JAKARTA, Indonesia (AP) — A strong undersea earthquake shook western Indonesia on Friday, but no tsunami warning was issued and no damage was immediately reported.
“People were running from their houses," said a local disaster mitigation agency official, Hiramo, who goes by a single name.
The U.S. Geological Survey said the magnitude 6.6 quake struck at a depth of 10 kilometers (6 miles) and was centered 257 kilometers (159 miles) south of Sinabang, a town on the east coast of Simeulue Island, which lies off the western coast of Sumatra.
No tsunami warning was issued by the Indonesian Meteorology, Climatology and Geophysics Agency, and no casualties were immediately reported.
Indonesia, a vast archipelago of 271 million people, is frequently struck by earthquakes, volcanic eruptions and tsunamis because of its location on the “Ring of Fire,” an arc of volcanoes and fault lines in the Pacific Basin.
Indonesia's latest major earthquake was in January, when a magnitude 6.2 earthquake killed at least 105 people and injured nearly 6,500, while displacing more than 92,000, in West Sulawesi province.
