Wave that shook the world

Questions: 1. How do warning systems work? o Pick up seismic signals o Pacific Tsunami warning center Founded in 1949 after a tsunami struck Hawaii o Monitors the Pacific Ocean and if there was a magnitude of 6 earthquake, they would be notified o Sensors monitor determine how much water is above them and will send a message to the buoy which will send signals to a satellite which is then relayed to a warning station. o Tsunami Information Bulletin:  Let people know that there is a possible tsunami occurring from the epicenter.

2. What is the effect of coastlines on tsunami damage? o Vegetation, buildings, and the cities were completely destroyed o Looks like an aftermath of an atomic bomb o It depends on the morphology of the coastlines and the direction of the waves to determine how destructive is the tsunami  Ex. Surin Beach was nearly untouched  Kamala Beach was destroyed completely due to the shallow seabed allowing the waves to pile up  Tsunami train:  There are more than one waves of different heights and time periods in between them

3. How does the water get back into the ocean? o The water is drawn back out to the ocean at a similar force 4. What are the causes of tsunami? o Earthquakes o Volcanic Eruptions under water, or above the water

Tsunami Initiation released energy same as 23000 hiroshima bombs. Displaced water column splits which make the waves travel away from the uplifted area. In open ocean, Tsunami is very hard to be detected Tsunami grows in a process called amplification, The front of the wave slows down as it starts to reach land but the back of the waves catch up with the front causing a bigger wave Tsunamis are deadly because the volume of water is so great Tsunamis pick up debris while it continues to move which can kill a person and destroy buildings The earthquake they thought that was 8.5 was determined to be an 8.9 magnitude. The Warning Center had enough time to tell ease countries in Africa so they could evacuate the coastline All critical elements need for warning was missing for the Indian Ocean. If they had one similar for the Pacific Ocean, they could have saved a lot more times...
