Boas,
Achei por bem abrir um tópico com esta questão para além de acompanharmos a situaçõa poderemos discutir a sua relação e interferência com o clima não só local como regional e que sabe se mundial, isto dependendo da sua intensidade pq este monstro promete!
(espero que não)

Imagem Merapi:
http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13538
Nas últimas semanas parece que existiu uma actividade vulcânica fora do normal, senão vejamos:
Merapi in Java, Indonesia
Status: Emitting small lava flows of up to 100m from the crater. Plumes of white smoke rising up to 800m
Notes: Merapi is one of Indonesia's most active volcanoes. The current cycle of activity began in early April. The volcano could be close to a major eruption event.
Imagem Ubinas impressionante:
http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13560
Ubinas in Peru, South America
Status: Explosion on 22nd April that produced gas & ash plume up to 3kms high. Traces of ash travelled up to 60kms from the volcano. Explosion accompanied by earth tremors. Activity subsided from 26th April.
Notes: Ubinas is Peru's mostactive volcano. Activity documented since the 16th century.
Barren Island in the Andaman Islands - Indian Ocean
Status: Plume of gas/ash rose up to 3.7kms on May 2nd. Plume was imaged by satellites.
Notes: Barren island is 3km wide. The volcano rises from a depth of 2250m below the surface to 354m above it. The caldera is 2kms wide.
Bulusan in Luzon, Philippines
Status: Explosion at Bulusan on 29th April. Ash plume rose up to 1.6kms and dropped ash on surrounding villages. There is now a4km exclusion zone around the volcano.
Notes: Intermitemtn explosions have been recorded at Bulusan since the 19th century.
Galeras in Colombia, South America
Status: Partially solidifeid lava dome in the crater with low levels of seismic activity at present. Possible moderate eruption likely in days or weeks. One to watch!
Notes: This volcano has been active for more than 1 million years. It is west of the city of Pasto.
Karymsky on the Kamchatka Peninsula, E Russia
Status: low-key eruptions continue to take place. Ash plumes rising up to 3.8kms. Satellite imagery show a thermal 'anomaly' at the crater, suggesting some molten lava present.
Notes: The volcano has a 5km wide caldera. Eruptive activity is ongoing since 2005.
Kilauea in Hawaii, USA
Status: Subterranean lava continues to flow into the ocean to create a lava 'bench'. The bench has grown to 44 acres since Nov 28th and is highly unstable. Submarine landslides are likely to collapse it into the sea. The bench is now at its largest for 23 years.
Notes: the lava flowing into the sea creates semi-permanent steam plumes along the coastline. Activity can be viewed on this webcam http://hvo.wr.usgs.gov/cam/
Manam in Papua New Guinea
Status: Ash cloud found on satellite imagery on 28th April. The plume rose to 3kms high.
Notes: Eruptions recorded at Manam since 1616.
Sakura-Jima in Kyushu, Japan
Status: Explosions on 28th April and 1st May. Both produced plumes of ash, the first od which rose to 2.1kms
Notes: One of japan's most active volcanoes. A webcam of the volcano is here http://373news.com/sakucap/index.htm
San Cristobal in Nicaragua, Central America
Status: gas and ash plumes sighted on 21-23 April. Small ash deposits on nearby towns.
Notes: San Cristobal is Nicaragua's highest volcano.
Soufrierre Hills in Montserrat, Caribbean
Status: Lava dome growing. Small rockfalls, ash venting and some minor pyroclastic flows ( for pyroclastic flows read hot ash, gas, pumice and rock avalanche - these can reach speed of up to 70 miles an hour) on the East side. The ground temperature on some areas of the mountain on the east side is 400c. Some earth tremors and moderate sulphur dioxide in the atmosphere near the crater.
Notes: This is the one that exploded into life in 1995 after a long dormant period.
St Helens in Washington State, USA
Status: Lava dome growing. Some small emissions of gas, steam and minor but frequent (every few minutes) earth tremors.
Notes: The 1980 eruption removed 400m of the top part of the volcano by way of a slope failure. The webcam is here http://www.fs.fed.us/gpnf/volcanocams/msh/
Tungurahua in Ecuador, South America
Status: Small to moderate explosions between 28 April and 1st May. Gas, steam and ash rose from the volcano. The plume reached 2kms high on Apriul 28th.
Notes: This volcano is 3kms high. It sits 140kms south of the Ecuador capital. It sprang into life in 1999 after a dormant period of more than 70 years
