Question 1
Cascadia Subduction Zone is a one of the biggest and dangerous earthquake generated zone
widen up to 1000 km. It creates long dipped valley by creating the horizontal lines of the
earthquakes. It is the source of earthquake by creating conflicts within sediment plates. The
internal plates are widening from Northern Vancouver Island to Cape Mendocino.
Cascadia Subduction Zone is mainly located in northern America near California.
Plates named as Juan de Fuca and North America Plates would meet into the boundary of the
offshore for creating Earthquake. In this way newly generated Juan de Fuca Plate can help to
maintain the sub divisional boundary.
Question 2
Cascadia Subduction Zone suffers some dangerous earthquake because of its unstable plate
arrangement. It has seen that in 1906 San Francisco earthquake had created major impacts on the
place. However, the Geological examination states if the magnitude of the earthquake in the Bay
region is greater than 8 it can create a dangerous simulation by creating a devastating frequency
within the specific region by accumulating the power. Magnitude of the earthquake is
proportional to the length and stability (Afkar et al. 2013, p.69).
The large magnitude of the earthquake wave can deform the plate structure by destroying the
stability and increases the range of frequency. It is dangerous for nature by destroying the
environmental balance.
Question 3
As the plate of earthquake is located into the middle of the bay the earthquakes frequency is high
in the bay offshore. It would be most harmful to stay in between the sea offshore area (Al-
Rousan et al. 2014, p.510).
In 1906, San Francisco earthquake had occurred with the estimated magnitude of 7.8 by
maximizing the intensity and the frequency within the bay area. As the intensity of the
earthquake’s wave was extreme it was propagated within small time. Devastating condition of
fires within the whole region was occurred throughout the city. It needs a huge time to maintain
the entire process.
