7,500 earthquakes hit New Zealand city

However, only a few hours have passed since a new wave of aftershocks rocked the city of Christchurch last night.

Seismologists said they recorded 7,500 earthquakes in Christchurch since September last year, averaging more than 20 aftershocks a day . The tremors made the land under thousands of houses become unsafe.

Christchurch is a disaster that the world cannot forget. When the deadly earthquake collapsed this cathedral and flattened many buildings in the city of 390,000 people, people around the world gathered their attention here. However, two weeks later, earthquakes and tsunamis caused more than 200,000 deaths in Japan, causing interest to shift.

In New Zealand, what happened in Christchurch is still reverberating. In the country of 4 million people, earthquake losses - estimated at more than 12 billion USD, account for 8% of New Zealand's annual economic output.

No one knows, the worst thing has passed or not.

In Christchurch, the first 7-degree earthquake on September 4, 2010 did not cause widespread destruction because the epicenter was located 50km west of the city but it created at least two new earthquakes on broken roads. different. The first deadly earthquake hit Christchurch on February 22 with epicenter just below a residential area. This 6-degree earthquake flattened the building that stood still in the previous earthquake.

Then, on June 13, new earthquake, 6 degrees happened. Although no one was killed, it was a psychological blow for those trying to rebuild this city.
