The initial quake struck at 12:49 pm (0949 GMT) at a depth of 6.92 kilometres under the sea, which lies to the south of the city, and lasted 13 seconds, he said.
''By 3:12 pm (1212 GMT), 51 aftershocks — the largest of which was 5.9 magnitude — had been recorded,'' he said.
As buildings shook, people rushed onto the streets where crowds of worried-looking people stared at their mobile phones for information or made calls, an AFP correspondent said.
