Here's an update from Heather, our Senior Vet on site:

Buildings shaking and C1 building (office and accommodation) shook a lot and is dodgy. Accommodation is unsafe and there are cracks in the ceiling. Ground moving and building swaying, tiles missing off roofs, concrete has fallen down a big hole in roof of bear kitchen, but people and bears are OK. 

House two and three you wouldn't know a thing had happened. Jasper and team lay out sunbathing as if nothing had happened. All other bears bolted back into their dens, panicking and jostling to get back through the slides of their den doors - but OK now. We're still getting tremors and aftershocks.

Heather says all staff have been moved from their regular accommodation to the old and new hospitals.
