Details of the discovery of the submarine landslide and tsunami were published this week in Marine Geology.

A sudden release of methane hydrate, for example, as a result of a submarine landslide (e.g., Bryn et al, 2005), might allow methane to be released to the atmosphere, but the amounts released from an individual landslide is expected to be small (RealClimate).
