At last for conservations margins, the tension build up when plate are grinding past each other get stuck. Afterwards the plate will finally jerk past each other and sending out shock waves which is vibrations which is earthquakes. They both create lots of impact. For examples for the volcano eruption in Montserrat which is a LEDC, it cause 19
("Geology," 2008) It resulted in the folding of the area and shortened the north/south length of the area by about 8.7 miles. (Jaritz, 2008) “Kata Tjuta, near the end line of this bulldozing movement, was tilted only by15 degrees. But Uluru was rotated and almost tipped over at a steep angle close to 90 degrees.” (Jaritz, 2008) The near vertical sediment layers evident within the formation of Ayers Rock are due to this major earth movement. The continuing formation of Ayers Rock occurred slowly after the Alice Springs Orogeny. About 65 million year ago, the climate of the area had become extremely wet, and this brought river sand, swamp deposits, and small traces of coal to the area.
Due to high temperatures in the mantle of around 3000 degrees centigrade, this oceanic crusts melts and then rises due to the convection currents in the aesthenosphere . As it joins with trapped seawater and sediment, it melts the overlying continental crust, and the magma plumes rise to the surface. They contain more silica so are more viscous, which plugs up the volcano, meaning pressure build up. This is why these volcanoes are so explosive. Another type of plate boundary are constructive, which is the margin between two diverging plates where new magma
There is the main point of erosion which is corrasion, attrition, solution and hydraulic action. Corrasion is when waves carry debris (such as rocks, sand and pebbles). This is then hurled against the cliff face as the wave breaks on the cliff this will cause the cliff face to then crack and break off over a period of time. These fragments are then picked up by the wave and hurled against the cliff face; the process repeats itself with the new
More than 2,000 killed, 3,000 injured and $550 million damage in Chile; seismic sea wave caused 56 deaths, $75 million damage in Hawaii; 138 deaths and $50 million damage in Japan; $500 thousand damage to west coast of the United States. From ISC Bulletin, The International Seismological Summary. The following table lists particulars reported by the Survey for the larger shocks of the series of destructive earthquakes in central and southern Chile which began on May 21 and which is still continuing as of this writing in mid-August. The
They can cause widespread destruction, such as the 1980 eruption of Mt St Helens. Lahars are a secondary effect of a volcanic eruption and are cement-like mudflows consisting of volcanic ash and water. They often occur in the days following an eruption when people are at their most vulnerable and with the capacity to travel up
The magma that reached the sea bed due to weakness in the crust cooled quickly and formed a layer of basalt above the sediments (see diagram 1). Other magma intrusions
Overstrand’s cliffs are made from deposits of glacial till from the last ice age. The cliffs of Overstrand are made from soft rocks. This makes them prone to slumping caused by sub-aerial process for example weathering and saturation of the rocks. This leads to major slumping such as the slumping at Clifton Way were 40 metres was lost in 1990. Bacton’s geology is comprised of clay, silts and sand.
Hydraulic fracturing or more commonly known as “fracking” is an extreme water-intensive process. Fracking uses millions of gallons of water that is mixed with sand and harmful chemicals that is injected into the ground at a high pressure to fracture the surrounding rock. This process was started in the 1860s. It was mainly popular in places like Pennsylvania, New York, Wyoming, and Kentucky. They used liquid and solidified nitroglycerin but later applied the same methods with water and gas to achieve a greater outcome.
According to CBC News World, “The storm hit Haiti's rural western tip hard, flooding the refugee-camp homes of quake survivors.” (2010). The storm was actually downgraded from hurricane to tropical storm but still caused massive flooding with the vast amount of rain and mudslides that were rampant. The country also has a long history of earthquakes dating back to 1564. The most recent in this list is the 2010 earthquake close to Port-Au-Prince. The nation is located in a region seismic activity due to the movement of the Caribbean tectonic plate, which is compared with which a finger shoving away against two larger plates, the North American and South American.
