A warning sign blocks the road to Bardarbunga volcano, some 20 kilometres (12.5 miles) away, in the north-west region of the Vatnajokull glacier August 19, 2014
Seismic activity in the Bardarbunga vicinity has not been decreasing, the Icelandic Meteorological Office reported on Thursday.
"The highest magnitude during the last 24 hours was about 3.8, measured at 23:38 last night (20th August)", the agency's statement said.
There were around 1,000 small earthquakes detected in the area Wednesday that prompted the evacuation of about 300 tourists.
"The area is now closed and has been evacuated," Iceland's Civil Protection Authority said on its website. "These actions were taken following seismic activity around the Bardarbunga caldera in the last few days."
The agency also said it would carry out further air patrols over the volcano to make sure no one was left there.
If the volcano doe start to erupt, it would lead to the Vatnajokull glacier which sits over it melting.
