There is a big difference between a fissure 25' wide forming in 3 weeks and a rift 5 miles wide forming in a day.
Think about it, it makes no sense. That much earth movement in such a short period of time would create huge earthquakes.
It appears to be an error in translation. I would venture that the Peruvian officials said something like, "The eruption did not occur in Puyehue volcano but in the rift area four kilometers from it." The press; "Whoa! a rift! The eruption caused a huge rift!"
Puyehue-Cordón Caulle volcano in Central Chile is a complex of 2 volcanoes: Puyehue volcano and the fissure system of Cordón Caulle. Puyehue volcano has a 2.4 km wide summit caldera, but historical eruptions occurred at the Cordón Caulle rift zone.
The Cordón Caulle geothermal area occupies a 6 x 13 km wide depression and is the largest active geothermal area in the southern Andes.

"I ask all the population (in designated areas) to evacuate as soon as possible, because ... human life could be at risk," said Juan Andres Varas, regional governor of Los Rios, Chile.
In a statement posted on the Los Rios government's website Monday, he said volcanic material and potentially toxic gases were slowly advancing toward the nearby Nilahue Valley. edition.cnn.com...

Although the eruption has been attributed to the Puyehue volcano, it is not clear if it is restricted to this volcano or if it extends to the Caulle Mountain Range, an adjacent volcanic fissure. The Caulle complex has erupted many times in recorded history. The last eruption occurred in 1960 causing widespread destruction, while the Puyehue volcano has remained dormant longer.

Someone had mentioned the split that occured in Eritiea. and had looked at a map and this is the most logical expansion of that rift!
Please do explain how that could be a logical expansion of this rift zone?
I am waiting to be educated since obviously many years of geography and geology have done nothing for me.
Edit: Here is a map to help you with the 'logic, reality and common sense'.

All these Earthquakes and Rifts.........pause for thought.....how off the wall is the Expanding Earth Theory?
Didn't read all the thread I'm about to go through it.....Did we get any pictures? I should imagine pictures of the rift might be too great a task while the Volcanoes are so active, Pyroclastic Clouds and such.
Imagine if the Mid Atlantic Ridge did the same? Very interesting times
I don't know if meteorologists even study volcanic eruptions.

I'm not a meteorologist, so I'm wondering if anyone on ATS knows what natural mechanism is in play that is generating those electrical discharges. I imagine it's related to the force of the eruption and ash cloud.
Here is a description from Ian O’Neill from Universe Today: “As the hot ash rises through the cooler atmosphere, transfer of charge occurs. This excess of electrons within the cloud makes it act like a capacitor, and should the conditions be correct, huge electrical discharges may be observed as bolts of lightning during volcanic eruptions.
According to at least one scientist, it's not increasing at such a slow rate, and he thinks it's related to global warming (though apparently not man-made global warming, but the natural kind):

I don't know if he's right or not, but he makes an interesting case, and the data I've seen seem to support some kind of increase in both global temperatures and major earthquakes.
The analysis of more than 386,000 earthquakes between 1973 and 2007 recorded on the US Geological Survey database proved that the global annual energy of earthquakes on Earth began increasing very fast since 1990."...Increase in the annual energy of earthquakes is the strongest symptom yet of planetary overheating.
"NASA measurements from space confirm that Earth as a whole absorbs at least 0.85 Megawatt per square kilometer more energy from the Sun than it is able to radiate back to space. This 'thermal imbalance' means that heat generated in the planetary interior cannot escape and that the planetary interior must overheat. Increase in seismic, tectonic and volcanic activities is an unavoidable consequence of the observed thermal imbalance of the planet," said Dr. Chalko.
An erupting Chilean volcano sent a towering plume of ash across South America on Monday, forcing thousands from their homes, grounding airline flights in southern Argentina and coating ski resorts with a gritty layer of dust instead of snow.
Booming explosions echoed across the Andes as toxic gases belched up from a
three-mile-long (five-kilometer long) fissure in the Puyehue-Cordon Caulle volcanic complex — a ridge between two craters just west of the Chilean-Argentine border that began erupting Saturday
....Enrique Valdivieso, the director of Chile’s National Geology and Mines Service, said the fissure was belching toxic gases and material that could clog rivers and force them to overflow.
A rift more than six miles (10 kilometers) long and three miles (five kilometers) across was torn in the earth's crust, officials said Saturday night.
