Indonesia earthquake: Rescuers battle aftershocks as survivor search continues
West Java governor Ridwan Kamil told the BBC that the region had experienced around 140 shocks since Monday's quake, Qazet.az presents.
At least 268 people, including many children, have died so far. Around 151 people remain missing and more than 1,000 are injured.
Hundreds of responders have been sent to Cianjur to accelerate the rescue.
But their efforts have been stymied by torn-up roads and continuing tremors.
Mr Kamil told the BBC's Newsday programme that the local community was still exposed to these aftershocks, which have in some cases put responders at risk.
"The follow-up earthquake [sic] is still happening," he said, but added that he hoped these would come to a stop by Friday. "Currently we are coordinating [our mission] to focus on search and rescue...[as] many people are still missing mostly in remote [hilly] areas [and] mountain tops."
Mr Kamil told the BBC rescue teams are still traversing the ground on foot and motorbike, with road paths not always accessible, but that they also had helicopters on standby to transport found victims to hospital.
The 5.6 magnitude earthquake struck near the heavily populated town shortly after lunchtime on Monday, reducing scores of buildings to rubble.
