As it stands we seem destined to see it happen in plus/minus 50 years. But the known, unpredictably-timed potential for a new volcano or a seismic rift can pre-empt that scenario by decades.

However, the longer such an incident delays, the more severe an eruption could be as the gas inventory builds.
