An earthquake has been felt in the tsunami-devastated Indonesian province of Aceh, causing panic but no reports of casualties. The quake measured 5.8 on the Richter scale and had its epicentre 90 kilometres south-west of the provincial capital, Banda Aceh. The quake was felt strongly at Calang in West Aceh but there were no reports of casualties or damage. Aceh was hardest hit by last year's Boxing Day earthquake that triggered tsunamis across the Indian Ocean, killing about 220,000 people.
