Christchurch gets a 'Shaking All Over' again

On the social media feeds -- just 8 days short of the 5th anniversary of the earthquake which killed 185  people, Christchurch has experienced a magnitude 5.8 earthquake at 1:13 pm local time, said to have been at a depth of 15 km and centered 10 km east of the city.

Those figures aren't as bad as 5 years ago, and anything that could collapse would have been removed or strengthened since, but it's not going to do psychological health any good.
