7.8-magnitude quake rocks New Zealand
An extremely powerful 7.8-magnitude earthquake struck 50 kilometers (around 30 miles) northeast of the city of Christchurch just after midnight local time on Monday.
The earthquake triggered multiple aftershocks and at least three tsunami waves, with seawater levels rising about six feet.
The earthquake is the biggest since the 5.7 Valentine’s Day earthquake, which caused cliffs in the Christchurch suburb of Sumner to fall and liquefaction in some east Christchurch areas.
There were no immediate reports of damage or casualties.
