Lava enters the ocean, creating a steam cloud with spatter.

Limu o Pele, each piece is about two inches across. Limu o Pele forms when lava enters the ocean, and is stretched paper-thin to form large sheets of volcanic glass, which are quickly shattered by wind and rain. Photo by Ken Hon.

GEOL 111 Field Trip

Photos below are from the 20th October 2010 field trip of Steve Lundblad. Students practiced taking temperatures of lava flows that were a few days old, using a thermocouple. The group then hiked uphill to active pahoehoe, measured the temperature with a radiometer, and demonstrated viscosity with a rock hammer.

Students read temperatures
Photos above shows two different readings (degrees F) of two cooling lava flows. Note the red glow in the crack on the right.
A student measures the temperature of the lava using a radiometer; note the zoomed-in infrared image on the screen.
Lundblad scoop
Above photo, Professor Lundblad breaks open the crust of a pahoehoe flow to demonstrate viscosity and rate of cooling.

GEOL 470 Field Trip

John sets thermocouple wires
Above, a geology student has carefully positioned thermocouple wires (lower right of photo) as a new breakout of lava occurs. Data is being collected on the rate of cooling of a new lava flow over time.
Meanwhile, another geology student measures inflation of the flow field using a Total Field Station.
