2 powerful earthquakes hit Indonesia in one day, killing at least 47

A 7.7-magnitude earthquake that struck eastern Indonesia on Saturday killed at least 47 people, a disaster management official said, revising an earlier toll. A second, 6.4-magnitude quake struck the country's western Sumatra island later, according to the U.S. Geological Survey.

Authorities said dozens more residents were injured and warned that the death toll would almost certainly rise.

Authorities issued a tsunami warning and urged coastal residents to move to higher ground, but later lifted the warning when Indonesia's Meteorology, Climatology and Geophysics Agency said monitoring showed no significant sea-level changes that would pose a threat to coastal communities.

The U.S Geological Survey said the quake hit Indonesia's Flores region at 5:58 a.m. local time. Its epicenter was 42 miles north-northwest of the city of Ende in East Nusa Tenggara province. The meteorological agency said the quake was followed by at least 235 aftershocks, with the largest recorded at magnitude 6.2.

The head of the National Disaster Management Agency, Suharyanto, said rescuers have recovered at least 47 bodies, mostly in Sikka, Manggarai and East Manggarai, and at least 50 people were taken to hospitals.

Suharyanto, who, like many Indonesians, uses a single name, said the quake flattened at least 157 houses and damaged nearly 200 more, forcing about 2,000 villagers to abandon their homes and move to temporary shelters.

East Nusa Tenggara Police Chief Rudi Darmoko said the earthquake caused severe damage and collapsed buildings. He said power outages in cities and villages have hampered the flow of information and complicated search and rescue efforts.

"We are continuing to collect reports of damage and casualties, but there are communication disruptions," Darmoko said. He said that landslides in Ende regency triggered by the earthquake, also cut off the Trans-Flores highway, a roughly 435-mile paved mountain road spanning Flores Island, from Labuan Bajo to Larantuka.

The powerful tremor also destroyed more than 100 public facilities, including schools, medical centers and churches.

"I have never felt an earthquake this big," Yulian Juita Ekalia, who lives in Ruteng city more than 60 miles west of the epicentre, told AFP.

"It felt like we were on a trampoline; it was really scary," said the 37-year-old university lecturer. "As I rushed to get outside, everything in the house fell down: the television, my son's trophies, the dish racks, suitcases on top of the wardrobes. When I got outside, my son and neighbours were already there, screaming in fear."

The death toll could rise because landslides triggered by the earthquake buried or cut off many remote villages across six regencies on Flores Island, said Fathur Rahman, who heads the Search and Rescue Office in Maumere, the capital of Sikka.

Footage on local television showed patients at several hospitals being evacuated from buildings as a precaution following the quake. Hospital staff moved equipment outdoors, including beds, IV stands and oxygen cylinders, and set up temporary treatment areas to adapt to emergency conditions.

The National Disaster Management Agency deployed a helicopter to assist with logistics and support emergency response operations, including possible evacuations if needed, the agency said in a statement.

The air support is considered crucial given East Nusa Tenggara's geography, which consists of numerous islands and presents significant transportation and access challenges.

It said that about 2,000 villagers in Nagekeo regency fled their homes to temporary shelters.

Indonesia, a vast archipelago of more than 17,000 islands, is prone to earthquakes and volcanic activity because of its location on the "Ring of Fire," an arc of volcanoes and fault lines in the Pacific Basin.

Most notably, a powerful earthquake caused a tsunami in 1992 that killed about 2,500 people on Flores, part of a group of islands in the eastern half of Indonesia, while in 2018, a magnitude 7.5 quake spawned a large localized tsunami that wiped out coastal areas, killing more than 4,400 people.

In December 2004, a massive magnitude 9.1 earthquake off Sumatra in western Indonesia triggered a tsunami that killed 230,000 people in a dozen countries.
