Today we had a special visitor. Julian Atkins came to talk to us about his job as the National Fingerprint Officer at Porirua Police College.
After the devastating Indian Ocean tsunami on Boxing Day 2004, Julian was part of an international team who helped identify victims of the tragedy.
He told us about how tsunamis are caused, what happens to the the tide before a tsunami hits and how our fingerprints are so unique. We talked about what we can do to be safe if a tsunami ever hit.
It was really interesting, and helped us with our understanding of our BIG QUESTION - What causes natural disasters and how we can be safe if one happens.
