- Crust - cool, lightweight, brittle, which floats on top of mantle. It is the outer layer of earth. Tectonic processes reshape continents and also cause earthquakes - Tectonic plates- plates caused by convection currents in the mantle that causes earthquakes. - Ocean basins form where continents crack and pull apart. - Magma – is molten rock
The asthenosphere is making convection currents. Since the convection currents are always moving it causes the asthenosphere to move and bend because it is ductile. When the asthenosphere moves which is under the tectonic plates it will cause an earthquake or more specifically the Alaskan Way
An earthquake strikes, demolishing a home as items plummet to the ground. However, that home is not in California, it is in the middle of Oklahoma. There is no fault line in that part of the country, so how did an earthquake cause so much damage? Was it fracking? Hydraulic fracturing, or more commonly, fracking, is the process of pumping water and chemicals into the ground to extract natural gas.
The more atoms that are in a certain amount of space the more dense it would be. This means the closer and more compact the atoms are in a space the more dense it is. The two layers of the Earth we focus on most for earthquakes is the asthenosphere and the lithosphere. The convection currents are in the asthenosphere and the tectonic plates and what the lithosphere is made up of they both are involved in earthquakes.
Juneau is in a very unique situation. The city faces multiple geologic processes that could be dangerous. These processes can be very hazardous. Some of the hazards the city faces avalanches, earthquakes, heavy snow, landslides, and tsunamis. Although the city faces regular avalanches and the possibility of landslides the town’s major hazard is earthquakes.
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).
The Great Chilean Earthquake which happened in the afternoon (15:11 local time) (SMS Tsunami Warning) of Sunday May 22nd 1960 was the largest of the 20th centrury, with a magnitude of 9.5, though it is disputed that it might have been 9.4 or 9.6. (Encyclopaedia Brittanica). The earthquake was so strong that in a chart of global seismic release from 1906 to 2005, nearly 25% of the world earthquake energy in a hundred years was from the 1960 Chile earthquake (Western States Seismic Policy Council). The earthquake was the cause of one of the “most destructive Pacific-wide tsunamis,” (Disaster Pages of Dr. George Pararas-Carayannis), and the tsunami caused by it affected southern Chile, Hawaii, Japan, the Philippines, eastern New Zealand, southeast
Effects of the 1906 San Francisco Earthquake Could you imagine if you lost everything you have ever worked for your whole life? After the 1906 San Francisco earthquake struck, many people lost everything they had. Over 3,000 people were left dead with a crashing economy, a city full of complete devastation, and years that it would take to try and rebuild the city. Even though the later effects of the earthquake brought people together, the immediate effects broke families apart. The reason is because so many people lost family members and friends.
How the Mishandling of the Great Earthquake of 1906 Began the Panic of 1907 Natural disasters and macroeconomics are not two topics one would normally think to place together as affecting one another; however, natural disasters have the ability to play a large role in macroeconomics. For example, as tectonic plates ruptured on a chilly, San Franciscan morning in 1906, the American economy soon followed suit in a rupture of its own. Although the San Francisco earthquake of 1906 was a natural disaster, it is believed that its poor handling set off a chain of events that caused the Panic of 1907. The destructive decisions made primarily by San Francisco’s corrupt Mayor Eugene Schmitz and ruthless Army General Frederick Funston in the aftermath of
The 1906 Earthquake On Wednesday, April 18, 1906, at 5:12 a.m., a 7.8- magnitude earthquake awakened the city of San Francisco. The earthquake lasted for sixty-five terrifying seconds of violent shaking and ended with an unknown number of dead family members, neighbors, as well as hundreds of thousands of people trapped in a city surrounded by water. To make matters worse, a series of fires broke out throughout the city. For three days, persistent, raging fires challenged the possibility of a coherent emergency response. By the end of the week, almost 98 percent of San Francisco's city structures in the most populated 521 blocks lay in ruins.
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.
Although the San Francisco Earthquake of 1906 and the Great Chicago Fire of 1871 were both horrific events that created huge destruction on the United States, they took a big toll in people’s lives in many different ways and encouraged them to take charge and rebuild back their hometowns that they loved. The San Francisco Earthquake commenced at five thirteen o’clock in the morning, with the epicenter offshore of San Francisco. The city carried more than 400,000 people during this event (Earthquake of 1906, 1). Most of the citizens who were present during the earthquake were all in bed asleep, but the early morning risers were able to witness the start of everything (The Great 1906, 5).
