Volcanoes
Almost 7,000 miles away in Mexico, the Colima volcano blew its top after a period of relative calm. A steam and ash cloud rose two miles into the sky and the grumbling of the mountain could be heard in towns a few miles away.
In Guatemala the 'Fire Mountain' belched out lava and sent up a moderate ash cloud causing an ash fall over nearby towns. The explosions and shock waves occurring in the volcano can be felt by residents over 6 miles away. Doors and windows are reported to be rattling, but there has been no damage so far.
In Vanuatu the Yasur volcano is giving some cause for concern. Although the explosions are quite weak the continuous ash that is coming from the mountain is starting to build up on farming land.

Smoke billows from the Mount Etna, Europe's tallest active volcano, Sicily, Saturday, Nov. 23, 2013.
The eruption Saturday did not force any evacuations, but a highway was closed for half an hour as a precaution. Authorities also briefly closed two of four air corridors serving the nearby Catania airport but air traffic was not interrupted.
Etna erupts occasionally. Its last major eruption occurred in 1992.

The erupting volcano off Nishinoshima island in the Ogasawara archipelago, Japan, an area rich with mineral resources.
Plumes of smoke ash billowing from the 200-metre island can be witnessed through a video. "Smoke is still rising from the volcanic island, and we issued a navigation warning to say that this island has emerged with ash falling in the area", said a spokesman for the maritime agency.
Weak explosions at Yasur: Geohazards reports that the volcano continues to produce near-continuous ash emissions while explosions are relatively weak at the Yasur volcano on Vanuatu. This phase of ash emissions began on 3 November and are likely to continue into the coming days and weeks. Yasur Alert Level is still maintained at Level 1. Villages and communities located close and far away from the volcano, especially those in the prevailing trade winds direction (NW) are likely to receive ash falls. - Volcano Discovery
Yesterday at 21:45 hours this morning between 8:00 and 8:30 am, the volcano emitted two strong exhalations heard that reached in the communities closest to the "granite colossus," mainly in the municipalities of Comala and Cuauhtémoc. From the city of Colima there was a big cloud of steam that rose to just over 2 miles. The chief operating officer of the State System of Civil Protection, Melchor Ursua Quiroz, said: "The volcano has been recharged" and in the last two days has been sharp exhalations, which triggered an alert status from monitoring equipment installed before this new volcanic activity.

Mount Sidley is the youngest volcano rising above the ice in West Antarctica's Executive Committee Range. A group of seismologists has detected new volcanic activity under the ice about 30 miles ahead of Mount Sidley.
The discovery finally confirms long-held suspicions of volcanic activity concealed by the vast West Antarctic Ice Sheet. Several volcanoes poke up along the Antarctic coast and its offshore islands, such as Mount Erebus, but this is the first time anyone has caught magma in action far from the coast.
"This is really the golden age of discovery of the Antarctic continent," said Richard Aster, a co-author of the study and a seismologist at Colorado State University. "I think there's no question that there are more volcanic surprises beneath the ice."
The volcano was a lucky find. The research project, called POLENET, was intended to reveal the structure of Earth's mantle, the layer beneath the crust.
In 2010, a team led by scientists from Washington University in St. Louis spent weeks slogging across the snow, pulling sleds laden with earthquake-monitoring equipment.
- The volcano in Sicily erupted violently on November 11 and has created hundreds of smoke rings that travelled east
- Volcanologist Dr Tom Pfeiffer, who photographed the phenomenon, believes they were produced by a circular vent
- It is not the first time Etna has managed to produce the smoky halos
The volcano erupted violently on November 11 and since then has produced regular explosions, as well as hundreds of perfect vortex rings.
While theories abound, scientists are not entirely sure why the volcano is able to blow the circular puffs of steam - although some think a circular vent could be the cause.

Volatile volcano Mount Etna has been blowing perfect smoke rings after erupting violently on November 11 and has since produced regular explosions, as well as dozens of perfect vortex rings

A photo of Mount Sinabung in North Sumatra, Indonesia, before its latest eruption forced thousands of nearby residents to flee.
More than 5,000 people have been evacuated from towns and villages in North Sumatra's Karo Regency since Mount Sinabung awoke in October after a three-year dormancy. Karo is an agricultural region that supplies vegetables for surrounding islands.
The evacuation and devastating ash fall have affected crop harvests, leading to higher prices on vegetables and chilies elsewhere in Indonesia, according to the Jakarta Post.
The Indonesian Center for Volcanology and Geological Hazard Mitigation warned people not to approach within 2 miles (3.2 kilometers) of Mount Sinabung.
On Monday (Nov. 11), a pyroclastic flow, a fast-moving avalanche of ash, lava fragments and air, was seen racing down the peak. Since then, the volcano has blasted out one to two ash explosions every day. Lava has flowed more than 1,000 meters (3,200 feet) from the top of the volcano.
According to sources, the military helped to evacuate about 1,293 people from four villages, surrounding the volcano. It has also been revealed by the sources that in the month of September about 14,000 people were forcibly evacuated, after the recognition of the activity signs of the volcano.
Sinabung is the world's fourth most populated country and it comprises of nearly 130 active volcanoes. These volcanoes in Sinabung straddle the "Pacific Ring of Fire".
