what is a tusunami in the first place
The side to side swaying of the earth resonates up the building and continues to vibrate up and down the length of the building, resulting in it's destruction. This happens when a building is build too rigid and not elastic enough to withstand the intense vibrations.
The destruction of a tsunami could make a building fall down or flood the building. the percentage is 100.9% of damage.
it all depends on the material that they build there building. In this case a brick building can resist if it has a good foundation of ground if not it could collapse. My best guess is less than 7.o or 6.6.
When building structures in a tsunami-prone area, it is important to elevate buildings above potential flood levels, use flood-resistant materials, and ensure strong anchoring of the structure to the foundation. It is also advisable to have tsunami evacuation routes and safe gathering points in place, as well as educate the community about tsunami safety and preparedness measures.
After a tsunami, prevention steps typically involve implementing early warning systems to alert residents of potential tsunamis, improving coastal infrastructure to withstand future tsunamis, enhancing public education and awareness about tsunami safety, and developing evacuation plans to ensure swift and organized evacuations in case of another tsunami threat.
Friction provides the necessary force to keep the building materials in place and withstand external forces like wind and earthquakes. Without friction, the structure would not be stable and would be prone to collapse. Friction is crucial for ensuring the integrity and safety of the building.
Japan has implemented various tsunami countermeasures, such as early warning systems, seawalls, and evacuation plans. Additionally, strict building codes and land-use regulations have been put in place to minimize damage from tsunamis. Education and awareness campaigns have also helped prepare residents for such disasters.
Build them out of materials and to designs specified to withstand tornado force winds.
That depends on how well the building was constructed. One of poor construction might only be able to withstand up to about a magnitude 5. A well constructed reinforced building may withstand up to an 8.5.
build a big and tall wall around the city
No. A basement is the last place you want to be during a tsunami. A tsunami is a massive surge of water. In a basement you are likely to drown. If a tsunami is coming you want to get as high up as possible. The best option, if you are in the danger zone, is to evacuate to higher ground inland. If you cannot then get to the top floor of you building or a nearby building, even on the roof if possible.
