Rangitoto Island is a volcano. It blew up 500 years and at any time it could blow up again. Most likely in 500 years. However, it is more likely it has a lahsar and another volcanic eruption would blow up near this Island in the sea.
This could happen at any time even now. There has been some minor earthquakes in this area.
Hopefully if this happens we would all have warning and we would have to pack our essentials and leave as soon as possible.
Probably highly unlikely at the moment but one should always be prepared in case.
This is certainly true, we have some equipment and tremors are monitored. However, Auckland experiences tiny earthquakes all the time. Locals don’t notice it.
For such cataclysms like the eruption of a volcano is unforeseen. The important thing is to have warnings about it.
Thanks so much Elenka
