The alert level for the volcano has been raised to yellow two days ago. This doesn’t mean that an eruption is expected to occur in a near future, but acknowledges that the volcano is currently preparing itself for its next eruption, which will come, sooner or later, but currently without possibility to indicate a specific time frame.
The Hawaiian Volcano Observatory (HVO) reported that “for the past several months, earthquake and ground deformation rates at Mauna Loa Volcano have exceeded long term background levels. An eruption is not imminent and current rates are not cause for alarm. However, they do indicate changes in the shallow magma storage system at Mauna Loa.”

Fog or freezing fog patches will quickly become more widespread later on Christmas Eve, and will also be dense in places. Not everywhere will see fog, but where it does form, the visibility may fall to around 50 metres at times. Fog will tend to thin and lift in western and some central areas of England overnight, but will be slow to clear on Christmas Day in the east, perhaps persisting for much or all of the day in parts of Eastern England.

An island volcano on the north coast of Papua New Guinea erupted early on Saturday, forcing 2,000 villagers to flee from lava flows, the National Disaster Centre said.
Manam Island, just 10 km (6 miles) wide, is one of the Pacific nation’s most active volcanoes and is home to roughly 9,000 people.
Three villages were directly in the path of the lava flow and residents had to be evacuated to safer ground, Martin Mose, director of the PNG National Disaster Centre, told Reuters by phone.
The Rabaul Volcano Observatory (RVO) reported the eruption began at 6 a.m. local time (2000 GMT Friday), sending an ash column 15 km (50,000 feet) above sea level.
The ash falls were so heavy that trees broke under the weight, the RVO said in an information bulletin.
“The most affected areas are Baliau and Kuluguma and due to the very poor visibility caused by the ash fall, people are using torch light to move around,” it said.
The RVO’s Steve Saunders said it was an unusually large eruption.
“There are no casualties as far as we know but we are telling people to keep away from valleys for risk of mud flows … there’s a heavy thick blanket of ash on the flank and if there is heavy rainfall, we are making people aware of the threat,” he said by phone.
Saunders said the initial phase of the eruption was over but a new vent had opened, indicating more activity may be likely.
The Darwin Volcanic Ash Advisory Centre (DVAAC) issued a threat warning to aviation to reroute around the cloud, which was above the cruising level of commercial airlines.
The cloud was expected to dissipate over the next 12 hours, DVAAC meteorologist Amanda Alford told Reuters.
Previous eruptions on Manam have killed residents who breathed in the ash or were buried by landslides, according to volcanic information website volcanodiscovery.com.
