On Friday, August 21, the USGS Hawaiian Volcano Observatory (HVO) organized a helicopter LiDAR mission over flood-damaged areas in the Kaʻū district on the Island of Hawaiʻi following Hurricane Lala that affected the Hawaiian Islands the weekend of August 15. HVO normally uses LiDAR for assessing eruption-related landscape changes in Hawaii. Helicopter-based L

Flooding in the Ka‘ū district during Hurricane Lala over the weekend of August 15–16 appears to have activated hydrologic drainages that only carry water during the heaviest of rains.

The USGS Hawaiian Volcano Observatory helicopter lidar mission on Friday, August 21 provided near-vertical views down into narrow channels carved by streams on the southeast flank of Mauna Loa volcano. This photo shows Hionamoa Gulch just west of the town of Pāhala, clearly widened by flooding during Hurricane Lala the previous weekend.

This photograph shows the inside of the USGS Hawaiian Volcano Observatory (HVO) Multi-Gas site at Sulfur Cone high up on Mauna Loa's Southwest Rift Zone. Volcanic gas (Sulfur Dioxide, Hydrogen Sulfide, Carbon Dioxide, and Water vapor) concentrations are measured then telemetered back to HVO to be monitored and analyzed by HVO gas scientists.

During a morning overflight on December 9, 2022, Hawaiian Volcano Observatory geologists noted a reduced output of lava at fissure 3 on the Northeast Rift Zone of Mauna Loa. The lava fountain is much lower than yesterday and the lava in the channel is much lower than the levees. USGS video by M. Patrick.

The Northeast Rift Zone eruption of Mauna Loa continues with a major change overnight. The fissure 3 (F3) vent continues to erupt but the supply of lava appears to be much reduced this morning. Lava is overtopping channels near the vent with flows extending no farther than 2.5 mi (4 km) from the vent.
