I was about to make a post about the volcanic ash problem, but then Christchurch was hit by a series of large aftershocks, the largest at 2:20pm measuring magnitude 6.0, and 8 on the Mercalli scale which measures the intensity of the shaking.
Once again, social media like Twitter and Facebook have been providing rapid reports of what's going on, leaving the news media to play catch-up. The Twitter feed on the article on stuff.co.nz is pretty interesting reading.
First hand reports of the effects of the quakes can be quite vital - and a great way to know that your friends are okay enough to be typing and texting. Sometimes inaccurate information gets forwarded around, so it generally pays to verify that before taking it as gospel.
So far there are reports of more liquefaction, power, phone, & water outages. A few buildings have collapsed, but they were, for the most part, red stickered after the previous quakes. The Red Zone has been expanded back out again, as the already unstable buildings have been further destabilised.
Here in Porirua we're making sure that our staff are ready & able to return to Christchurch to lend a hand like we did after the February quake, or help locally with any regional response.
