An Hawaiian Volcano Observatory geologist monitoring K?lauea ?volcano is erupting. Hawaii, USA. With the summit eruption continuing through the night, HVO scientists monitor the eruption for changes in activity and volcanic hazards. High levels of volcanic gases are the primary hazard of concern, as this hazard can have far-reaching?effects down-wind. Credit: D.

An Hawaiian Volcano Observatory geologist shields his face from intense heat as he dips a rock hammer into an active p?hoehoe toe. After scooping out the lava it is placed in the water to quench it. HVO routinely collects lava samples for chemical analysis, which can give insight into changes in the magmatic system.

Lava Sampling Ñ Geologists at the Hawaiian Volcano Observatory (HVO) take lava samples as close to a vent as possible. Once the sample is scooped from the p?hoehoe lobe, it is quenched in water to stop the growth of any crystals and to preserve the composition of the liquid lava. Once cooled, the sample is sent first to UH Hilo for basic analysis before being sent for fuller analysis by a lab on the mainland. This data is used, with HVO's geophysical monitoring data, as another way to assess any changes that may be occurring within K?lauea volcano.
