A strong and shallow earthquake registered by the BMKG as M6.4 hit Bali Sea, Indonesia at 18:44 UTC on October 10 (01:44 LT, October 11), 2018. The agency is reporting a depth of 10 km (6.2 miles). USGS is reporting M6.0 at a depth of 10 km, EMSC M6.0 at a depth of 30 km (18.6 miles).
There are about 3 280 000 people living within 100 km (62 miles).
Some 276 000 people are estimated to have felt moderate shaking, 20 457 000 light and 68 154 000 weak.
At least three people have been killed, authorities said.
The victims in East Java’s Sumenep district perished after being crushed by collapsed buildings, national disaster agency spokesman Sutopo Purwo Nugroho said.
"The earthquake happened early Thursday when they were sleeping and the quake suddenly rocked so they didn’t have time to evacuate," he said, adding that damage caused by the tremor was not widespread.
The USGS issued a green alert for shaking-related fatalities and economic losses. There is a low likelihood of casualties and damage.
Overall, the population in this region resides in structures that are vulnerable to earthquake shaking, though resistant structures exist. The predominant vulnerable building types are unreinforced brick with concrete floor and precast concrete frame with wall construction.
