Earthquake : The Seddon Earthquake

Over more than 50 decades there has been multiple earthquakes that have been caused by the activity that takes place beneath and above the surface of the earth. For every earthquake there are various effects and consequences, these are generally not preventable but teachable moments. As we study and explore landforms we learn and better understand how today 's structures came about, what took place decades ago and where do we go from here. Thanks to the technology and inquiring minds we are able to study past events like the 1906 San Francisco earthquake and the 1964 Alaska earthquake. In comparing these two events we can get an overview of what happened and better prepare ourselves for something like that in the future.

Imagine if you had to restart your life, new shelter, new job, new lifestyle. Well locals or people in the Philippines had to restart their life when an earthquake with an magnitude of 7.1 hit the country and destroyed people’s lives. The earthquake had a devastating 7.1 magnitude. The earthquake hit the Philippines on October 15th, 2013. The likely culprit of the earthquake was the East Bohol Fault because the two tectonic plates were sliding against each other and the creates an earthquake. Sadly, earthquake killed more than 90 people. Ports, schools, and airports were damaged. A hospital collapsed then that lead to a killing of 18 people. Children were also injured at sports complexes because people rushed the exits when the the ground started to shake. Lastly, 5 people were killed in a landslide that was triggered from the earthquake. What really matters though is how people respond to the

An earthquake is where two transform plate boundaries slide and creak the earth. This is what happened in the Philippines. Although it was in 2013 the people are still in need of help to get back to their daily lives. The Philippines earthquake had a magnitude of 7.1. This earthquake was gigantic, and it took down many buildings that were in its path. Lucky the children were not in school that day because of the Muslim holidays the earthquake caused the school to collaspe. If the children were in school, then it would have killed most of the kids.There were 2,100 aftershocks. The day of the quake was October 15, 2013. People respond to a natural disaster by gathering materials and donations, spreading the word, and the government's aid.

Have you ever been in a deadly earthquake? In 2013, the people of the Philippines experienced one. A 7.1 magnitude earthquake that affected around 43,000 people with 2,211 aftershocks that ended up killing a total of 185 people. Earthquakes are known as one of the most dangerous natural disasters. This horrific event happened October 15th, 2013. The earthquake hit hardest in the central Philippines, it was reported to be caused by the East Bohol Fault. People act in a response to a natural disaster by gathering resources, spreading word, and government aid.

The intensity of the earthquake was a major factor because its magnitude played a huge role in the damage that the disaster caused. It was reported to have hit a magnitude of 9-0 with the epicenter being located at least 80 miles away. The focus was 18.6 miles lower than the western Pacific. The result was a rapture of the subduction zone and thus led to the Japan Trench being affected. Several foreshocks reached as much as 6.0 and greater effects that ended up acting on the land in the following days and months even after the quake had subsided. The tsunami that accompanied the earthquake originated from a fault along the convergent plate boundary at the section where the Pacific plate joins with the west beneath Japan. The subduction zone was very active seismically at the time of the occurrence of the earthquake. Thus based on my understanding of earthquakes, the March 11 disaster was among the strongest earthquakes ever recorded because of the effects that followed because a portion of the ocean trench immediately went off-shore. In fact, it was later reported that a satellite that was orbiting around the Earth, infrasonics could be detected on the outer edge of the Earth’s atmosphere. The low-frequency waves meant that there were adverse effects that could be felt weeks after the real disaster had hit, hence the reporting that it was the

An earthquake also causes the ground to shake. Which some buildings can’t take the intensity

On April 18, 1906, in San Francisco, California there was an earthquake that was a major geological disaster that affected people in many ways. According to www.History.com, San Francisco had a population of around 400,000, and 3,000 people. The earthquake destroyed over 28,000 buildings and around 250,000 people became homeless. The damage costs were $500 in 1906. The magnitude of the earthquake was estimated to be a 7.8, but only lasted for 1 minute. The earthquake started many fires that burned for days and destroyed around 500 city blocks. The earthquake could be felt from Los Angeles to southern Oregon, and in central Nevada. This earthquake was caused by the transform plate boundary from the pacific and North American plates. The 2 plates rubbed against each other creating the earthquake. (decodedscience.org).

