Transcript of TSUNAMIS LISBON PORTUGAL 1755


On All saints day, Lisbon went through the three tremors over the course of 10 minutes that suddenly struck. The worst of the quakes was thought to have a magnitude 8.0 and was felt like it was shaking from far away from Morocco.
Effects
The devastating effects of the earthquake felt throughout the city. Close to the coast a huge tsunamis rushed ashore and killed thousands.At the time many people were hiding in churches and died when the building collapsed. Fires broke out all over the city and the wind spread it quickly. The royal palace was destroyed, as were thousands of homes.
The plate moves by magma or lava that comes out of the earth. Most of this happens at the bottom of the ocean. When the earth crust is thin, the lava cools down when it reaches the water, and underwater mountains are formed. Some plates slide past each other for example: one moves north and the other moves south . When these plates move along a lot of energy is released and the biggest earthquakes happen.
Scientific Explanation
Underwater earthquakes push water upward to create the movement, then gravity pulls water downward creating the horizontal force that forms the tsunamis. The waves travel through the ocean in a similar fashion to ripples created by throwing a stone into a body of water.

Issues
To be prepared for the tsunami you need to make sure you plan your evacuation route from home, school, workplace or any place for safety. Practice the route and make sure you have an radio to keep contact of all the warnings or safety hazards.
Some people build their houses in the wrong place because there might have been history about tsunami being there for some time. plus it is also no safe. It also depends the type of house you build if it is not the type for tsunami then the house will collapses.
Another issue is you need to be careful of explosion because in a tsunami because it probably won't end as well.
