Are you in or around Christchurch? Can you tell us what the feeling is like?
An earthquake measuring 7.1 on the Richter scale has struck around 30km west of Christchurch. The quake has caused minor injuries, structural damage and power outages. Several roads have suffered considerable damage, as have sewer lines around the city.
Civil Defence have asked people to assess their home or workplace for damage; look for and extinguish small fires if safe to do so; and not overflow the phone lines with non-emergency calls. They have also asked people to check on elderly neighbours. Police are warning residents to stay off roads and avoid the central city.
What has your experience of the earthquake been? Want to let family members know that you are safe?
