Earthquake in Vancouver

1. There hasn't been a major earthquake since 1700, known as the 1700 Cascadia earthquake, there could be another major earthquake soon especially with a bunch of more recent earthquakes in other subduction zones.

2. Our area is very close to sea level making it vulnerable to a tsunami and feeling major affects of a monstrous earthquake. There are tons of trees and loose rocks on mountain sides and lots of tall sky scrapers in the major cities.

3. a) Liquefaction would be a major issue in the South Delta, Richmond and Tsawassen area because they are at sea level and the ground can easily become liquefied.

Landslides would be a major area in the North Vancouver and Vancouver Island and Gulf Island areas because of all the forests and hill sides and mountains with loose rocks all over them.

A tsunami would be a major concern for Victoria and other cities along the coast of B.C. because they aren't a major land mass and can easily be swept under water and many peoples lives would be destroyed.

Flooding would occur along Vancouver Island and all the cities and towns along the Pacific Ocean like Vancouver and Richmond. The sea level would rise causing these areas at sea level to flood.

b) The social impact would be major as lots of lives would be in danger and the people who do survive would have a really long tough time of going back to a normal life.

Economic impact would be huge as many buildings would be damaged and destroyed and lots of roads and bridges and many other man made structures would get obliterated causing a huge price tag for our province and country.

Impact on our provinces infrastructures would be huge as it would take tons of time to repair and rebuild especially since the most expensive things are right at sea level. Also, it would take almost a whole generation to rebuild the affected areas to what they are today.

4. Metro Vancouver is preparing for this major earthquake by putting in earthquake proof pipes in downtown Vancouver and other sea level cities and some skyscrapers mainly in downtown Vancouver are getting earthquake proof structures causing them to be able to sway slightly without getting major damage.
