The Sumatra Idonesia Tsunami, December 26, 2004
Now, let's talk about the tsunami in Sumatra, Idonesia that happened on December 26th, 2004. This tsunami is also the most recorded ever. The fault zone that caused the tsunami was roughly 1,300 kilometers long. The waves were as tall as 30 meters (100 feet). An estimated $10 billion damage is atributed to the disaster, and about 230,000 people died.
Last comes the Tohoku Earthquake and Tsunami that occurred on March 11th, 2011. The earthquake was at a depth of 24.4 kilometers and the tsunami waves hit the east coast of Japan. This was the largest earthquake to ever hit Japan in recorded history. It is also documented as the seventh largest earthquake in the world. The earthquake and tsunami led to about 15,000 dead or injured, about 2,800 people went missing, and 250,000 builldings were damaged and destroyed to rubble. It also caused a near nuclear disaster.

3.2 Top Five Worst Tornadoes
Number five of the worst tornadoes is the 1973 Manikganj, Singair and Nawabganj tornado. Bangladesh is one of the most tornado-affected countries in the world. In 1973 three areas were destroyed when a wide tornado hit their path and the whole large village of Balurchar was wiped out along with major parts of nine other towns. The death toll was 681.

Number two is the 1969 East Pakistan Tornado. An estimated 660 people were killed and 4,000 were injured. On that same day another tornado hit Homna Upazilla during which 223 people died. That adds up to a total number of 883 deaths.
Now comes the strongest one - the 1989 Daulatpur-Saturia Tornado, the deadliest tornado known to humankind. The draught caused the tornado due to the atmospheric conditions over the land. Thus, the already drought-affected areas were smacked by another natural disaster, a tornado. The estimated size of this tornado was 1 mile wide. In a matter of minutes, the horrific twister claimed the lives of 1,300 people. This tornado was furious like a lion in battle. It also left 12,000 people injured. The towns were completely destroyed, and 80,000 people were left homeless.

4.1 General Information
Tornadoes, check! Next topic – earthquakes! An earthquake is a powerful release of energy in the Earth's crust, that roughly shakes the earth. It feels like shaking and sometimes displacement of the ground. A powerful earthquake can cause tsunamis (as was mentioned in the section on tsunamis), landslides and sometimes even floods.
A seismograph records the magnitude of earthquakes on the Richter scale. If the magnitude is less than three, it is mostly imperceptible, but if it is seven, then there is serious damage. Now, that you have a description of the earthquakes, I will list some of the worst earthquakes in history.
