Less than 100km off the coast of Hawke's Bay is a deep-water trench that could be the site of a potential megathrust earthquake similar to the 2011 Japan earthquake, says seismologist Kevin Furlong.

Professor Furlong, of Pennsylvania State University, said the worst-case scenario for the East Coast was not yet known.
