Blast from septic tank

A SEPTIC tank was at the centre of an explosion that ripped through the Chinese megaport of Ningbo at the weekend, killing at least two people and injuring 20 more.

The blast, which erupted in a vacant lot, was so powerful it was heard several kilometres away, toppling nearby disused buildings, shattering windows and mangling cars.

Two people were missing. Four people were severely injured and 15 others had minor wounds.
