A380 wake turbulence during cruise flight.We were at FL260 on the ANJLL arrival into LAX when we encountered moderate wake turbulence. The aircraft rolled left 15 degrees bank and then back to the right 15 degrees bank. The autopilot remained on. ATC was notified and acknowledged we were 10 miles behind an A380 that had descended in front of us. We offset our course upwind and slowed the aircraft for additional spacing. No passengers or crewmembers were hurt during the event. After landing; ATC was called by phone and we spoke with a supervisor; [who] said [they] would investigate how the events occurred. Dispatch was also notified. Suggesting a study be performed to provide ATC and crews on proper minimum spacing behind an A380.
Encountered wake turbulence 10 miles behind an A380. Aircraft bumped and rolled 15 degrees left. Then bumped and rolled 15 degrees right while on autopilot. Autopilot did not disconnect. No injuries with passengers or crew. Contacted ATC; slowed; and offset upwind. A380 was brought in [near] us and descended in front of us. Until the turbulence; we were not aware an A380 was near us. After landing contacted ATC by phone; called Dispatch and called flight safety. Suggestions: Provide more spacing behind A380 aircraft. Notify other aircraft when following or crossing behind an A380.
