Subduction Zones Essay

915 Words4 Pages

Subduction zones can create beautiful landscapes such as mountains; however, they are also dangerous regions. Subduction zones occur because one of the plates that collide with other, in convergent plate boundaries, is of higher density. Hence it sinks into the earth back to the mantle (lecture 3, slide 24-26). When such phenomenon occurs, natural hazards such as earthquakes or tsunamis would occur, making these regions dangerous. Nevertheless, it does not limit traveling. Buying an insurance policy B would be more useful for this trip as it provides a greater sense of security. With more security, I would also be able to get more out of the beach holiday as I do not have to worry much about safety.

When megathrusts occur, the water above would be displaced. This cause waves to be created on the surface of the water and they can propagate over long distances. The waves also travel faster and creates larger crest when they encounter shallow waters (lecture 8, slide 13). Therefore, the tsunami wave can reach great heights when it hit the shore. Being close to the shoreline at a subduction zone can be very dangerous if a megathrust occurs. A famous example would be the 2011 tsunami in Japan which resulted in a 9.0 magnitude earthquake. The tsunami waves rose to a height of 3 to 38 meters and hit on Honshu’s coastline causing many casualties and devastating damages to the vicinity (Sorkhabi, 2011). Knowing that the subduction zone can creates megathrust to cause tsunamis, people have adopted preventive measures to reduce death toll. Educating civilians about the warning signs before the arrival of a tsunami wave such as waves retreating rapidly from coastline and vibrations of the ground is important. With these indications, it gives more time for people to evacuate from the coast to higher ground (lecture 8, slide 43 & 52). Seawalls and floodgates have also been built to reduce the impact of the coming tsunami waves and to redirect the waves respectively. If a tsunami was to occur at the beach, knowing the warning signs would give me time to evacuate from

Major cities affected by a disturbance in this subduction zone would include Vancouver and Victoria, British Columbia; Seattle, Washington; and Portland, Oregon. The two tectonic plates involved in the subduction process at the convergent fault line are the Juan de Fuca plate and the North American plate. The Juan De Fuca plate being the denser oceanic plate is being subducted under the continental North American plate. Although the fault line is on the coast of the Northern American plate tectonic activity is also heavily present inland, evidence of this is the cascade volcanic arc formed by the tectonic movements at the fault

The Earthquake Early Warning (EEW) was introduced during a workshop in February as a potential emergency planning and response system. Now it is going to be introduced to the public in preparations for any upcoming earthquakes. Similar systems are used around the globe and been proven to be extremely effective.

There were too many bodies to move and so few people who were capable of moving them (due to injuries) that the bodies would just be piled up on roads and in city squares. As a result of the earthquake, a total of 10,000 children were left orphaned.
