Volcanoes
Authorities in the south of Chile are rehearsing evacuation plans amid concern that the volcano could potentially erupt within "days or weeks."
Villarrica, near the popular tourist resort of Pucon around 750km south of the capital Santiago, was upgraded to an orange alert after it began rumbling and hurling lava into the air late on Tuesday.
The orange alert by the National Geology and Mining Service (SERNAGEOMIN) implies a "significant" increase in activity.
"Three new eruptions of the volcano have been registered, characterized by the disposal of solid and fine ash," Hernando Tavera, director of the Institute, told the agency.
Island residents said that around 10:45 p.m. (20:45 GMT) on Friday, a strong explosion was heard, after which the volcano spewed a column of ash and dust. Two smaller blasts were heard later on the same day.
Lava is actively flowing down the volcano's western slope. Witnesses say the lava can be seen several miles away from the volcano.

The volcano, which had remained dormant for more than a century before the latest explosion, blasted a mass of ash and volcanic debris ten miles into the sky, reaching a layer of the atmosphere known as the stratosphere.
Just under two weeks later, the Ulawun volcano in New Guinea erupted, sending ash nine miles into the sky and causing 15,000 people to evacuate.
Comment: Less than a week ago an eruption at Kamchatka volcano (Shiveluch) in Russia fired ash 70,000 ft (21.3 km) into the stratosphere.
Sulfuric gas from both of these eruptions reached the stratosphere, which is why skies in some parts of the world turned oddly purple as the Sun started to set.
This is because fine volcanic aerosols in the stratosphere cause blue light particles to scatter.
When the scattered blue particles combine with the normal red hue of a sunset, it makes an eerie purple glow.
Italy's Stromboli volcano has exploded in front of holidaymakers, spewing an ash cloud high into the air and sending a river of lava into the sea.
It comes almost two months after a massive eruption killed a man and forced terrified tourists to dive into the sea.
The summit of Stromboli - one of the most active volcanoes in the world - had already been closed due to an increase in activity this summer, including smaller explosions this week.
Largest eruption in more than a decade occurred in Russia on the Kamchatka Peninsula with Shiveluch pushing ash to 70,000+ feet. This will for sure have a regional cooling effect along the latitudes along 50-60N and at the same time the Canadian SIPS put out the long rage forecast for a blocking high that will deflect cold Arctic air all winter south over N. America, Asia, and Europe. This is it, the feedback loop is in full play. Coldest in two centuries on our door step as we step down further into the Grand Solar Minimum.

The recent strong explosive activity at Kamchatka (Shiveluch) volcano, Russia climaxed over the weekend as a VEI 5/6 monster of an eruption rocked the mountain, and there's likely more to come.
The Volcanic Ash Advisory Center (VAAC) Anchorage reported on a volcanic ash plume rising to a staggering 70,000 ft (21300 m) and moving at 10 kts in NNE direction — particulates ejected to altitudes above 32,800 feet (10km), and into the stratosphere, have a direct cooling effect on the planet.
This eruption at Shiveluch produced a "huge stratospheric injection" says Diamond, of the Oppenheimer Ranch Project. "We're talking Plinian, Ultra-Plinian — one of the largest eruptions of the last decade."
"This baby is not over."
Shiveluch is an unstable stratovolcano with a recent eruptive history littered with VEI 4s and 5s. But even still, this year's activity, culminating with this weekend's big boom, represents a tremendous uptick.
Stay tuned for updates.

The sea of pumice - the size of 20,000 football fields - was first reported by Australian sailors earlier this month.
Experts say the mass likely came from an underwater volcano near Tonga which erupted around 7 August according to satellite images.
Sailors have been warned to stay clear of the potential hazard.
Pumice is a lightweight, bubble-rich rock that can float in water. It is produced when lava goes through rapid cooling and loss of gases.
Comment: People are weird. If it's something ambiguous, like maybe the planet warmed 0.2 degrees over the last decade, they say this definitely spells doom (unless people pay 'green' taxes, which will magically prevent the doom from happening), but when it's a clear sign of significant geological activity taking place right now, they brush it off as being a welcome positive?!
Pumice islands the size of small countries forming from recent undersea volcanic eruptions are not a good sign. Not for civilization anyway. And certainly not for coral reefs, which have been acidified to death by all the outgassing that has accompanied these eruptions...
