Excavators clear rocks after Typhoon Noul caused a landslide in southern Thailand on Friday (September 18).

Strong wind and heavy rain reached Ranong province in the south of the country as the storm slammed in central Vietnam.

Officials said the weather had loosened the rocks on the hillside and they plunged to the ground in the early hours of the morning. Nobody was injured in the disaster.

Weerawat Sirikulpipat from the Ranong provincial government said it had rained over the past two days as Typhoon Noul affected the region.

In Khon Kaen province, in the north of Thailand, there was flooding caused by the heavy rain from the typhoon, which reached Vietnam's central coast after strengthening as it crossed over the South China Sea.

The typhoon is expected to move west into Laos and northern Thailand, where more severe rain and flooding have been predicted over the weekend.

The National Centre for Hydro-meteorological Forecasting is Vietnam warned of winds of up to 160 kilometres per hour.
