Besides "felt earth tremor" reported by the public, the observatory also has basement facilities to monitor earthquakes happening around the world. The basement is seldomly open in order to minimise external interference. The latest episode of "Cool Met Stuff" will take you to visit this "basement of secrets". The video is now available on the "MyObservatory" mobile application and the Observatory's website for your viewing.
