Sand volcano's erupting



 There was a 7.1 Richter earthquake in Canterbury early hours of Saturday morning. It was pretty amazing. I stumbled out of bed in a daze and held onto the book cases to stop them falling over. For which later I got royally told off by my better half.

Luckily there was no loss of life, owing to the building code in place, but I think this natural disaster will turn into a social disaster for many people in the months to come.

In many parts of the city there was soil liquefaction and the curious phenomena of sand volcano's popping up everywhere with the roar of gushing water. I found these sand volcanoes (also known as a sand boil) fascinating and quite beautiful. The strange thing was that the mouth was often very clear of sand or silt of any kind as if they had been washed.
