Newly-released security camera footage shows the moment last month's magnitude 6.8 quake shook Kumamoto General Hospital in Japan.

Four surgeries were under way at the time. Footage from a camera in an operating room where an abdominal surgery was being performed shows medical staff shielding the patient with their bodies as equipment swayed violently, and a nurse opening a door to secure an evacuation route.

According to the hospital, all four operations were successfully completed.

Kumamoto General Hospital resumed normal outpatient services on 5 August , after suspending them following the earthquake on 28 July.
