8:00 am on 5 March 2011

About 80% of the silt left by liquefaction in the earthquake has been cleared.

Civil Defence says about 220,000 tonnes of silt have been removed so far - about 50,000 tonnes on Thursday alone.

In the earlier quake on 4 September, only 35,000 tonnes of silt had to be removed.
