Shanghai and parts of China’s east coast are on alert for storm damage, with Typhoon Co-May making landfall in the city on Wednesday afternoon.

Warning of heavy rain and flooding, city authorities said the storm hit Fengxian district at around 4.40pm and was moving inland.

China’s Tsunami Warning Centre at the Ministry of Natural Resources issued a yellow alert – the second-lowest in the four-tier system – in the morning, warning that waves ranging up to 1 metre (3.3 feet) could hit Shanghai’s coast.

But that warning was cancelled in the early afternoon.

The earthquake, which was initially recorded as a magnitude 8, is now among the 10 strongest earthquakes in recorded history.
