A powerful magnitude 7.7 earthquake struck off the coast of the Indonesian island of Flores Saturday morning, killing at least 47 people, damaging buildings and forcing residents to flee their homes.

The earthquake struck about 6 a.m. local time, about 68 kilometers (42 miles) northwest of Ende in East Nusa Tenggara province, according to the US Geological Survey (USGS).

The latest toll was given by disaster mitigation agency BNPB in an update Saturday evening local time. In addition, 50 people have been injured or severely injured, BNPB said. About 2,000 residents have been evacuated.

A tsunami warning was initially issued but later lifted, it said. Some waves up to 1 meter (3 feet) high were recorded in Maurole, Ende, according to Indonesia’s meteorology, climatology and geophysical agency.

The quake was felt across Flores, a lush and mountainous island in the Sunda chain, which also includes tourist hotspot Bali. Flores is known for its colorful volcanic lakes and as a gateway to Komodo National Park, home of the largest lizards on Earth. Its population of roughly 2 million is largely spread out across small villages.

Health care facilities, schools, government offices and more than 50 homes were damaged in the earthquake, BNPB said.

Videos posted to social media showed buildings collapsing and panicked residents running and screaming, as dust filled the sky. One video showed damage to a hospital in the village of Aeramo.Epicenter

Theresia Uta, 52, told CNN she had just finished breakfast in the coastal town of Maumere when the earthquake hit. She ran outside and held onto a tree in the yard for 10 minutes, until the shaking stopped.

“Although I have experienced several earthquakes on Flores island before, this was by far the strongest and longest earthquake I have ever experienced. The shaking was extremely powerful and violent,” she said.

She said she quickly got in her car to evacuate, adding that roads have been blocked due to several landslides.

Students at the Roman Catholic St. Peter Major Seminary in the coastal village of Sikka were attending morning Mass when the roof of an assembly hall collapsed, causing people to flee in panic, the seminary’s rector Rev. Guidelbertus Tanga said, according to the Associated Press.

“Our students and nuns ran out in panic beneath a collapsing roof,” Tanga said. “At least one priest suffered a broken leg after jumping from the second floor of a building during the quake.”

A 51-year-old resident of the town of Talibura said the quake was “massive,” and forced her family to rush out of their home.

“The quake was massive, the shock was so strong, we were resting at home with family. There were 13 of us inside the house and we all ran to save ourselves,” the resident, Nona, told the news agency Reuters.

A 16-year-old living in the same area said it was the first time he had felt such a strong earthquake, adding he immediately ran to higher ground.

“I was shocked because of the earthquake. I was sleeping,” Yoan Rinto told Reuters. “Yes, am still panicking, still worrying a lot.”

About 2,000 residents of Nagekeo regency evacuated following the quake, as a precautionary measure, BNPB said.

The agency deployed a helicopter along with its emergency response team, noting that the landscape of the area, which consists of many islands, makes access challenging.

Footage from the national search and rescue agency shared by CNN Indonesia showed rescue workers digging through rubble, searching for possible survivors.

The earthquake in Indonesia followers large-scale disasters in Venezuela and Colombia. In June, Venezuela was struck by two powerful earthquakes, in which thousands lost their lives. Another earthquake that hit western Columbia on Monday has left at least 287 people dead.

An archipelago of more than 17,000 islands, Indonesia is prone to seismic activity and has suffered several devastating earthquakes in the past. The Southeast Asian nation sits on the Ring of Fire, a band around the Pacific Ocean that sets off frequent earthquakes and volcanic activity. The ring is one of the most seismically active areas in the world, spanning from Japan and Indonesia on one side of the Pacific to California and South America on the other.

Another, 6.9 magnitude quake rattled Indonesia just hours later in Northern Sumatra, the United States Geological Survey (USGS) said.

The catastrophic Indian Ocean tsunami of 2004 was sparked when Indonesia’s Sumatra island was hit by a quake with a magnitude of 9.1. The resulting disaster killed more than 220,000 people along the ocean’s coasts, more than half of them in Indonesia.

More recently, hundreds were killed when a 6.9 earthquake hit the island of Lombok in August of 2018. Later that month a trio of intense earthquakes shook several islands in the South Pacific and Indonesia.

And in September of that year, a 7.5 magnitude earthquake and tsunami hit the island of Sulawesi, killing hundreds more. (BBC)
