Christchurch city is about 200 miles south of Wellington and Lower Hutt (where I live) and on the South Island. There have been no reports of any damage this far north or outside the Canterbury areas.
Although many felt the shaking here, I personally didn't and continued to sleep soundly throughout.
I believe that communications in the area and further south have been partially disrupted and suspect that club members in the area will perhaps have other things on their minds rather than being on-line.
Like other club members, I send my best wishes for everyone's safety and good health.
For those interested good coverage is available on
