Sumatra was rocked by an earthquake measuring 6.2 magnitude on Tuesday which was focused on the northern tip of the Indonesian island, the U.S. Geological Survey said.
Sumatra's earthquake, which was only 6 miles deep, struck 116 miles southeast of Banda Aceh, the capital of Aceh province, said the USGS, the Associated Press reported.

There was no tsunami warning and no reports of damage in the capital.
Indonesia is prone to seismic upheaval due to its location on the Pacific Ring of Fire, an arc of volcanoes and fault lines encircling the Pacific Ocean.
In 2004, a huge earthquake off Aceh triggered a tsunami that killed 230,000 people across Asia.
