Preparations for this year's British and Irish Lions tour to New Zealand include contingency plans for an earthquake.
Numerous "what if" scenarios have been planned for, including back-up stadiums, should the test venues be damaged by a quake during the 10-match tour in June and July.
The welfare of the players has been at the forefront of the planning. The Lions have already switched hotels in Wellington from their original choice, because of safety concerns should an earthquake strike.
The revelations come just a day after New Zealand was hit by its latest earthquake near Christchurch, the city that will host the third tour match between the Lions and the Crusaders on June 10.
There have been 19 "large" earthquakes, above 6.0 magnitude, recorded since Christchurch was devastated in February 2011 by a quake that killed 185 people.
Lancaster Park, the famous Christchurch stadium where the Lions played their first test against the All Blacks on the 2005 tour, remains closed because of the damage.