On March 11, 2011, Japan was devastated by a 9.0 earthquake that also created a 30 foot tsunami wave. This earthquake killed 15,000 people and injured more than 6,000. It is said that every 250 years on the Cascadia fault, an earthquake larger than the one that hit Japan, erupts. Scientists have determined that the Cascadia fault hasn’t erupted in 300 years. This means that the West coast is 50 years overdue for an earthquake that is powerful enough to destroy every bit of civilization. The probability of the Cascadia earthquake erupting in our generation is extremely high because an earthquake on the Cascadia fault happens every 250 years; plus the fault is hanging by a thread and could slip at any minute.

On October 17, 1989, two tectonic plates--the North American and the Pacific--slid against each other on the San Andreas Fault. The result was California having a 6.9 magnitude earthquake in the San Francisco Bay Area, also known as the Loma Prieta earthquake. The destruction was costly, with damages adding up to about $6 billion, but more so were the lives lost. The casualty rate of this earthquake was 63 people and over 3,800 injured. The count could have been a lot worse, however, had it not been for the baseball game at San Francisco's Candlestick Park between the San Francisco Giants and Oakland Athletics going on at the time of the natural disaster. Now referred to as the "Earthquake Series," the third game of the 1989 World Series collided

The earthquake lasted a total of 45 seconds, but 26 aftershocks occurred over an extended amount of time afterwards. When the earthquake hit, most people, other than some police officers, were asleep. The earthquake had a magnitude of 7.9 on the richter scale, so the not so earthquake proof buildings, fell on people as they woke up. 400,000 people in San Francisco underwent this terrible shaking. There were reports of people feeling the shake from southern Oregon to Los Angeles and inland to Central Nevada. Although, there were rich people that had their houses in places such as Nob Hill. Nob Hill was made completely upon bedrock, making the earthquake quite small and unproblematic. The reason the city had the earthquake so bad, was because the city wasn’t built on bedrock, but built on some dirt and such. During San Francisco’s gold rush, they decided to expand the city, by literally creating their own land, by packing a combination of trash, dirt and sand, and then building over it. They were not anticipating what an earthquake could do to that particular land. That land, also called South of Market, was hit so badly, some buildings sunk in the loose sand, dirt and trash, up to three stories. During the fires, the water mains in the city broke due to the earthquake's intensity. The water was leaked into the soil, creating mud. One building that was over the broken water mains, sunk into the wet mud 3 stories, and the last

The earthquake had Seismic Waves because the ground precisely outbreak open. It was also a Primary Wave because the earthquake was traveling 100 miles per hour. (Casey Farrell, UWEC), (Extreme Science) The damage that was destructed by the Chile quake was major. The quake caused around 500 Million Dollars worth of destruction.

Helens exploded but what is an earthquake? Earthquakes are the earth-shaking vigorously because the earth crust is moving which is caused by the tectonic plates. The lithosphere is made up of the earth crust and the uppermost mantle which is broken into the tectonic plate, that slowly move over a mechanically weaker layer, the asthenosphere, which is part of the upper mantle. These plates have different boundaries in the world, where two different plates meet, all of the boundaries are shown in this map. These plates are pushed together from interior earth, the plate's often collided near the boundaries causing volcanic eruption, earthquakes and tsunamis. There are different types of collision that cause different effects on our earth. Convergent boundaries- when two plates slide up against each other and one may be subducting under another . Divergent boundaries- are two plates pulling away from each other, which can create new

The San Francisco Earthquake of 1906, was one of the largest quakes ever recorded. It happened on April 18th, at 5:15AM. “The quake lasted only a minute, but caused the worst natural disaster in the nation’s history.”( Eyewitness History.) The quake caused an enormous amount of damage that affected hundreds of thousands of people’s lives.

Earthquakes are one of the most destructive natural disasters. They destroy buildings, collapse roads and bridges, change landforms, and have cause millions of deaths throughout the years.

It’s recognized as the second deadliest earthquake in New Zealand following the 7.8 Hawkes bay Earthquake (Kaiser et al, 2012). The earthquake was first thought to be an aftershock of the 7.1 Darfield earthquake of September 2010 at the eastern edge. This was an area that originally was of a low earthquake occurrence rate since prior to 2011 there was no knowledge of a fault’s existence thus catching the New Zealand citizens off-guard. The Christchurch earthquake resulted in 185 casualties affecting more than 300,000 people (Kaiser et al, 2012). The earthquake first made contact with in the South Islands, only 10 km away from the center of Christchurch. Ground motions were unusually large near Christchurch measuring 2.2 g and 1.7g at the epicenter, the point directly above
