Less than a week after an earthquake killed 16 persons in Lombok, Indonesia, another 7.0 magnitude earthquake  on Sunday rattled the same popular tourist island located near Bali, killing at least 91 people.

According to the country’s National Disaster and Mitigation Agency, dozens more have been injured while thousands of people have been evacuated from buildings to outdoor 

The United States Geological Survey said most of the victims of the earthquake which struck on Sunday evening at a depth of 10.5 kilometres were killed by falling rubble.

Patients had to be evacuated and treated outside a hospital in Lombok’s main city of Mataram after electricity was knocked out across the island which is a popular tourist destination.

Spokesperson for the Disaster Mitigation Agency, Sutopo Purwo Nugroho said authorities believed the quake may have caused damage in the city of Mataram, on Lombok’s western coast.

Singapore’s Law and Home Affairs Minister, K. Shanmugam, who was in Mataram at the time of the quake, wrote on his Facebook page that his 10th-floor hotel room shook violently and walls cracked.

“It was quite impossible to stand up. Heard screams. Came out, and made my way down a staircase, while building was still shaking. Power went out for a while. Lots of cracks, fallen doors. Thank you for your concern – we’re all fine – a bit shaken up,” Shanmugam wrote.

Lombok and Bali are famed for their pristine beaches and mountains, with local planning restrictions in both locations prohibiting construction above the height of coconut tree.

Sitting on the Pacific ‘Ring of Fire’ where tectonic plates collide and many of the world’s volcanic eruptions and earthquakes occur, Indonesia is one of the most disaster-prone nations on earth.

In 2004, a tsunami triggered by a magnitude 9.3 undersea earthquake off the coast of Sumatra in western Indonesia killed 220,000 people in countries around the Indian Ocean, including 168,000 in Indonesia.
