This is a fly-over of the EM300 multibeam bathymetry data, featuring a section of the Mariana Arc volcanoes. The movie starts from the north looking southward. The first volcanoe that is flown over is Northwest Uracas. The black hole in the middle of the data set is the area of Farallon de Pajaros Island (formerly Uracas). The next volcano that is passed over is Makhahnas, then on to Ahyi. The final frame is a 2-d north-up image of the area. Movie thanks to support from Interactive Visualization Systems .
