Tsunami

Tsunami in Crescent City


 
(Copyright Audio by Matt C.)

In March 2011 an earthquake in Japan caused a Tsunami that hit the Californian harbours of Crescent City and Oregon. When the waves came they seemed small and not dangerous. People who were watching the waves were swept away and rescued later on. The Tsunami caused millions of dollars damage, destroyed loose boats and docks. Fortunately, the cities have a protection wall and the 20-foot high waves did not break them.
Crescent City is like a Tsunami-magnet. Already in 1964 there was a Tsunami that destroyed 300 shops, the harbour and tanks of oil were in flames. Together with cars, trees and boats many people were caught by the waves and died in the floods.
Because of that catastrophe the city is now prepared for coming Tsunamis.

That is how the harbour looked like before the waves came.

The video shows how the harbour was destroyed and how lucky people are to have a protection wall. Even if you expect higher waves to repair the damage it will cost a lot of money and energy.

 

Can you imagine the damage if there would not be a protection wall?

Hurricane

Hurricane Katrina


(Copyright Audio by Matt C.)

On August 29, 2005 Hurricane Katrina hit the Gulf Coast of the United States. At that time Katrina was on a category 3 level, later even on a level 5 on the Saffir-Simpson Hurricane Scale. It brought 100-140 hour per miles winds with it. The storm itself brought a lot of damage but there was a catastrophe after it as well because it brought flooding. Thousands of people in Louisiana, Mississippi and Alabama had to leave their homes. Others had to climb on the rooftops to escape the water. A $100 billion damage was caused.

Especially New Orleans was hit very hard. 34,000 people had to be rescued. To help people offered food, boats and a place to rest.

Hurricane Katrina killed nearly 2000 people and left a destroyed place.

As one of the deadliest storms Hurricane Katrina was one of the five most destructive Hurricanes in the United States.

Who wants to know how a hurricane builds itself?
Then have a look at the animated guide.

As you can imagine such a hurricane causes a lot of damage. 
The video will show you how much damage it really caused. 


Have a look at the pictures. You can show and describe them to your classmates. What damage was caused?

Cold Wave

The Cold Wave 

(Copyright Audio by Matt C.) 

From December 2013 till January 2014 the Eastern part of the U.S was hit by an extreme cold wave. The freezing temperatures were brought by strong winds from North Canada. The temperature in Detroit for example was -14° Fahrenheit. Even worse, Canada had -30 to -40°.
The cold wave had two episodes. First record-breaking cold air hit the East of the U.S. Then, in January, a cold front brought heavy snowfall. Schools, roads and business had to be closed, flights were cancelled.
Because of the cold 21 people were killed.
That was the strongest cold wave since 1994.



Youtube is a good platform for your research. Have a look at the videos to see what happened.
