An earthquake of magnitude 6.6 struck off the northwest coast of Indonesia's Sumatra island on Friday, the GFZ German Research Center for Geosciences (GFZ) said.

The Indonesia earthquake was at a depth of 10 km (6.21 miles), GFZ said.

Indonesia's weather and geophysics agency, BMKG, put the quake at 7.2 magnitude and at a depth of km but said it had no potential to trigger a tsunami wave.

On Dec. 26, 2004, a 9.1 magnitude quake off the coast of northwest Sumatra triggered a tsunami that killed more than 230,000 people in Indonesia, Sri Lanka, India, Thailand and nine other countries.

A magnitude 6.0 earthquake has rattled northeastern Japan, but authorities have not issued a tsunami warning.

There were no immediate reports of casualties or damage to property on Friday and no abnormalities were found at the region's nuclear power facilities, including the crippled Fukushima Daiichi Nuclear Power Station, according to the Nuclear Regulation Authority.

The quake occurred at 8.58am (0958 AEST), its epicentre off the coast of Fukushima prefecture at a depth of 40 kilometres, the Meteorological Agency said.

In February, a magnitude-7.3 quake also struck the northeast, killing one person and injuring about 190 others.

Japan recently observed the 10th anniversary of the magnitude 9.0 quake and resulting tsunami in the same region on March 11, 2011, which left about 18,400 dead or missing.

The people of Chile and neighbouring countries are used to earthquakes, as the region is part the Ring of Fire - an area around much of the rim of the Pacific Ocean where many volcanic eruptions and earthquakes occur due to the collision of lithospheric plates.

According to the European-Mediterranean Seismological Centre (EMSC), the earthquake hit off of Coquimbo on Sunday morning. The quake's epicentre was located at a depth of around 10 km (6.2 miles).

So far, there have been no reports about any damages or casualties, caused by the tremor.

Magnitude 6.8 earthquake jolts northern Japan

quake
A 6.8 magnitude earthquake that also measured a strong 5 on the shindo (intensity) scale struck off Japan's northeastern coast on Saturday but no tsunami warning was issued, Japanese and U.S. authorities said, with no immediate reports of damage.

The United States Geological Survey (USGS) said the midmorning quake hit at a depth of 47 kilometers (29 miles) in the Pacific, off Ishinomaki, Miyagi prefecture, near the epicenter of the huge March 2011 quake that triggered a towering tsunami, killing more than 18,000 people.

The USGS and Meteorological Agency said there was no tsunami risk following the jolt, which produced strong shaking along parts of the eastern coast and was also felt in Tokyo.

A 6.0 magnitude earthquake has rocked the Indian state of Assam, with many witnesses reporting powerful tremors felt across the country's northeast amid a series of aftershocks.

The quake struck near the towns Dhekiajuli and Tezpur at a depth of around 18 miles (29km) on Wednesday morning, according to the US Geological Survey (USGS), while the European Mediterranean Seismological Centre (EMSC) recorded a depth of just shy of 25 miles (40km). Aftershocks have been reported, with USGS noting one at a magnitude of 4.9 and the European agency listing a total of four, ranging between 3.6 and 4.9 on the Richter scale.

Residents, including a local government minister, took to Twitter to report the "massive" quake, with one deeming it the "scariest earthquake [I have ever] witnessed." Another local said his "whole house vibrated" during the tremors, which he felt for more than 30 seconds.
