How many volcanoes can erupt at once?
In theory, there is no limit on the number of volcanoes that could erupt at once other than the number of active volcanoes themselves: while it is thus theoretically thinkable, that all 600 volcanoes (on land) known to have had eruptions during recorded history erupt at once, this is so unlikely that it can be excluded.
At any given time, about 10-20 volcanoes are erupting on average, and it could be imagined that this number sometimes peaks to about 30-50 erupting volcanoes (on land). Many more than that is very unlikely. Including submarine volcanoes, these figure probably have to be multiplied by a factor of at least two or three, but much less is know about the activity of submarine volcanoes.
In Earth's earlier history, there have been times when there were many more volcanoes active than today. Unless the Earth's present geodynamic system changes dramatically, of which there is no indication of happening in any foreseeable future, such levels of volcanic activity will never return.

Solar Eclipse & volcano tour
: A total solar eclipse will occur on 14 Dec 2020 and pass over southern Chile and Argentina. Chile's most active volcano Villarrica is located exactly on the center line where the eclipse will be best to observe.
We offer you the unique chance to combine the eclipse with a tour to one the world's most beautiful volcanic areas - the Lake District in Chile.
Photos from Armenia
: Armenia is a very photogenic country with a large variety of landscapes showing some very spectacular geology, century-old monasteries and castles, and much more.
Ethiopia and the Danakil
: Ethiopia is a very diverse and beautiful country. Thanks to our numerous expeditions to Erta Ale and Dallol
and beyond, we have an extensive collection of images showing the volcano's lava lake, the desert, the colorful hot springs of Dallol, the vast salt lakes, camel caravans and more.
