Since 2000, the world has seen more than 1,700 earthquakes measuring 5 or more on the Richter scale, mostly around the Pacific Ring of Fire. In North America, the greatest threat is the San Andreas Fault, which could produce a massive earthquake dubbed “The Big One.
” Scientists predict a 70% chance of a magnitude 6.7 earthquake occurring by 2030. While it is possible to prepare for a disaster, it is impossible to predict exactly when it will strike.
Previous major earthquakes, such as those in San Francisco and Fort Tone, have demonstrated the devastating effects. Older buildings that are not earthquake-resistant often collapse. In addition, power lines, gas lines, and mountainous areas prone to landslides are also potential hazards.
Damage to infrastructure, food, and clean water can cause serious disruption to life. The cost of recovering from a major earthquake is estimated to be as high as $200 billion.
But the San Andreas isn’t the only threat. The Cascadia Fault, which stretches from California to Vancouver, Canada, has the potential to produce a magnitude 9 earthquake, accompanied by tsunamis as high as 100 feet.
The area is a “sleeping beast,” with the power to destroy entire coastlines. The last time the area released energy was in 1700, and now it can repeat itself every 300 to 600 years.
Fortunately, countermeasures are being put in place. New building codes require buildings to withstand strong shocks. Early warning systems are also being improved to minimize damage. Still, if you live near the epicenter, the risk of damage is high.
In the event of an earthquake, it’s important to know how to protect yourself. After an earthquake, if there is a risk of a tsunami, move quickly to higher ground and take only essential items.
Do not return to the danger zone until you have received confirmation from experts that it is safe to do so.
In general, although these disasters are inevitable, being prepared and aware can help lessen their impact. Stay informed and listen to advice from scientists to ensure the safety of yourself and your family.
