Antigua warns of gas emissions from active volcano in Montserrat
Shifting winds are blowing sulfurous winds from the Montserrat volcano across the nearby island of Antigua in the eastern Caribbean, prompting authorities there to urge precautions.
Antigua's National Office of Disaster Services is warning those with asthma and allergies to stay indoors. Antigua is about 34 miles (55 kilometres) northeast of Montserrat's Soufriere Hills volcano. Friday's report from Montserrat's government volcano observatory says activity has been relatively low, but the volcano was emitting an average of 368 tons of sulfur dioxide a day over the past week.
Soufriere Hills saw a sizable eruption in 1997 that killed 19 people and buried much of the British territory in ash. As a result, about half the island's 12,000 inhabitants left.

Laguna del Maule volcano (Chile): seismic swarms and ground deformation trigger yellow alert
New signs of volcanic unrest - seismic swarms and ground inflation - have been detected at the volcano recently and SERNAGEOMIN raised the alert level of the volcano to yellow.
A seismic crisis began around February and currently has contained nearly 130 quakes of volcanic-tectonic origin (rock fracturing at depth) as well as fluid movements and volcanic tremor.
What is more worrying is the detection of a notable deformation of the area (inflation at a rate of about 20 cm / year) since the end of January.
The area has not had known eruptive activity during the past 3000 years, and these changes in activity need to be followed closely.
Following the report by SERNAGEOMIN, the government (ONEMI) decided to declare yellow alert for the town of San Clemente yesterday.
