Two quakes struck in quick succession off the southern coast of Indonesia’s Sumba island on Tuesday morning, sending startled people into the streets for safety.
A shallow and moderately strong 5.9 quake struck at 06:59 WIB, around 40 kilometers (25 miles) off Sumba, an island of some 750,000 people, the United States Geological Survey said.
It was followed up some 15 minutes later by a stronger 6.0 magnitude quake in the same area at a depth of 30 kilometres.
As posted on its Twitter account, Indonesia’s Meteorology, Climatology and Geophysics Agency (BMKG) recorded the first quake at 6.0 and the second one at 6.3.

No tsunami warning has been issued, nor was there any immediate reports of serious damage.
“We felt four shakes. People were panicking when the first quake happened and ran out of the hotel, about 40 of our guests,” Defis Rinaldi, a worker at the Padadita Beach Hotel told AFP by telephone.
“It was only a few seconds and the geophysics agency didn’t issue a warning, everything is back to normal now,” he said.
Sumba lies some 1,600 kilometers south of Sulawesi island which was struck by a devastating quake and tsunami on Friday, killing more than 800 people.
