Volcanoes on slow spreading centres appear to accumulate a lot of gas.
Eruptions on the mid arctic ridge about 3 years ago appear to have the equivalent in basalt of a plinian eruption of VEI 4.
Large basaltic eruprions of VEI 4 have occurred in iceland (Grimsvotn, Katla), in recent history.
No real surprises there.
Nice to see ancient evidence though.
Have a nice day: Ag
