This study discusses findings from an interdisciplinary research expedition to the island of Anatahan (Commonwealth of the Northern Mariana Islands), 4months after its first recorded volcanic eruption. Deep ash completely obliterated any trace of reef communities off the northeastern shores of the island; however, reefs in other areas, although still blanketed with ash deposits, fared better. Mean fish biomass recorded around Anatahan after the eruption was 0.22kg100m−2, a value three times lower than at Sarigan, the closest neighbor island. Similarly, average percent cover of live coral (7.9%), crustose coralline red algal (7.7%), and macroalgal (14.3%) populations was 2.3, 1.4, and 3.0times lower than at Sarigan, respectively.
