Magnitude 7.7 quake leaves 40 dead on Flores and triggers evacuations; a 6.9 shakes Sumatra hours later as Indonesia confronts El Nino risk.
A magnitude 7.7 earthquake struck off Indonesia's Flores island around 6 a.m. local time Saturday, killing at least 40 people and damaging scores of buildings, the US Geological Survey said. The quake triggered a tsunami warning that was later lifted.
Ende, near the epicenter, is about 500 miles east of Bali and roughly twice that distance from Jakarta. About 13 hours later, a 6.9 magnitude earthquake jolted Pematangsiantar in North Sumatra, about 830 miles northwest of Jakarta. No casualties or damage were initially reported from the Sumatra temblor.
At least 52 aftershocks followed the main temblor, with magnitudes from 3.6 to 6.2, the Indonesian Meteorology, Climatology and Geophysics Agency said. The agency issued a tsunami warning for nearby coastlines and urged some residents to evacuate, then lifted it after the threat passed. Emergency authorities evacuated roughly 2,000 residents and moved patients and equipment out of several hospitals. Seventy homes were damaged, from severe to light, and at least 50 injuries have been reported, said Fathur Rahman, head of the search and rescue office in Maumere.
Indonesia's 17,000 islands sit on the Pacific Ring of Fire, an arc of fault lines and volcanoes that causes frequent seismic upheavals. Saturday's quake was the latest in that sequence. The country is also battling a surge in forest fires. A developing El Niño threatens drier weather at the peak of its dry season. Floods and landslides on Sumatra late last year killed more than 1,000 people and displaced more than 1 million.
Flores is home to Labuan Bajo, the gateway to Komodo National Park, which draws tourists to see the Komodo dragon. Last year, the eruption of Mount Lewotobi Laki-Laki in eastern Flores sent an ash column more than 10 kilometers into the sky and stranded thousands of holidaymakers, including those in Bali.
Major quakes around the world since June have caused thousands of deaths and billions of dollars in destruction. A 7.1 magnitude tremor in Japan in late July killed at least 30 people and jolted an area that serves as a hub for the country's semiconductor industry. A 7.4 magnitude quake in western Colombia on Monday left over 280 people dead and more than 10,000 homes uninhabitable.
Saturday's tremor was one of the largest to hit Flores since 1992, when a magnitude 7.5 earthquake caused significant damage, Wijayanto, a director at the agency, said.
