Feeling the earth shake

In the space of five days between the 17th and the 21st of July, we have experienced 3 earthquakes. Nothing too major, but because we are in the van, we feel it a lot stronger through the rocking of the suspension. When in Auckland we experienced a quake that shook the house, now that was scary. These have just been minor, and we're alright, hopefully though they don't develop into larger ones.
