Sunday will mark one year since the Hunga Tonga-Hunga Ha'apai eruption.
Marco Brenna, a volcanologist at Otago University, says the volcano is still technically active, but it’s very minor.
“The volcano is still brewing away, although deep beneath the waves, but a lot of that energy that had been stored has been lost, so it’s unlikely that the volcano will produce such a large eruption again in the next few years, decades even.”
The most recent eruption followed previous patterns to begin with, says Brenna.
