Massive Mega-Quake Could Destroy Pacific Northwest Massive Mega-Quakes happen at regular intervals in the Pacific Northwest. There have been mega-quakes in the beginning of time. In Japan, a mega-quake send a 600-foot wave of water. The article I have chosen is the one on how “massive Mega-Quake Could Destroy Pacific Northwest”. The author notes that massive quakes have a magnitude of up to 9.2. It could last four minutes, according to seismologists. It occurs and then a wall of water follows. However, it could take up to fifteen minutes later. Individuals need to be concerned about the risks associated with the massive mega quakes. However, it seems that the people in the potential inundation zone have very little knowledge on the risks involved with mega quakes. Individuals that would be given a chance to live in the Pacific Northwest say that they would think twice. There is the need to offer education and training for the residents of the Pacific Northwest on the need for emergency preparedness and the things that should be done in case of massive mega quakes. …show more content…
• The author states that before the mega-quake actually hits, there is a compression wave that is detected by animals. It has received a wide debate as to the relationship between animals and the compression waves. It is said that animals start to react very strange and then two minutes later, there is a boom of a massive mega quake. • The other statement is that the New Yorker reported FEMA calculations that indicate that the massive mega quakes happen at regular intervals in the Pacific Northwest roughly every 240 years. Based on this statement, it implies that there has not been frequent massive mega quakes. However, geologists and paleologists can ascertain that massive mega quakes in the Pacific Northwest are usually often. Therefore, the geologists and paleologists do not concur with the statement.

There was a massive earthquake in San Francisco during the year of 1906. The country of United States went through great loss because of this massacre. Nearly 250,000 people had become homeless as the result of this great earthquake. Winchester pointed out the question: How unprepared was America when this disaster hit? He compared the San Francisco earthquake to the Katrina hurricane in 2005.
Earthquakes are best described as a shaking or vibration of the ground caused by breaking of rock. Sometimes they are very strong and other times you would hardly notice them. This shaking occurs when stress that builds up in the crust is suddenly released as the crust breaks free and/or slides against the other pieces of crust. Earthquakes may also be thought of as the breaking of a popsicle stick by applying pressure to both ends at the same time. Should you try this experiment , you will feel the pressure build up as you apply more force until the stick snaps. When the stick snaps you will feel an instant of pain at your fingers as the stress reduces and energy waves move throughout the stick. When the earth's crust is placed under similar types of stress, binding as the stress builds, it will also snap and release the energy into the surrounding rocks, 'ooch'. Thinking about earthquakes will become more clear if you try another experiment.
An earthquake felt throughout the Midwest on June 18 was a shaky reminder that earthquakes can occur anywhere.
On February 4th 1975 in Haicheng China there was a magnitude 7.5 earthquake. Over a period of months there were changes in elevation in land, ground water and unusual animal behavior which are all precursors to an earthquake. Days before the 7.5 magnitude earthquake there were foreshocks that triggered an eviction warning that effectively saved over 150,000 lives or injuries. This is a pro as this forecast saved thousands of lives and had the people of this area (knowing this was a place of seismic activity) took precautions, like that of earthquake resistant buildings, evacuation points, preparing disaster supplies among other preparations the following may not have happened or would have been less of a disaster.
I think being prepared and educated will save many lives if and when we get the big one in the Cascadia region.

Ten million California residents who lived closely from the major fault lines could have been endangered in many extreme ways. (House, 56). A tragic thing was that after the earthquake a multitudes of fire followed right after. The situation led to the water mains being destroyed and the firefighter being left with no water to settle the growing fire which continued blazing. The bay water was planned on putting all of the dure out but it was to far in distance to be able to transport it (Earthquake of 1906, 2). The firefighters who were putting out the fire were either surrounded or being burned by the fire that was blazing in all directions (San Francisco Earthquake, 2). A resident who was present during the event mention that he/she saw men and women standing in a corner of a building praying, one person who became delirious by the horrific ways that were surrounding him while crying and screaming at the top of his lungs “the Lord sent it, the Lord”. Someone also mentioned that they experience themselves seeing Stones fall from the sky and crushing people to death. Reporters say there were 100 cannons going off (San Francisco Earthquake, 3). People who lived fifty miles away from the fire was able to “read the newspaper at

The article lists volcanoes that have erupted and when they did so. Throughout the article there are pictures of volcanoes and the corresponding text shows what is being done to monitor them. The focus of the piece is the danger to Seattle and Tacoma posed by Mt. Rainier. The sand is rainy. There is an illustration of the danger zones of Mt. Rainier when it goes off and the towns that would be destroyed by it.
Before examining the Northridge event, understanding the naturally occurring hazard that is an earthquake will help to better understand exactly what happened and why it was such an important geological event. With four distinct layers, two layers, the crust and upper portion of the mantle, compose the skin that is the surface layer of the Earth. The crust is not a single, continuous piece. It is actually several different pieces, or plates, that come together to form the puzzle that comprises the surface of the Earth. These plates are in constant motion rubbing against one another. These areas, known as fault lines, where the plates rub up against one another have spots where one plate ”gets stuck while the rest of the plate keeps moving. When the plate has moved far enough, the edges unstick and is how most of the earthquakes around the world occur” (Wald, 2012). The energy stored from the friction of the two plate...
Another major effect of the 1906 San Francisco Earthquake was the long “rupture of a fault that has been observed in the United States” (USGS, 2012). According to the article Historic Earthquakes the displacement of the San Andreas Fault could be seen from a distance of 300 kilometers from San Juan Bautista to Point Arena. Further, displacement was beyond north at Shelter Cove in Humbolt County and if the rupture would it have continue the long rupture would it have extended to 430 kilometers becoming the longest displacement (USGS,
Natural disasters affect the lives of people in torturous ways. It almost always costs the lives of innocent bystanders. Costs of the cleanup can be in the billions of dollars. It is disturbing to realize the damage and destruction that nature is capable of releasing on humans at any moment. Both the eruption of Mount St. Helens and The Great Mississippi River Flood are different in many ways, but the same in that they both affected people negatively.
On the morning of Wednesday, April 18, 1906 an earthquake struck the City of San Francisco at 5:12 according to seismograph records. It was remembered as especially violent and everyone in the vicinity woke up to white dust in the air from fallen debris. As remembered by a bystander of the event, “I was awakened by a very severe shock of earthquake. The shaking was so violent that it nearly threw me out of bed... As soon as it was over I got up and went to the window, and saw the street filled with a white dust.” (Stetson, 21.) The strong shaking lasted from 45 to 60 seconds which were felt as far north as southern Oregon and past Los Angeles in the south. The water supply became shut off by the earthquake and then when fires broke out all ove...
This is one of the most commonly asked questions around the world. Earthquakes are very common because the Earth’s tectonic plates are constantly moving, because they are constantly moving earthquakes are happening quite often across the globe. Statistics show that over 1 million occur each year worldwide (see source 9), but earthquakes don’t have to be felt for them to have occurred. Statistics prove that 1 100 000 earthquakes happen per year worldwide that can’t be felt by humans. Statistics show that about 11 670 earthquakes occur that can be felt in the area of occurrence and sometimes even further
The earthquake with magnitude 9.0 and tsunami hit many regions of Japan and destroyed everything on its ways. The effects could feel over the world. Tsunamis hit Pacific coastal lines in many countries. Numerous people died, missing, or homeless. People lived in shelter, without clean water, power, telecommunication, etc. Japan is still recovering from the damages with the help of foreign relief. Radioactive from the meltdown and the aftermath debris affects the global environment. Learning the mega-thrust earthquake will help us improves the warning system that could save people and avoid serious
