#YellowAlert Issued Due To Increased #SeismicActivity At #MaunaLoaVolcano In #Hawaii

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.

Storm and snowstorm alerts for all of North and South Iceland

Storm Alert
The Icelandic Meteorological Office has issued Yellow Weather Alerts, warning of severe gale in South Iceland and snowstorm in North Iceland today Wednesday and tomorrow Thursday. Travelers should make appropriate revisions to their travel plans.
 
Gale or severe gale, with hazardous wind gusts and localized winds near steep mountains in South Iceland can pose danger to travelers driving cars susceptible to wind. We have already seen one RV blown off the road in the season’s winter storms.
 
Meanwhile a snowstorm is headed for North Iceland. Gale force winds, heavy snowfall and blowing snow can create whiteout conditions while ice and the snow will reduce traction, making roads dangerously slippery. Stronger localized winds can create hazardous conditions for vehicles susceptible to wind.
 
The weather alert for South Iceland, including the entire South Coast is in effect from 15:00 (3 pm) today, Wednesday September 3, until 23:00 (10 pm), and for South East Iceland, from the village of Vík to the town of Höfn east of Jökulsárlón glacier lagoon from 17:00 (5 pm) today until 01:00 (1 am).
 
Travelers should prepare for gale or severe gale with sustained wind speed of 15-25 m/s (33.5-56 mph). Localized winds, especially near steep mountains, can reach 35 m/s (78 mph). Such winds can be hazardous to vehicles that are susceptible to wind. 
 
Snowstorm alerts for the northern part are in effect for the Westfjords from 22:00 (10 pm) tonight until 14:00 (2 pm) tomorrow, Thursday September 4, for North East Iceland from midnight until 1:00 in Friday morning, and for North West Iceland from 4:00 (4 am) until 22:00 (10 pm) tomorrow evening. A northeasterly severe gale and localized winds which can reach hurricane force (35 m/s), with snowfall, sleet and rain. Winter driving conditions on roads at higher elevations
 
Note that ICE-SAR has advised people to postpone travel
ICE-SAR has warned travelers that due to the snowstorm there will be very difficult or no travel conditions in all of Iceland north of Borgarnes town in West Iceland and Egilsstaðir in East Iceland, while there are difficult or no travel conditions in South Iceland from Selfoss eastward. The only part of Iceland which seems to be spared the full force of the storm is the South-West, including the Capital Region and Reykjanes peninsula.

Papua New Guinea volcano erupts, forcing villagers to flee

Volcano Alert

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.
