What is a volcano, why would you want to see one, and how do you pronounce Fagradalsfjall?
Published on Thursday, 27 July 2023.
I did not plan on this being my inaugural post for the new website blog.
I had some other articles planned.
I originally thought about only one post for this trip.
During the trip I realized so many people from my friends and family on social
media were watching, rooting, and pushing for Hope and I that I felt the full
story should be shared.
This story is being presented in multiple parts.
I was exposed to volcanoes while growing up by my grandparents. They worked at the local school
and brought home books and videos on science and the earth. For whatever reason the images of
glowing lava and mountains of fire got stuck into my developing toddler brain. By the age of 5
I could tell you about most of the volcanoes on the planet. I didn’t spend time making friends,
I read books, drew pictures, and daydreamed about volcanoes.
In retrospect it was a
screaming indicator that I had wicked ADHD and some form of a social disorder.
My grandparents, free in the summer, took me on road trips to places like Mount Saint Helens,
Craters of the Moon, and Yellowstone. By the time I went to middle school I had been to several
volcanoes, but none which were erupting (though I did see the red glow of Kilauea through the clouds
from a plane in 2011).
As growing children tend to do, my attentions shifted (though not to anything remotely considered "normal"). Volcanoes segued to
caves and then took a hard turn to engineering and math (specifically related to rocketry and aerospace).
I went to WVU for a degree in Mechanical and Aerospace Engineering, found the caving club, and promptly had a
personal crisis.
One of my grandparents got very sick, I also realized I wanted to be an
engineer but really wanted to be a photographer, and then that whole ADHD-social problem blossomed into a flower of chaos.
College was rough. I graduated, barely, after five years of studying and also building a career as a photographer.
Then the pandemic hit, my engineering job ended unexpectedly, and I found myself unemployed and completely burnt out.
For twenty years or so I was ignoring that early fascination with volcanoes.
I had flirted with the interest off an on. I was inspired by the book Volcano Cowboys which details the evolution
of the science of modern volcanology. As a caver, I could appreciate it. For several years I was a geyser gazer
in Yellowstone, part of a group of citizen scientists observing and documenting the thermal features of Yellowstone.
Geysers are obviously similar to volcanoes in their general gestalt. Every few years I'd get on a strong volcano-kick before
reminding myself that my life had gone a very different direction and I would force myself to go back to reality.
Then this volcano erupted in Iceland. For weeks I watched with a mixture of awe and nausea as thousands of
people got to live a dream that I wanted to live. The years of travelling for caving expeditions made me realize that most any
part of the world was within reach. Suddenly, volcanoes were not in some exotic far-flung corner of the world - this one was only a
six hour plane ride and a thirty minute walk from me.
Of course, now I couldn’t because of *waves hands wildly* everything. I missed this boat. Trying to see ephemral events in
Yellowstone taught me the lesson that ephemeral natural events do not come to you, you must go to them.
I even knew people personally who went there just for a weekend to watch it. It was the definition of envy.
It also reignited this inner desire in a way I could no longer ignore.
What is a volcano?

If you’re familiar with just what a volcano is, you may want to skip
ahead to where I start talking about this specific volcano – or you
could read on and scrutinize my words. As always, if you disagree
with something send me a message and I’d love to chat. I update this
website routinely and prefer technical accuracy.
A volcano is a rupture in the crust of a planetary-mass object that
allows hot lava, volcanic ash, and/or gases to escape from a magma
chamber below the surface.
[1][2]
When a volcano is actively expelling the innards of the Earth, it is erupting.
Our history is intertwined with volcanoes. For millennia humans have
sought out the fertile soils which build up around them. The coffee you
enjoy in the morning was likely grown within proximity to an active
volcano. The wine you like from Italy also came from grapes grown in
volcanic soil. Rice, pineapples, corn, eucalyptus… all are grown around
volcanoes.
This causes civilization to move closer and closer to the volcano itself
– the closer you get, the better the soil. In the case of volcanoes
which go centuries between erupting generations will resides ever closer
to a mountain that they have long forgotten is a volcano. The results
are frequently quite deadly such as Pinatubo in 1991,
Lamington in 1953,
and Nevado Del Ruiz in 1985,. The same behavioral pattern is setting up
the Pacific Northwest for a major disaster when Mt. Rainer next erupts. [3]
Where do volcanoes form?

