what is earthquake?????
Answers
Answer:
earthquake is a natural cause
Answer:
Major earthquakes can cause widespread destruction when they occur near towns and cities. In 1848 an estimated 7.5 magnitude earthquake centred in Marlborough destroyed many of Wellington’s building’s which were mainly built of masonry and brick. In response Wellington was rebuilt with mostly timber buildings. Napier was devastated in 1931 by the 7.8 magnitude Hawkes Bay earthquake and the fires that followed. In February 2011, a 6.3 magnitude earthquake struck Canterbury, very close to the city of Christchurch. The earthquake's shallow epicentre was at a depth of only 5 km and lay just 6 km south-east of the city's centre. The proximity of the earthquake to the city caused extremely strong shaking, and other earthquake-related hazards, resulting in severe damage and the loss of 185 lives. New Zealand's latest major earthquake occured in Hurunui/Kaikoura on 14 November 2016 and was 7.8 in magnitude. It caused severe damage in the local area, and to buildings in the city of Wellington. It also caused parts of the South Island to move 5m closer to the North Island, and be uplifted by as much as 8m. The earthquake was so complex and unusual it has led to changes in the way scientists think about earthquake hazards in plate boundaries worldwide.
