A powerful 7.2R magnitude earthquake has struck off Indonesia’s island of Sumatra, the United States Geological Survey (USGS) said today.

The Indonesian geophysics agency issued a tsunami warning after the quake, which the USGS said had hit at a depth of 37 miles, about 141 miles from Teluk Betung city. There were no immediate reports of damage or casualties.
The earthquake was a magnitude 6.8, and has triggered alerts and calls for evacuation. Indonesia’s disaster mitigation agency said residents on the Banten coast of Java island should “immediately evacuate to higher ground”.
