Indonesia is ready to provide more coal to Japan to meet a surge in demand following the 9.0-magnitude earthquake last week, the Indonesia Coal Mining Association has announced.

Thousands of people have been left without hot water and power following the earthquake and the subsequent explosions at Fukushima Dai-Ichi nuclear power plant.

Indonesian Coal Mining Association vice-chairman Kaz Tanaka told Reuters that the country was ready to provide additional coal to Japan to meet the expected surge in coal use.

Though the additional demand for coal is likely to be limited to five to ten million tons over the rest of the year, it may increase if nuclear power plants damaged by the earthquake may not restart soon.

Indonesia ships over 70% of coal to the Asian market, with Japan being the top buyer.
