A spokesman for Indonesia's National Disaster Management Board issued a statement that said the quake was felt in Mataran, Lombok's capital, as well as Sumbawa Island, to the east of Lombok, the New York Times reported.
The travel agency is working with customers now in or set to travel to Lombok to help them adjust and rebook their travel arrangements, she said.
'MASSIVE quake, oh my god, ' she wrote.
Last month, an natural disaster with a magnitude of 6.4 struck 1 km southwest of Lombok, killing 16 people and injuring many others.
A magnitude 7.0 quake struck off the north coast of Indonesia's island of Lombok on Sunday, according to the US Geological Survey.
The quake caused light damage as far away as the Javanese city of Bandung, some 955 kilometres from Mataram, but was felt strongly on the neighbouring resort island of Bali.
Indonesia is located in the Ring of Fire, an area in the basin of the Pacific Ocean, which is vulnerable to frequent earthquakes and volcanic eruptions.
In 2004, a devastating tsunami triggered by a magnitude 9.3 undersea natural disaster off the coast of Sumatra in western Indonesia killed 220,000 people in countries around the Indian Ocean, including 168,000 in Indonesia.
The Bali and Lombok airports have stayed open.
"Our assessment is that people in Lombok really need shelters at the moment, especially tarps and blankets".
Chrissy Teigen who is vacationing in nearby Bali witnessed the natural disaster first hand from relatively safe distance.
"I was at the rooftop of my hotel and the building started swaying very hard".
She wrote: "I'm either still trembling or these little quakes won't stop". "We predict the highest wave levels to be only one-half a meter", she said.
In his post, Mr Shanmugam said that he is now waiting for a flight out of Lombok and thanked everyone for the kind thoughts and prayers.
"All the activities are shut down".
Indonesia's Ministry of Tourism released a statement saying no tourists had been "injured or impacted" by the quake. Some of them said their own houses had been destroyed but they were still helping us".
Some airlines added extra flights to help tourists leave the island, while about 1,200 foreign and domestic tourists were evacuated by boat from three Gili islands off Lombok's northwest coast, said Nugroho.
Home Affairs Minister K.Shanmugam of Singapore described the quake on Facebook as it shook violently the bulding in which he was staying. "I could not stand up", said Gino Poggiali, a 43-year-old Frenchman, who was with his wife and two children at the airport.
Speaking from a beach as he awaited evacuation, he said: "There was rumbling and then all the power went off".
Nugroho told a news conference damage was "massive" in the north of Lombok.
The Bali and Lombok airports continued operating on Sunday night, according to the director general of civil aviation. He says the quake "was powerful enough to put us on the floor" and cut power.
"We understand there are other areas that are worse hit but I hope they can get the aid here soon".
