View of the recently cleared Boiling Pots on the Wailuku River in Hilo. The pots, each about 15 m (50 ft) in diameter, are eroded into a 10,000 year old Mauna Loa lava flow. When the water is low, the river does not flow over some of the pot rims but it continues to flow through them. USGS photo.

HVO geologists visited the lower East Rift Zone lava flow field this past week to make measurements and observations, to better understand and reconstruct the dynamics of the Fissure 8 lava flow. This photo shows the channel wall in the braided channel region of the flow.

Rain on mountain snow caused the streamflow in Dinwoody Creek to more than quintuple in 24 hours resulting in some of the highest flows recorded in the 52 years of data collection at the site. Real-time and historical data at: http://ow.ly/DLpH50An6q6

This is an animation showing the changing conditions of USGS streamgages from April 1, 2020 to June 30, 2020. The conditions shown range from the driest condition seen at a gage (red open circles) to the wettest (blue closed circles). There is also a purple ring added to indicate gages that are flooding.

Mineral elements provide the color in fireworks. Barium produces bright greens; strontium yields deep reds; copper produces blues; and sodium yields yellow. Other colors can be made by mixing elements: strontium and sodium produce brilliant orange; titanium, zirconium, and magnesium alloys make silvery white; copper and strontium make lavender.

Geologists from Montana State University study an outcrop of diorite (a silicic igneous rock that cooled slowly beneath the ground). An outcrop of this size is important because it is easier to see any structural relations along with rock composition.
