A mining accident in Indonesia’s West Sumatra province buried 12 miners on May 14, nine of whom were killed, following a period of heavy rain.The disaster is the latest fatal accident at an unpermitted mining site in the interior of Sumatra in recent years, with officials and civil society analysts saying the sustained high price of gold, which at the time of writing was threefold higher than six years ago, is drawing more people to illegal mines.Walhi, Indonesia’s largest environmental NGO, said at least 48 people were killed in West Sumatra, one of Indonesia’s 38 provinces, in the last 15 years.The green group said the true number could be much higher owing to the remote nature of the illegal industry.

PADANG, Indonesia — Nine people were killed on May 14 in Indonesia’s West Sumatra province after heavy rain triggered the collapse of a 30-meter (100-foot) cliff at an illegal gold mine.

“Three people survived, while nine others who were buried have been recovered deceased,” said Susmelawati Rosya, a spokesperson for the West Sumatra province police.

Local officials said miners had ignored repeated warnings to stop work amid sustained torrential rain, and that the high international price of gold continued to draw people into the risky work.
