The Alaskan Earthquake Of 1964 Essay, Research PaperThe Alaska temblor of 1964 and following tsunami took 125 lives ( tsunami 110, temblor 15 ) , and caused about $ 311 million in belongings loss.

It is the biggest temblor of all time measured with an strength of 9.2 on the Richter Scale. Earthquake effects were large in many towns, including Anchorage, Chitina, Glennallen, Homer, Hope, Kasilof, Kenai, Kodiak, Moose Pass, Portage, Seldovia, Seward, Sterling, Valdez, Wasilla, and Whittier. To give an overview of where all these topographic points are in Alaska, here is a map taken from Microsoft Encarta: -Even though the map is non really elaborate, you can see which countries this great temblor hit.

An temblor is all to make with Plate Tectonics. As two monolithic home bases collide against each other, force per unit area builds up until one home base eventually gives manner. At this point monolithic force per unit area is released and seismal moving ridges travel through whatever they meet. If H2O is near to an temblor a Tsunami can happen.

These can be lay waste toing. The two home bases which caused the Anchorage temblor was the Pacific Plate ( Oceanic home base ) and the North American Plate ( Continental Plate. ) These two home bases have caused a subductive border in which the dilutant and denser pelagic home base honkytonks under the thicker and less heavy continental home base.

Over the old ages force per unit area would hold built up when the two home bases got stuck moving, and when one gave manner the Anchorage Earthquake began. Below is a diagram in which the Oceanic home base travels underneath the Continental home base, like with the North American Plate and the Pacific Plate.Anchorage was about 120 kilometres north-west of the epicentre and suffered the most terrible harm to belongings. About 30 blocks of houses and flats and concern edifices were damaged or destroyed in the metropolis centre. The J.C.

Penny Company edifice was damaged beyond fix and a new six-story construction collapsed, and many other multistorey edifices were damaged severely. The schools in Anchorage were about devastated. The Government Hill Grade School suffered a landslide and was about a entire loss. Anchorage High School was damaged badly.

The daze lasted for an estimated 3 proceedingss.Landslides in Anchorage caused a batch of harm excessively. Huge slides happened in the chief concern subdivision. The largest and most annihilating landslide occurred at a topographic point called Turn once more Heights.

An country of approximately 130 estates was devastated by supplantings that broke the land into many blocks that were collapsed and tilted at all angles. This slide destroyed about 75 private houses. Water brinies and gas, sewer, telephone, and electrical systems were amendss throughout the country.The temblor was accompanied by perpendicular supplanting over an country of about 520,00 square kilometres. The worst portion of the supplanting centered north-east from southern Kodiak Island to Price William Sound and carried on east-west. Vertical supplantings ranged from about 11.5 metres to 2.3 metres.

Off the southwest terminal of Montague Island, there was a perpendicular supplanting of about 13 & # 8211 ; 15 metres. Uplift besides happened along the southeast seashore of Kodiak Island. This zone of remission covered about 285,000 square kilometres, including the North and west parts of Prince William Sound and the west portion of the Chugach Mountains,This daze made a tsunami that devastated many towns along the Gulf of Alaska, and left serious harm along the West Coast of the United States ( 15 killed ) , and in Hawaii. The maximal moving ridge tallness recorded was 67 metres. .The temblor was felt over a big country of Alaska and in parts of western Yukon Territory and British Columbia, Canada.

Below is a map, which I retrieved from the United States Geological Survey Web site on the Internet. The map clearly shows where the epicentre of the temblor was, and which countries were hit the hardest.The Precise topographic point, clip and size for the temblor was Prince William Sound, Alaska 1964 03 28 03:36:14 UTC ( 03/27 ) , 9.2. Long Term Effects of the temblor were no where nigh every bit bad as the short term effects.

Since the cost of the temblor was in the order of $ 311 million for belongings loss entirely and with the loss of many concerns in the country, the economic system in the country suffered. Peoples in the country besides became stateless and many people lost friends and household due to the temblor or following events. This put people off traveling to Alaska and besides caused many people to travel off from the country.Changeless shudders are common in the country, such as this history from Deputy State Seismologist Charlotte Rowe, at the Alaska Earthquake Information Center, Geophysical Institute, University of Alaska Fairbanks.& # 8220 ; During July 1996, the Alaska Earthquake Information Center located 410 temblors in or near Alaska. The largest temblor during the month, holding a magnitude of 5.6, occurred on July 4 at 3:39 a.m.

This temblor was located in Cook Inlet, approximately 13 stat mis east-southeast of Skwentna, and 54 stat mis north-west of Anchorage. This temblor was felt in Anchorage, Palmer, Wasilla and Willow.Thirty-eight temblors of magnitude 4.0 and larger occurred during the month ; these are labeled on the attach toing map. Sixteen of these are aftershocks of the June 9, magnitude 7.9 temblor in the Andreanof Islands ( near Adak ) .Other temblors of involvement during July include:July 23 at 7:59p.

m. ADT, a minor temblor of magnitude 3.7 occurred six stat mis east-southeast of Eielson Air Force Base and 11 stat mis north of Salcha. This temblor was felt at Eielson, along Badger Road and in Salcha.July 27 at 3:17 ante meridiem ADT, a light temblor of magnitude 3.6 occurred 17 stat mis nor’-nor’-west of Anchorage. This temblor was felt in Anchorage and Eagle River.

& # 8221 ;Narratives like this brand you wonder why people live in temblor prone countries. Possibly it is because of the inexpensive land, good fertile dirt or merely the escapade of life on the border.9.2 on the Richter graduated table is an absolute monolithic temblor, in fact the largest of all time recorded. Merely to demo how big and intense the temblor was I have drawn out a table screening merely how large it is compared to other temblors.
