How often does this occur, it happened at my hometown airport BUR. There was Rwy 07/25 and changed later to 08/26. Can someone tell me if this is caused by earthquakes and what other airports have this happened at? I think when BUR was built Rwy 7 was a 074 magnetic and is now 076. Thanks for all help! -Ryan

In short, the runway number is the magnetic direction of the runway divided by 10, then rounded to the nearest number. For example, if a runway points at 174 degrees magnetic, its number will be 17. The opposite end, being 180 degress off, will be 354, thus 35. The runway is 17/35.

The L and R mean left and right. This occurs where airports have parallel runways. So Manchester Airport in the Uk used to have a single 6/24 runway - it now has 6/24L and 6/24R as the new runway is almost complete.
