QUITO (REUTERS) - An earthquake in the Andean region shook Ecuador on Tuesday (April 18), witnesses said, sending people running into the streets in the capital of Quito a year after a deadly quake hit the country's Pacific coast.

The US Geological Survey said Tuesday's 6.0 magnitude quake hit about 260km north-west of the jungle town of Iquitos in neighbouring Peru. The town is not far from Ecuador's Amazon region, home to much of the Opec member's oil industry.

Petroecuador was seeking information about possible damage, a source at the company said.

The April 2016 quake had a magnitude of 7.8, killing around 600 people and destroying infrastructure along the coast.
