Answers: Earthquake and Lab Book Essay

Earthquakes have the potential to destroy and cause a lot of harm or they just make the ground shake a little. Sometimes earthquakes with low magnitudes cause a lot of harm, and a high magnitude one causes a small amount of damage. This usually isn’t the case. Two Earthquakes with high magnitudes each caused a different amount of damage. These two are the earthquake that happened in Sumatra, Indonesia in December 26, 2004, and the earthquake that happened in Rat Island , Alaska in April 2, 1965.

An Earthquake that registered 7.8 on the Richter Scale which lasted approximately 1 minute caused catastrophic damage to the City of Berkeley and LPHG. As a result of the Earthquake 31

These earthquakes were followed on Sunday, November 1, 1755, by a cataclysmic shock and tsunami that killed an estimated 70,000 people, leveling the city of Lisbon, Portugal, while many of its residents were in church. This event marks the beginning of the modern era of seismology, prompting numerous studies into the effects, locations, and timing of earthquakes.

Haiti, Japan, Taiwan...what do they all have in common? All 3 have had unexpected major earthquakes strike them and demolish there land. But what is an earthquake? An earthquake is the movement of earth’s tectonic plates. They happen because a mass energy causes the constantly moving tectonic plates to pass one another in either a transform, convergent or divergent movement, after a long period of time pushing against each other. They usually occur in cities located on the border of the tectonic plates like California, British Columbia (west coast) and Japan. Depending on the intensity of the earthquake, it has the potential to cause a lot of destruction and hurt many civilians. It can degrade community to a point where it would take years to recover. However much destruction has been caused, there are precautions that could be taken before hand to reduce the damage. This report will be comparing 3 major recent earthquakes from Haiti, Japan and Taiwan and how each country is doing post-earthquake.

It is not that strong compared to the S- wave, but it does wreck anything that is really stiff or not flexible enough to stand it, but do note that there is barely any building that can escape an earthquake not scattered except if it levitates. This can move anything that's hanging on the wall or knock down furniture. P-waves are much faster than S -waves and it is really weak compared to the other waves. It the shaking that you feel before the building collapse like when you press medium vibration on a massage chair. But mostly they are meant to weaken the structure of the base or crack the ground to prepare for the bigger

(May 22, 1960, Valdivia, Chile, Magnitude 9.2) The largest earthquake ever recorded was in Chile in 1960 and it was recorded at a magnitude 9.2. It’s said that 1,655 people were found dead and over 3,000 were injured. Two million citizens were left homeless after this natural disaster. ( March 27, 1964, Prince William sound,Alaska,Magnitude 9.2) The Gulf of Alaska was devastated by the Prince William Sound earthquake that of the 131 people killed during the earthquake, 119 died in the tsunami. Most were killed by the tsunamis triggered by underwater landslides, not by the earthquake-induced tsunami. (December 26, 2004, Northern Sumatra Indian) The giant earthquake of 2004 in Sumatra ruptured the longest fault length that has ever been recorded

This lack of management lead to the collapsing of 5m buildings along with a further 21m damaged. This included 8 schools which were toppled in Dujjangyan, killing and trapping school students. China did not create an adequate seismic design code until after the 1976 quake and even then it was difficult to enforce building regulations, producing a total estimated economic loss of $86b. Making this the second mostly costly earthquake from 1900-2013. The impacts of this earthquake were caused primarily on human factors, with adequate predicting systems and improved infrastructure the total loss and damage could have been reduced.

On the islands of Hawaii a 6.6 earthquake hit the island Honolulu. The lack of electricity gave them no communication with the mainland.

Oklahoma has been on the spotlight for the last few years owing to the increase in earthquakes. Particularly, 2014 served a wake-up call for stakeholders such as government, researchers and oil and gas industry members as a result of a sharp rise in earthquakes reported in the area. The year saw Oklahoma receiving more earthquakes than compared to California, a region that is more culpable to the earthquakes scene. In adition, 2014 also marked the largest earthquake reported in the history of the region, reporting a massive 5.6 magnitude. With these developments, continous research has been conducted and the review of peer and academic journals written by past reseaerchers and academic institutions collected to add on the data required to unearth the cause of the frequency of registered earthquakes as well as the underlying factors that contribute to seismic activity.

Earth is a life giving planet. It is also true that it’s never at rest. It is in a daily course of revolution and rotation, making us experience not only night and day, but also seasons. This planet goes through many changes that brings wonders, but also catastrophes. These forces of nature leave damages and deaths all over the world. One of these cataclysm is earthquakes. What exactly is an earthquake? An earthquake is the ground shaking caused by the sudden movement of one block or rock slipping past another along the faults (Lutgens, Tarbuck). There is a process that causes an earthquake to happen. First it involves the heating, followed by

the earthquake lasted over 4 minutes in some areas while in other it only lasted seconds. the nations who gathers their heads and put aside their difference and decided to help them saved hundreds of thousand lives but, that day about 316 thousands people were killed. by January 24 2010 at least 52 after shocks from the earthquake were reported. most of those after shocks were ranked at about a 4.5 and were strong enough to bring down many homes and buildings ( en.m.wikipedia.org, n/a, January 12 2010)

To lead off, earthquakes have caused severe damage to architecture. The vibration, caused by the collision of continental plates, often damages the infrastructure of buildings, causing them to come tumbling down. Repairs are often extremely costly. According to the Sandra T. Upton’s insurance claim, the total expenses added to $54,880 for just one home. In the news report of the Loma Prieta earthquake, it states that “...tens of thousands of buildings were damaged or destroyed, and the final repair bill came to $6 billion.” In addition to the cost,

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

In this report, I will be comparing and contrasting the February 2011 Earthquake in Christchurch and the July and August earthquakes that occurred in Seddon and Lake Grassmere, discussing why New Zealand has so many earthquakes
