A collapse pond forms from the draining of pooled molten lava after a solid roof has formed over a lava pond. The weight of the unsupported roof may cause it to collapse. Pillars form where water rises from beneath a flow creating pillars of crystallized magma from within the deepening lava pools.

Lineated sheet flows form when molten lava flows out from underneath the edge of a solidified crust. The lineations are a result of the crust scraping against the surface of the moving molten lava.

Jumbled sheet flows form when the solidifying surface of the lava begins to fold under compression from the flow behind it.

Hackly sheet flows form when the solidifying surface of the fast moving lava experiences so much deformation that the solidified surface begins to break apart and piles up on itself. The edges are very rough and sharp.

Lobate flows form from low effusivity flows. (more..)

Pillow lavas (also called pillow basalts) result from the quenching - or very rapid cooling and crystallization - of the outer portion of a small extrusion of lava. Continued extrusion breaks through one pillow and forms a new adjacent pillow. Striations may occur from the lava being scraped by the rough edges at the point of fracture and extrusion.

Mitch Elend works to stitch images of the seafloor at Southern Hydrate Ridge together into a photo mosaic in real time. OOI scientists will use the final mosaic to plan the instrument layout for the cabled observatory component of the OOI. (photo by Allison Fundis)

The ROV ROPOS controls set up in a lab aboard the R/V Thompson. The ROV pilot, co-pilot, and a scientist sit in front of these monitors and controls during the dive. A ROPOS navigator and a team of scientists are also in the room logging and aiding in dive plans. (photo by Debbie Kelley)
