No, this is not a picture of our building site but rather the remnants of a lahar that sent 1.4 million cubic metres of water, mud and volcanic material out of Mount Ruahpehu yesterday. This event has been predicted for many years with civil defence systems on stand by. By al accounts it was a spectacular event although now there is plenty of clearing up to do.
