No warning for liquid to gas eruptions. That's why there have just been lots of deaths at White island.

In Auckland we'd get rumblings as magma floats upwards with not much gas. That sort of eruption is fun to watch from half a kilometre away.

Taupo is a monster column of pumice squashed into liquid.

The mechanism of eruption is pressure relief from the top when the column of CO2 water hydrocarbons turns from liquid phase to gas.

Unlike short period volcanoes and geysers like old faithful and white island, the 2000 year period volcanoes erupt when fully loaded from subduction and then the downward pressure is relieved by low groundwater and lake level and when moon and sun align for super low tide.

Superheated water will boil squirting upward and send dirt into the air the dirt will splash down pushing water out of the lake. Meanwhile more liquid will turn to gas because the pressure has reduced sending more dirt up. That process continues and keeps accelerating, then hydrocarbons reach ignition temperature meaning in air there's also explosion which sends 1000 cubic kilometres into the sky.

The warning would be minutes rather than days. Maybe an hour of initial geysering.

When pressure is off a superheated liquid they turn to gas really fast.

A 200 kilometre deep column of hot stuff and as big around as Taupo is a lot of exploding pumice to fire into the sky.
