Bright aquamarine water indicates high concentrations of volcanic material. Immediately above the vent is a patch of brown water that can resemble a turbulent hot tub when the eruption is strongest. Video of the eruption shows the activity in more detail. This image was acquired by the Advanced Land Imager (ALI) aboard the Earth Observing-1 (EO-1) satellite. The eruption is just off the southern coast of El Hierro, the youngest of the Canary Islands. El Hierro is about 460 kilometers (290 miles) west of the coast of Morocco and Western Sahara. According to El Hierro Digital measurements of the sea floor by the Instituto Oceanográfico Español sh...
