“Let’s just hope it doesn’t explode,” was the reaction of a Rotorua resident who says her house shook when a “mud pot” burst into life over the weekend.
Rotorua Lakes Council cordoned off an area of Meade St on Saturday following some renewed existing geothermal activity there, advising the public to stay away as a precaution.
In a statement on Monday, the council said it was “keeping a close watch” on the geothermal activity.
“A resident mentioned that there’s been more rumbling, so we’re regularly checking the heat and gas emissions near the site to be safe.
“As an added precaution, we’ve made adjustments to the fencing around the site and reminded everyone to avoid that area.”
She said she was asleep while the activity was at its peak. But shortly afterwards, she discovered her car covered in mud and “splatters of mud on the house.
“I keep thinking something else is going to happen [from the] little jolts because we are so close.”
Emery said she did not want the “ground to swallow us up”.
If the geothermal activity worsened, Emery said she and her children could stay with family.
“Let’s just hope it doesn’t explode,” she said.
Local Rotorua resident Genna Emery's car was covered in splatters of mud after geothermal activity yesterday morning.
GNS Science volcanologist Brad Scott said the geothermal activity was named a “mud pot” and the activity was due to the reactivation of an existing surface feature.
“This feature has been active before about four years ago. It was active for several months at that time. It was also active four to five years before then.”
He said the Rotorua geothermal system was “active” and “from time to time, the level of activity in a feature will change”.
Scott said the activity from the mud pot was controlled by the amount of steam coming from beneath it and local groundwater.
“There has been an increase in steam flow from depth that is mixing with the local groundwater to soften the clays on the pool and reform a pool of hydrothermal muds.”
“Glad I didn’t have any washing on the line, brother,” he told the Rotorua Daily Post on Saturday.
“I got up at 7am - I noticed the steam about 7.30am. Everything in our house was shaking. I just finished doing some baking, and the milk inside the fridge and everything was moving,” Witika said.

“This morning it was misty mud, like water vapour, then before lunch, it started shooting out mud.”
Witika said he could also smell it in the house.
“Me and my partner were just talking about it - we will probably take the kids somewhere else. I don’t know if the fumes are bad, but we don’t want to be around here breathing in this air.
