Closest one to me at the moment (in Pilsen, Czech Republic): Alban Hills [1]<p>"Fun" facts:<p>- it less than 30km from Rome, Italy<p>- it emits enough CO2 that it occasionally kills livestock<p>- last eruption is thought to be around 5000 BCE<p>- a magma chamber is believed to be building up 5-6km below the surface<p>[1] <a href="https://en.wikipedia.org/wiki/Alban_Hills" rel="nofollow">https://en.wikipedia.org/wiki/Alban_Hills</a>
Huh. It's just a black screen with a red "Calculating..." in the upper left corner and a Bitcoin wallet in the upper right. Nothing else. Safari 12.1.2
Closest to me (in Austin, TX) is the massive Carrizozo Lava Flow in NM. I've actually been there via the Valley of Fires State Park. It's an amazing place, and seems to be usually empty- definitely worth a visit if you're in the area!
Currently in a country with some excellent volcanoes: Ethiopia. Sadly this site isn't loading - I assume it is too big a download (not great internet up here in the mountains). A lightweight version would be great:)
ATM this returns an incorrect answer for me (at Strasbourg, yet returning Dôme volcano circus in the center of France, 645km) as the closest volcano is actually the Nideck, a 250'000'000 year old volcano, a mere 35km from here.<p>(Photos, with geological layout at the end)<p><a href="http://www.passion-escalade-et-montagne.com/2018/04/escapade-en-terre-volcanique-nideck-m-et-hirschfels-545m-29/04/2018.html" rel="nofollow">http://www.passion-escalade-et-montagne.com/2018/04/escapade...</a><p><a href="http://www.randoalsacevosges.com/2015/03/le-volcan-du-nideck.html" rel="nofollow">http://www.randoalsacevosges.com/2015/03/le-volcan-du-nideck...</a>
Thank you for the feedback! I am going to collate the inaccuracies and update the volcano database. I am also going to try to fix the errors a few of you have experienced.
