When Rotorua resident Susan Gedye was awoken at 2am by “a lot of shaking and jolting” she thought it was an earthquake.

But then she headed downstairs at her suburban home and saw that her kitchen windows had steamed up and a large mud geyser had appeared in her garden.
...
The volcanic activity resulted in a large crater on her front lawn with the thermal pool throwing boiling mud 10m into the air.

Authorities also found a sinkhole under Gedye’s kitchen meaning her family, including two children, have been forced to move out.
