10,000 years ago
Koko Crater last erupted 10,000 years ago. It does not erupt lava because cold seawater entered its volcanic vent. It is called a tuff cone because it only erupts ash and tuff (fine ash).
Mount Etna last erupted in January, 2014. It was a minor eruption that closed the airport and created a new crater on the southeastern side of the volcano.
A volcanic crater does not have a function, per se. Rather, it is formed as a natural after-effect of volcanic eruptions. When volcanoes explosively erupt, molten rock is thrown clear of the main vent, where it can cool and harden; gradually, this builds the elevation of rock surrounding the vent, leaving a lower pool in the center of the volcano, and developing a crater (or bowl) shape.
No. Copernicus crater is an impact crater.

Nobody knows because volcanoes just erupt when the lava builds up and is forced up the main vent and out of the crater!
get to the crater of a volcano that is going to erupt in just minutes then you will find your answer.
Oahu contains at least 10 different and distinct volcanoes. Diamond Head is well known by Honolulu visitors and some people even recognize the National Cemetery of the Pacific or the Punchbowl as a volcanic crater. A drive around the Island is required to spot some of the others. Koko Head and Koko Crater are easily defined from the air as is Salt Lake.
A super volcano is a huge sized volcano that can erupt, the eruption will create crater sized holes around the eruption.
There is an increase in seismic activity (mini-quakes, vibrations, rumblings), and more smoke and lava spray showing above the crater.
Volcanic pipes that erupt diamonds to the earth's surface are uncommon in the United States. The Crater of Diamonds State Park in Arkansas is an exception.
If you mean 'how does lava release itself from the volcano', it erupts through the volcano's crater. But if you mean 'how does lava erupt from the volcano', then sorry, I have no answers to that.
KOKO - AM - was created in 1954.
Mount Etna last erupted in January, 2014. It was a minor eruption that closed the airport and created a new crater on the southeastern side of the volcano.
