Earthquake strikes off Indonesia's Sumatra, sending tremors as far as Singapore

A 6.5 magnitude earthquake off the coast off the Indonesian island of Sumatra early Thursday sent tremors as far as the neighboring country of Singapore.

The U.S. Geological Survey, which reported the earthquake at 6:56 p.m. ET, calculated that the quake occurred 56.5 miles west of Sungaipenuh on Sumatra, and 329.9 miles southwest of Singapore.

On December 26, 2004 a magnitude 9.3 earthquake off Sumatra set off tsunamis on the coasts of Indonesia, Sr Lanka, India, Thailand and 10 other countries, killing an estimated 230,000 people. The so-called Boxing Day tsunami was one of the deadliest natural disasters in recorded history.

Reuters reported on Thursday that there were no immediate reports of damage or injury in Indonesia, while BMKG Indonesia, the country's agency for meteorology, climatology and geophysics, said that there was no tsunami threat.

Early risers in Singapore took to social media on Thursday to say that they had felt tremors from latest quake.

Twitter's managing director for Southeast Asia also weighed in:

Although Singapore is not prone to earthquakes, the country has in the past felt tremors from large quakes in Indonesia. In early March this year, a magnitude 7.8 earthquake southwest of Singapore shook the city-state.
