Into the Air: a Sky Filled with Ash, Gas, and Glass

Growing up in the mountains of Colorado I appreciate fresh, clean air. As I inhale, I greatly enjoy the crisp aromic air of Santorini.  In general we take for granted the air we breathe in, we know that it’s oxygen, nitrogen with a little too much carbon dioxide sometimes, and some places are more humid than others. Otherwise most places we go we don’t have to worry about blocks of hot volcanic rock the size of small cars zooming through the air or breathing in high amounts of methane, carbon dioxide, liquid glass, and hot ash.  During the cataclysmic Minoan eruption in 1613±13 BC the air here resembled the latter. Almost instantaneously the air went from out typical Santorini weather to being suffused with acidic gases, ash, pumice, and various rocks filling the sky above. As we went to various outcrops on the island we saw evidence of the massive amount of material that filled the sky’s that day 3600 years ago.

Moving Megatons: The Excavational Eruptions of Calderas

I’ve just learned the full story of the Minoan eruption. In my mind, I’m imagining 60 cubic kilometers of earth. This is about the size of a block of the Los Angeles basin, by volume; a massive amount of land. I can see all this land being ejected by the volcano miles into the sky, over a span of 24 hours. Such is the case of Santorini’s last caldera forming eruption.  Continue reading “Moving Megatons: The Excavational Eruptions of Calderas”

Rocky Heights: Sacred Land and Geology meet in Athens

I step off the marble curb of my hostel into the quiet streets of Plaka in Athens, Greece, and I am alone for a just a moment. The same grey and black cobblestone streets that were alive with the energy of tourists and vendors only hours before are now quiet. Once bright pastel buildings have been dulled by the sun’s rays. Their shutters hang askew, and clothes lines overhang the narrow streets like banners stretched between buildings. Next door, an old man sweeps the streets outside the Taverna with its red and white checkered table cloths. Continue reading “Rocky Heights: Sacred Land and Geology meet in Athens”
