What it's like to visit an active volcano
When I look at the pictures and video from my research trip to Chaitén Volcano in Northern Patagonia, Chile, I remember the reality as being so much more. Seeing the volcano's steam vents, hearing the mountain crackle and rumble, watching the plume build into gigantic cumulonimbus-like clouds while standing in a valley that was devastated by a pyroclastic flow was an incredible experience.
Chaitén Volcano came to life for what many believe is the first time in 9,000 years on May 2, 2008, with what scientists consider a major eruption. The plume ascended 19 miles into the stratosphere, covering much of Patagonia with volcanic ash, and drifting as far east as the Atlantic.
The town of Chaitén lies six miles from the volcano at the mouth of the Rio Blanco. Chaitén was evacuated at the start of the eruption, with no loss of life. Heavy winter rains ten days later washed the ash that covered the denuded mountains into the river, creating a lahar that caused the banks of the Rio Blanco to overflow. 90% of the town was flooded. Over subsequent weeks, the river excavated a new course through Chaitén, destroying a significant part of the town, as this aerial shot shows.
One year later, the volcano continues to erupt. According to this excerpt from the most recent bulletin from Servicio Nacional de Geología y Minería (SERNAGEOMIN), the Chilean government agency charged with monitoring volcanic activity in that country:
The eruptive activity continues with the growth of the dome complex. Consequently the latent danger of collapse because of the growth of the domes continues, with possible explosions and generation of block-and-ash flows, which may affect the valleys adjacent to the volcano. In consequence, SERNAGEOMIN suggests maintaining Volcanic Red Alert.Given the seriousness of the threat, it's no wonder Chaitén town remains empty. And yet despite the danger, approximately 50 of the original 4,500 residents still live in the town, though Chaitén is without electricity and running water. Residents get their water from clean streams, purchase gasoline for their vehicles and generators from towns 100 miles away. Several stores supply residents' needs, stocked with goods brought in by ferry.
Last April, my son and I stayed 4 days in Chaitén. Our guide, Nicholas La Penna, has been conducting tours for visitors to the area for a dozen years, and was helpful beyond measure. The rooms and meals he arranged for us with a friend who rents cabins were far more comfortable than I'd anticipated. Cabanas Pudu has its own well, so unlike most of the town's residents, we had the luxury of cold running water and indoor toilets. Electricity was generated between 7 - 10 every evening, which meant I didn't need the extra batteries I'd brought for my electronics. After a day trekking about in the cold and rain, our two-bedroom cabin was cozy and warm thanks to a fire Juan made for us in a small woodstove each evening. And Anita's meals were fabulous - salmon, chicken, beef, potatoes, rice, fresh bread, and salad. Just look at this breakfast!
Which we very nearly didn't.
Normally, the volcanic plume is visible from Chaitén. This is the sort of vista I expected to see:
Or perhaps this:

(This is the famous photo of the May 2, 2008 eruption taken by Carlos Gutierrez that brought Chaiten Volcano to my and most of the world's attention.)But late April is early winter in the Southern Hemisphere, and the weather was persistently rainy and overcast.
When the last day dawned more of the same, I had to reconcile myself to the idea that while I was now just 6 miles from Chaitén Volcano (after traveling 7,000), I might not get to see it.
Hoping the weather would improve, we headed out nonetheless. This is a view of the northern end of the Carretera Austral, the main north-south road in this part of Chile.
As you can see in this photo, the trees nearest to the volcano are simply gone - incinerated during the initial eruption. Farther away, the trees have been knocked down. Where we're standing less than a mile from the lava dome, the trees were stripped of their leaves and secondary vegetation by the initial blast of debris and hot gasses and have never recovered. Ferns and mosses are beginning to reclaim the area, but aside from these, I could have been shooting my pictures in black and white.
So how does one pose in front of an active volcano? Serious, or smiling? I tried both.
The bridge railing on the side facing the volcano is twisted and bent, while the other side is undamaged - a vivid reminder of the tremendous forces that swept through this valley.
Nicholas had warned from the outset that we wouldn't stay long near the volcano - it's just too dangerous. He also said he won't bring casual sightseers here. I'm grateful he felt my writing a novel featuring Chaitén Volcano was valid enough reason to come.People ask if I was afraid. I can honestly say that I was not. While I knew another pyroclastic flow was very real possibility due to the instability of the lava dome, I figured the odds of such an event occurring while I happened to be there were relatively small.
Instead, I felt nothing but awe. There's a sense of enormity in the presence of an active volcano, a keen awareness of forces unimaginable that's difficult to convey. To be in an area of both destruction and creation and observe firsthand the forces that shaped much of our earth engenders a feeling approaching reverence. I understand now why the ancients worshiped volcanoes.

Near the end of our stay, we saw colors in the clouds - orange and brown - evidence of pyroclastic activity within the caldera.
It's hard to imagine any research trip I might take in the future that could possibly top visiting an active volcano - unless perhaps I decide to write a thriller about a lunar landing gone wrong!