Volcanoes typically form at plate boundaries, where large sections of the Earth’s
crust (plates) move towards or away from each other. In some locations a plume of magma rises from within the mantle in the middle of a plate
and form a hotspot. These hotspots generate volcanic activity far away from plate boundaries.
The middle of the Atlantic Ocean is one such place where plates are pulling apart. Down the middle of the Atlantic
Ocean is the Mid-Atlantic Ridge, a underwater mountain range formed by magma coming
up through the opening cracks.
Near the northern end of the Mid Atlantic Ridge a mantle plume
rises and feeds unusually large volumes of magma to the surface. The result is
that the Ridge has risen above sea level and formed an island: Iceland.
Volcanoes abound in Iceland, there are over 30 active volcanoes within its borders and it
experiences a volcanic eruption on average once every 4 years. [4] Some of
these have global impacts such as the 2010 eruptions at Eyjafjallajokull which such
down airspace over much of western Europe causing a global disruption of air travel.
The Icelandic hotspot produces multiple kinds of magma.
Magma rises within the mantle due to differences in temperature and density.
Hotter magma tends to be lighter, and therefore rises. As it rises it cools, and as it cools it's consistency changes as it gradually thickens.
When it reaches the surface, if it thickens too much the gases within escape by shattering the magma in
violent explosive eruption. This type of magma caused the Eyjafjallajokull eruption.
It also causes the worlds other explosive eruptions like Mount Vesuvius,
Mount Saint Helens, Pinatubo, and Krakatoa.
If, however, the magma can rise quickly and not have as much time to cool down
then it surfaces as fluid similar to honey. Instead of exploding, the gases
propel the magma skyward in fountains of lava in an effusive eruption not at all unsimilar to geysers in
Yellowstone. Instead of blasting skyward as ash, the lava just runs along the ground
(mostly) harmlessly. It is magma like this that also produces the famous lava lakes
and fountains on the Big Island of Hawaii.
A "Tourist's Volcano"
It is this former type of magma that feeds the Reyjanes Volcanic Belt in the far southwestern corner of
Iceland. The Reykjanes Peninsula has a number of volcano complexes, where multiple small volcanic vents
are clustered instead of a single, large, mountain. Eruptions occur on the peninsula every few hundred
to a thousand years. The last one was in 1240.
Fagradalsfjall Volcano is one such complex.
Side bar: The Icelandic Language has it's own letters
and this Romanized version of the name doesn't sound the way it's spelled. The best I can describe it is:
fa-gra-dalch-fy-alch.
Fagradalsfjall originally
erupted under a thick glacier and formed a broad, flat topped mountain, with very steep sides. This
type of volcano is called a tuya volcano. In the early days of March 2021 the area began shaking
with an intense earthquake swarm. Over 40,000 earthquakes rattled Reykjanes, most of them too
small to be felt but several were enough to be felt across the peninsula and farther north in
Reykjavik. [5]
At 8:45 in the evening on the 19th of March 2021, after three days without earthquakes,
residents in Keflavik and Grindavik looked westward to see a red glow: magma broke the surface
on the southern slopes of Fargradalsfjall for the first time in over 6,000 years. When unrest
began in Reykjanes in 2019 it was expected that an eruption would occur at other nearby volcanoes
which were more active in recent history.
The 2021 eruption of Fagradalsfjall lasted for almost exactly 6 months – 183 days.
In that time over 150 million cubic feet of lava was erupted and the shape of Fagradalsfjall
had changed.[6] Moreso than any other eruption in Iceland’s history, this volcano became a
tourist attraction. It’s only a half hour drive from the island’s main airport and a short
(but steep) hike up the side of the mountain. Over 356,000 people saw this eruption, almost as many people who actually live
in Iceland.[7][8] It was a “tourist eruption”, and it was spectacular.
False Starts

August 2022, I am in the Black Hills of South Dakota about to go on a caving expedition to Wyoming when
I wake up one morning to find out that Fagradalsfjall is erupting again. This time I looked at plane
tickets (from Custer!). So, strike out the second chance. COVID and unemployment killed the first chance,
now poor timing killed the second one. I had mostly managed to forget about the previous eruptions
and any desire to plan to go see one had mostly been replaced by other realities of life.
Late 2022 was the release of The Fire Within: A Requiem for Maurice and Katia Krafft, a documentary
by Werner Herzog. This documentary released an hour of footage shot by the Kraffts that had been
scanned and remastered. While it lacked on details about the Kraffts themselves, it contained footage
that was just astounding. Coming in just another month was Fire of Love, a documentary by Sara Dosa
about the Kraffts – less so about their work and more so about them.
Fire of Love was the inflection point. I sat in the theater enthralled. I was amazed at how their
work and their lives were like what my partner and I were already doing with caves. Hope got the
volcano bug, too from this film. We saw it in theaters twice.
In November 2022 we almost had our chance. After 38 years of sleep, Mauna Loa began an eruption on the
big island of Hawaii. The eruption came a bit earlier than anticipated and I woke up one morning to
frantic notifications from volcano friends that a summit eruption of Mauna Loa had begun. Within a
few hours the eruption migrated to the flanks and a full-on classic Hawaiian eruption ensued. I had
plane tickets in two hours.
Then, it all fell apart. I could not responsibly get the time off work, so I’d be working on the
Big Island while trying to see the volcano. I also had to find a place to stay on the island.
The third was the location of the eruption – the closest viewpoints were miles away. While I was
finally more financially stable, I wasn’t exactly rich. I would have basically one chance to use my
“eruption pool” – did I really want to do it to fly to Hawaii for five days just to watch it from a
road 11 miles away? I cancelled the tickets.
There was another, broader, reason I backed off going to Mauna Loa. Hawaiian eruptions are deeply
sacred events to Native Hawaiians. They are not tourist events. Eruptions in Hawaii are not treated
like ones in Iceland, Japan, or Indonesia. I knew I’d be unhappy watching it from such a distance and
knew that being there and being unhappy about it would be offensive to local cultures and customs. The
desires, wishes, and beliefs of the locals must be respected – always. There will be a time to see
Madame Pele, but this would not be it.
I took the slide film I planned on taking to Mauna Loa and wrote on it in sharpie “For Lava Only”.
I threw it in the freezer so everytime I opened it I would see it and be reminded that I had a goal.
It would not be long before our next chance.
