When we talk about the seismic danger, a Big Earthquake that affects the United States, the vast majority of people only associate that with the San Andreas Fault. However, there is an even greater danger that for hundreds of years has remained silent: the Cascadia Fault. Centuries of tension have accumulated in the coast from northern California, United States, to southern British Columbia, Canada. Cascadia locates between the Juan de Fuca plate and the Pacific plate and has the potential to generate an earthquake of magnitude 9.0 since years of tension have accumulated along the entire fault of more than 680 miles in length. As that is not likely to predict when the next earthquake will strike, and seismic alerts consequently have an impact on it. Additionally, earthquakes are simulations to learn how to survive. The Big Earthquake predictions sometimes go beyond seismological research and become city legends or subsequently rumors. To avoid such confusions, the following statements are well-grounded to serve public opinion.


Cascadia Earthquake:

 After the earthquake – In the history of earthquakes tsunami happened if the magnitude was either near the ocean or in the sea. So, tsunami disaster has the potential to occur if there is a water element around the magnitude. In the case of the United States, such consequences are expected after immediate shock. Even though improved technologies allow us to take measurements and inactivate tsunami to some extent, but also there is no specific tool to eliminate occurring tsunami. On the other hand, such aftershock effects could be diminished through smart urban planning. That might sound weird.

However, the determinant of tsunami toll depends on human capital. The following determinants show how cities could get less damage from earthquakes if inhabitants, namely, urban planners contribute to the cause. Coastlines are very crucial in terms of hindering tsunami. If related parties are in the interest of safety, they should envision coastline settlement.

The more people live in here; the more death toll is subject to rising. Looking back in history, precise explanation of the earthquakes shows the degree to which people get damaged due to dense settlement on coastlines. In doing so, people are in danger of death. Because natural disasters are unexpected and destroy everything all at once, so, it is better to stick to the scientific approach, act accordingly.


Cascadia Tsunami, a Big Earthquake:

FEMA (Federal Emergency Management Agency) has made calculations and estimated that a total rupture of the fault would cause an earthquake, and later a tsunami, that would affect a flood area in which more than 70,000 people live, severely harming cities like Seattle, Olympia, Portland, and Salem, as well as the city of Vancouver in Canada. Such synopsis makes people anxious, but as the time approaches there is an urgent need to clarify the volume of wreckage.

A Big Earthquake is something you should keep in mind on a daily basis because there is no doubt that it is going to happen suddenly. Likewise, research results agency show that the hypothetical damage rate could be very high. Of course, these are big earthquake predictions, but still, there is room to worry. Both public agencies and residents should work together to reduce adverse effects.


FEMA has also predicted that the earthquake would seriously damage necessary infrastructures such as bridges and roads, interrupting electricity and water supply in some areas for weeks or even months. Also, more than one million people would have to leave their homes. Such earthquake would be felt even in northern California (including the San Francisco Bay Area), but a seismic alert system could alert populations in advance, before the arrival of the destructive seismic waves.


Official warnings



Before being informed about the alert system, self-awareness comes first as an incentive to survive in case a person gets stuck in a destroyed area during earthquakes. For that reason, to follow general rules of natural disaster management is an essential part for both residents and rescue officials. Furthermore, residents might apply concerning entities to demand earthquake simulation so that they can feel ready and safe during natural disasters.


The population is exposed to buildings that have not been designed to withstand high-intensity earthquakes (generated by great magnitude earthquakes in the Richter scale). These buildings include hospitals, schools, police stations and fire brigades. Recently they have begun to reinforce many structures to make them seismic resistant, but it is a process that takes years, and an early warning system must complement that.

However, to replace all structures and build up again are a time-consuming process, which is unlikely to get completed before a Big Earthquake hits. Therefore, public entities are required to take measurements and consult with the public show that there will be a standard tool to work out. Otherwise, without proper communication, the Big Earthquake will damage more than it is expected.


General recommendations


The population living in this area of the United States will have to learn how to respond to emergencies since they haven’t experienced anything similar, but above all, the inhabitants will have to be aware that this is a real and latent danger that should not be underestimated. An excellent first step is to have an early warning system, such as apps for the mass sending of seismic alerts for personal use.

Moreover, people are better off when they know safe places around them. Otherwise, in emergencies, residents could panic and put their lives at risk. At the same time, the approach to the case should slightly change if people want to get ready for any urgent conditions. Readiness to take up burden is not dramatic, reversely, it would sharply decrease the volume of damage in terms of death and material damage.


It is essential to mention that an Earthquake Early Warning is not predicting a big earthquake, but an alert system and the warning time depend on the extent to which you are going to get affected from and where you settle. While relying on scientific instruments to predict natural disasters, it is also inevitable to find a solution in terms of urban planning.
