Local media reports said the quake, which struck as people in the region were preparing for morning prayers, caused panic in North Sumatras capital of Medan and other cities in the province. Electricity was cut in Medan.
People in some cities along the southeastern coast of Sumatra as well as Sinabang on Simeulue island and Gunung Sitoli on nearby Nias island poured into the streets and rushed to higher ground, reports said. —AP
