It would take roughly 24 million earthquakes of magnitude 2 to release the same energy as one earthquake of magnitude 7 (Day 15). This means, for all the energy stored in the fault to be released fully then 24 million magnitude 2 earthquakes must occur in order to prevent the magnitude 7 earthquake from occurring (Day 16). Since small earthquakes do not prevent bigger ones from happening, the feasibility of preventing the devastating earthquakes is based on dissipating the energy into smaller energies which will temporarily ease stress on the fault line (Day 16). Releasing the energy in small bits by use of the smaller earthquakes keeps the large and devastating earthquake from happening. This is due to the easing of the stress of the fault line which is vital for the magnitude of the earthquake that will be experienced (Day 16). The more the fault line eases, the less likely an earthquake of big magnitude will occur.
Mitigating earthquake hazards
The citizens of United States should follow the outlined actions to be taken when an earthquake occurs. Things like going under a strong furniture so that they are not hit by falling objects and also staying put without running in all directions (Smith 20). This will reduce the fatality rate that will be caused by the earthquake.
When building a house or putting up any structure, earthquakes hazards risk should be put in place (Smith 22). This means that the building should conform to all the safety standards that will make it safe during an occurrence of an earthquake.
The communities in Unites States should be provided with demonstration projects on earthquake mitigation as this will make them prepared for any eventuality of an earthquake. Agencies like the Federal Emergency Management Agency can provide awareness to the citizens on matters dealing with earthquakes and even give them necessary training that will be of assistance in dealing with the hazard caused by an earthquake (Smith 23).
Insurance companies should provide citizens on importance of taking earthquake covers. This will help the people affected with the effects of earthquakes to rebuild their lives after the hazards (Smith 24). This will reduce the extensive effect of the earthquake. Citizens should also place safety measures on existing buildings so as to reduce the hazard caused by earthquake.
The Federal government should be responsible earthquake warning system design, funding and operations because it is a natural disaster (Smith 34). By being a natural disaster, the citizens cannot be charged with the duty of financing or managing the early warning system (Smith 36). This warning system provides notification of a substantial earthquake while it is in progress (Smith 36). The Federal government should come up with a design of an effective warning system because it is a national disaster which affects everyone and it is the work of the Federal government to serve and make life of citizens comfortable (Smith 37). The Federal government should also fund the projects and run its operations for purposes of effectiveness. The early warning system should be the work of the Federal government because it is an expensive project that cannot be implemented by private citizens or NGOs.
Citizens should refurbish their houses to reduce the risk of destruction by an earthquake. Large portions of walls can be substituted with windows and glass doors in order to reduce the risk of an earthquake. Big structures should have bankers where the occupants of the structure can hide in when an earthquake strikes. This reduces the risk of fatality.
