  It would be nice if there was a way to manually enter location, since the location API on desktop is for me inaccurate by hundreds of miles.

  Closest one to me at the moment (in Pilsen, Czech Republic): Alban Hills [1]

  "Fun" facts:

  - it less than 30km from Rome, Italy

  - it emits enough CO2 that it occasionally kills livestock

  - last eruption is thought to be around 5000 BCE

  - a magma chamber is believed to be building up 5-6km below the surface

  This is awesome, but the closest volcano it brought up for me is a dormant one. It would be nice to see closest active volcano.

  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:)

  I'm glad of living in a country (Costa Rica) with several volcanos and a lot of them active, so indeed the app shows the closest!

  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.

  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.

  Devils Tower for much of the east cost US I'm guessing?

  Looks like volcanos are provided by a giant static JSON file. I'm curious, where/how was this data compiled?

  Regardless, very cool.

• by sdan on 10/19/19, 12:16 AM

  Apparently Mono Lake Vol Field is the closest to Silicon Valley

  No vulcano in Germany? Strange

• by chewxy on 10/19/19, 9:35 AM

  TIL there are volcanoes in Australia
