Unmanned Aircraft Systems (drone) enabled HVO to obtain crucial data that would otherwise have been difficult or impossible to obtain during the 2018 eruption.

USGS HVO will conduct flights to assess volcanic activity and maintain instrumentation, and to survey for ungulate control and maintenance purposes.

The USGS Hawaiian Volcano Observatory has been named as a finalist for a 2019 Samuel J. Heyman Service to America Medals (Sammies) award.

There were no active lava flows on the pali, coastal plain, or entering the ocean.
