Before the Disaster
How A Tsunami is caused

Well that's all for today. I hope you enjoyed my presentation. Feel free to ask any questions now.
A Tsunami is an extended high sea wave that is caused by an earthquake, volcano eruption or land slides.
On Friday, March 11th 2011 at 2:23 p.m in Tohoku, Japan, police and fire fighters were sent out to warn the local residents that a tsunami was heading their way and the emergency responders advised them to get to high ground. News channels were broadcasting tsunami warnings to coastal residents and asked them to evacuate the area immediately. At 2:44pm, waves, three to thirty- eight meters high at 373km/hr, started heading to shore. Around 2:46 pm, water started to flood the streets, destroying everything in its path. The waves over topped and destroyed protective tsunami seawalls at several locations. The massive surge destroyed three-story buildings where people had gathered for safety. The powerful tsunami also generated a gigantic whirlpool offshore, captured on video.
Several hours later, waves stopped coming in and the attack by the tsunami was over, Tohoku, Japan, was ruined. Six months later, all of the water was drained and messes were cleaned. After a year, the Japanese National Police Agency reported that there were fifteen thousand eight-hundred and thirty-three deaths, six thousand one hundred and fifty were injured and two thousand six-hundred and forty-three people were missing. One hundred, twenty-nine thousand two-hundred and twenty-five buildings were completely destroyed. In addition, several roads and railways were also damaged.
The 2011 Japan Tsunami Disaster occurred from an earthquake. The earth's crust is made up of a bunch of pieces, called plates. The oceanic plates got moved around by the liquid layers of magma underneath the Earth's crust. The two plates ran into each other. When this happens the water gets pushed up creating high waves heading to shore, causing this tragedy, a Tsunami.
The 2011 Japan Tsunami Disaster affected the people, land and animals. Families lost their homes and vehicles. Everyone was left with nothing as the tsunami damaged everything. The land was ruined with the remains of homes, vehicles and even people. Trees and plants were all destroyed. About 250 animals were left dead or injured. Their homes were taken away with the tsunami and they were left with no food to eat. A couple of days after the tsunami, Japan declared an emergency for five nuclear reactors at two power plants after the units lost cooling ability.
In the future, Japan is coming up with more ways to lessen and minimize the destructive affects of tsunamis. Companies decided to make sturdier and stronger structures. The government of Japan decided to build a draining system beside the beach. In addition there will be high walls which are really strong surrounding the beach so high waves of water can't get through. Scientists and the people of Japan are still coming up with methods to make sure tsunamis don’t cause that much of destruction in the future.
-The 2011 Japan Tsunami Disaster was the most powerful known earthquake to ever have hit Japan
-The 2011 Japan Tsunami Disaster was the fifth most powerful earthquake in the world
-Many Nuclear Accidents were caused from the 2011 Japan Tsunami Disaster.
-A tsunami is not just one wave but a series of waves or a “wave train.”
-Not counting the 2011 tsunami in Japan, there were 26 tsunamis that killed at least 200 people or more in the last century.
-Once a tsunami reaches the shallow water near the coast, it slows down. The top of the wave moves faster than the bottom, causing the sea to rise dramatically, as much as 100 feet at times.
