1. The area in Canada that is more likely to be affected by a major earthquake (megathrust) is the coast of British Columbia. In addition to the coast of British Columbia, the St. Lawrence, Ottawa River Valleys, and a few areas in the northern territories are likely to have earthquakes. The area British Columbia is in danger because the border is along the mark where the Pacific, the Juan de Fuca and the North America join. The earthquake occurs when the 3 plates rub against each other. The Juan de Fuca plate is shifting east under the North America plate, a few centimeters each year. According to John Claque, the motion is curling the edge of the North America plate upwards, much the same way a rug would buckle if you pushed on one edge. This creates a major strain on the fault line until eventually, the north America plate "elastically bounces back", causing the mega thrust and creating the tsunami". …show more content…
People may decide to live in earthquake prone areas due to environmental, economical, and social factors. One example of a social factor influencing someone's decision to settle in an earthquake prone area could be, that the family has lived in this area and are still living in the area (elders to take care of, siblings cousins). If there's land that people own, they probably depend on it to feed themselves and their family or they might enjoy the job they’re doing in the area. There are a few advantages of living in earthquake prone areas. For instance, along plate boundaries, geothermal energy is usually cheap and is also a clean source of power. Plenty of earthquake areas are near the coast, resulting in a good climate, as well as easy farming and
Activity of the Cascadia Fault is what had triggered the activity of St Helens in 1980 and in 2004. The Cascadia fault is a convergent plate boundary. The fault is a described as long and slopping, it starts in Northern Vancouver Island and expands down to Northern California. The Cascadia fault line separates the Juan de Fuca plate and the North American plate. Tectonic processes active in the Cascadia subduction zone region include accretion, subduction, deep earthquakes, and active volcanism of the Cascades.
On March 22, 2014 a 600 foot high hillside fell into the town of Oso, Washington. The total area consumed by the slide was 1,500 feet long, 4,400 feet wide and varied in depth from 30 to 70 feet deep – 49 homes and other buildings were destroyed, 13 people were seriously injured, and 44 people were killed (Department of Homeland Security 2015, p. 2). The slide itself moved “about 200 miles per hour, generating an estimated 10 million cubic yards of material covering approximately 318 acres” (Department of Homeland Security 2015, p. 2). According to eye-witness accounts it took mere seconds for the flood of debris to make its way down the hill. Other issues arose as a result of the mudslide, the river was dammed by the debris, which caused flooding
Between the North and pacific plates and the Queen Charlotte-Fairweather fault system Juneau has a high risk of serious earthquakes. Juneau frequently has multiple earthquakes a year. Last year Juneau went through over fourteen earthquakes and this year the city has only had six (Earthquake Track, 2015). Most of the earthquakes in Juneau are between two and four magnitude earthquakes. Juneau also has a history of serious earthquakes.
They also have a warm climate which gave a long growing season and fertile soil to produce crops such as fruits and vegetables. The southern region had the Tidewater which was a lowland with hot climate that produced
little movement from the tectonic caused big things such as earthquake, but what exactly is San Andreas Fault? San Andreas fault is major fracture of the Earth’s crust in extreme western north America (Brittanica). San Andreas fault have caused so many earthquakes in U.S.A, causing many destruction, and causing lost of lifes. Now, What made Northridge Earthquake so destructive? While the Northridge earthquake was happening Californian people couldn’t predict it (u-s-history.com).
Recently, on January 7th 2016, there was an earthquake caused by fracking, in Oklahoma, where earthquakes are rare. This particular quake was a 4.8 on the Richter Scale, which is the highest ever recorded. It occurred in the center of the state, was felt all over. Also, within the past week, there have been more than 20 quakes all over the state. in recent years, since 2011, earthquakes have occurred more and more often.
According to John Claque, the motion is curling the edge of the North America plate upwards, much the same way a rug would buckle if you pushed on one edge. This creates a major strain on the fault line until eventually, the north America plate "elastically bounces back", causing the mega thrust and creating the tsunami".
The Book I chose to explore was I Survived: The San Francisco Earthquake, 1906. Author and illustrated by Lauren Tarshis. I chose this book because I enjoyed the previous "I survived" novel that I read. This book is a Non-Fiction book because the events that occur in this book actually happened. Leo was an actual kid who experienced so much disaster that no one should have to go through.
It has fertile soil for growing crops. They have long growing seasons. They get lots of rain.
A tsunami is a series of great sea waves caused by an underwater earthquake, landslide or volcanic eruption. A tsunami is a series of many waves known as wave trains. A tsunami can also be generated by a giant meteor. Most tsunamis are known to be formed by underwater earthquakes.
They have the same impact like secondary hazard. They are tsunamis, secondary hazard, that causes after the earthquake, tsunami had killed a lot of people and destroy area around there. The effect for Valdivia earthquake are too big so they’re traveled across to the Pacific Ocean and traveled along to the southern Chile, Hawaii, Philippine, Japan and etc, with the speed are over than 200 miles per hour. While the effect for Alaska is also big, that why this incident which is caused tsunami and massive landslides are also affect a lot in Canada to Hawaii.
These two plates push and shove each other causing small tremors throughout which can cause landslides,volcanic eruptions and once in a couple years, quakes with devastating results. The strongest earthquake recorded occurred in 1991 with a measure of 7.6 on the Richter scale. This earthquake left 4 dead and buildings as well as bridges and road were completely destroyed. If another Earthquake occurs, the coastal cities would be the most affected ones as they are closer to the plates.
Why do people live in certain areas? There are many reasons people live in certain areas such as the availability of food, water, and jobs. The type of weather can also decide where someone will live. The ease of transportation in an area can also be a factor. People even live in an area because that is where their ancestors settled.
Earthquakes are caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two plates are rubbing against each other, they stick a little. Most earthquakes occur along the edge of the oceanic and continental plates. Due to stress they shift and cause the earthquake.
” Earthquake is like a place with a lot of surprises, disaster that should be prepared. “Earthquakes are considered as one of the most destructive natural disasters and can produce many types of losses, including
