    I've not heard of green ash before. Is it mineral or perhaps algae/plant matter?

    Ruapehu had a brief earthquake swarm last week under the volcano. The crater lake at the volcano’s summit also experienced warming. The swarm was a little out of the ordinary for Ruapehu, but the unrest seems to have quickly subsided and the temperature of the crater lake has also declined. According to the new article, the lake has warmed over 15ºC over the last few weeks, peaking at 42ºC.

    haven't heard of the green ash either.
    I know the hot pools within the crater are quite colourful with various algae, but I wouldn't have thought it would have been enough to produce
    such a noticeable colour change in the surface of the crater walls if this water was then ejected out of the crater

    I might send GNS an email and see if they have an explanation :smile:
