I, Choose the item (A, B, C, or D) that best completes each of the following sentences. During the first 80 years of the existence of the European settlement in Christchurch (1850-1930), four major earthquakes caused significant damage. The last of these happened in 1922 near Motuno, in the north of Canterbury. Simulations carried out for New Zealand by the Earthquake Commission (EQC) in 1991 showed that earthquakes with a Mercalli intensity of VIII (significant property damage, life-threatening) and above can recur in Christchurch on average 55 years. The study also highlighted the danger of liquefaction of the alluvial sediments on which the city stands, as well as the high likelihood of damage to the water supply, sewerage, and electrical communications. About 100 tectonic faults and fissures have been discovered within a radius of 20 km from the center of Christchurch. The nearest faults, capable of causing powerful earthquakes, were found in the Rangiora - Kast region, near Hororata and Darfield. However, the 2010 earthquake struck a previously unknown fault. Seismologists have hypothesized that the main earthquake in 2010 could have been two or three nearly simultaneous earthquakes. The main quake occurred as a result of shear in the crust of the Pacific Plate near the eastern foothills of the Southern Alps on the western edge of the Canterbury Plain. The epicenter of the earthquake was located approximately 80–90 km southeast of the convergent boundary of the Australian and Pacific plates, passing along the island (Alpine and Hope Fault). Despite the distance from the boundary, the earthquake reflects right lateral movement in one of the many local faults formed as a result of the general relative movement of lithospheric plates and is associated with the spread of the Marlborough fault system to the south during recent geological time. ANSWER THE QUESTION: 1, The effects of the great earthquake in 1991 ________. A. damage to property and physical B. affecting human life interfere. C. property damage significant, life-threatening, may recur 55-year average. D. affect the individual rights of the people. 2, What theories do seismologists have about the upcoming earthquake? A. Make predictions about the earthquake in 2010. B. Hypothesized that major earthquakes in 2010 maybe two or three earthquakes occur almost simultaneously. C. It will occur due to a rupture in the crust of the Pacific Plate. D. Occurs at least 2 or 3 times in 2010. 3, How many earthquakes have occurred in Christchurch? …………………………………………………………………………………………………………… 4, Which of the following is NOT mentioned in the above paragraph? A. The earthquake can cause damage to the water supply system, sewerage, and electrical communications. B. Fissures in the Rangiora - Karst region can cause strong earthquakes. C. Earthquake motion to be reflected by one of the many local faultings. D. The cause of the earthquake was the destruction of nature. 5, Which sentence is NOT true according to the last paragraph? A. The main earthquake occurred due to the rupture of the crust of the Pacific plate. B. The epicenter was located about 80-90 km south-east of the confluence of the Australian and Pacific plates. C. Earthquake reflects the move right from one of the many local faults. D. The earthquake is not related to the Marlborough fault system.
