Another quake rocked Indonesia's Sumatra island early this morning and the nation's meteorology agency has issued a tsunami warning. The quake, between 6.6 and 6.9 magnitude, was the latest to hit the island since Wednesday's powerful 8.4 tremblor set off a series of aftershocks. The latest tsunami warning has heightened tension among coastal residents, huddling in tents outside their damaged home, the Guardian reports.
The US Geological Survey, however, remained skeptical about the tsunami threat from today's quake. But a seismologist at Australia's Central Queensland University warned against complacency about a tsunami warning. More than 40 tremors have hit Indonesia since Wednesday.
