Cameras installed by the U.S. Geological Survey captured a small whirlwind forming over Hawaii's Kilauea volcano on Monday, June 1 [1].
The event highlights the volatile atmospheric conditions created by active volcanic craters, where extreme heat and shifting winds can produce rare meteorological phenomena.
This specific whirlwind is known as a "Tephra Devil" [2]. These occur during eruptive activity when hot air and volcanic debris swirl together over the crater [2]. The footage provided by the USGS shows the whirlwind rotating rapidly within the volcanic environment, creating a fiery, tornado-like appearance [2].
Kilauea has remained highly active throughout the year. Reports on the frequency of these events vary, with some records indicating the event occurred during the volcano's 47th eruptive episode [2]. Other reports describe the activity as the 46th eruption of 2026 [3].
Such phenomena are typical of the intense thermal gradients found at active vents. As the volcano releases heat, the air above the crater warms and rises rapidly, which can trigger the rotation of ash and gas. The USGS monitors these events to better understand the dynamics of the eruption, and the behavior of the volcanic plume.
Because the Kilauea volcano is one of the most active in the U.S., the continuous camera surveillance allows scientists to document these brief events in real time. The Tephra Devil is a visual manifestation of the energy being released from the earth's interior, a process that continues to reshape the Hawaiian landscape.

The appearance of a Tephra Devil underscores the complex interaction between geothermal heat and the local atmosphere. While visually striking, these whirlwinds are indicators of the high energy levels present during an eruptive cycle. The discrepancy in eruption counts—between 46 and 47 episodes—reflects the difficulty in defining the start and end of individual eruptive pulses in a volcano that is nearly constantly active.
