers away. The tsunami triggered by an 8.7-magnitude earthquake off the coast of Sumatra on December 26, 2004 killed nearly 290,000 people along the Indian Ocean coast.

Deadliest earthquake in the world

The death toll caused by the 8.0-magnitude earthquake that occurred in Huaxian County, Shaanxi Province, China on January 23, 1556 was more certain than the previous one. Many victims died of illness and starvation, and hundreds of miles of mountain villages were depopulated. It is estimated that more than 830,000 people died.

2. Precursors of earthquakes

Animals have precursors to earthquakes, and any abnormalities should be reported.

Cattle, horses, mules and sheep are not allowed to enter the pen, and pigs are not allowed to eat. Dogs bite them indiscriminately.

Ducks don't go into the water and make noise on the shore, while chickens fly up the trees and crow loudly.

Snakes come out of their holes in the ice and snow, and mice move away in a daze.

The rabbit jumped and bumped with its ears raised, and the fish jumped in the water in panic.

The swarms of bees are noisy, and the doves are frightened and cannot return to their nests.

Comprehensive analysis to distinguish true from false, group testing and group defense are very important.

3. Earthquake Escape

keep a clear head

When an earthquake occurs, it is crucial to have a clear mind and a calm attitude.

Only by being calm can we calmly judge the size and distance of an earthquake. Recent earthquakes often start with an up-and-down bump, followed by a side-to-side sway. Teleshocks have less bumpy feeling, but mainly swing from side to side, and the sound is crisp and the vibration is small. Generally, there is no need to flee for small earthquakes and distant earthquakes.

You can't run away from a big earthquake, but you don't have to run away from a small earthquake.

Take shelter nearby, lie down and wait for a decision

When a destructive earthquake occurs suddenly, there is only a few to ten seconds left. Taking shelter nearby and quickly evacuating after the earthquake is a good way to avoid danger. The interval between shock waves is the best time to escape.
