What exactly is a 'volnado'?
A 'volnado' is a vortex of ash, volcanic gases, and molten rock that forms during eruptions. It looks like a swirling whirlpool of debris and is often seen during explosive volcanic activity. These whirlwinds are a known phenomenon during eruptions and are caused by the intense heat and turbulence within the volcano's eruptive vents.

How active is Kilauea right now?
Kilauea is currently in its 32nd eruptive episode since December, with ongoing activity that includes lava fountains, ash clouds, and the formation of 'volnados.' The eruption remains contained within the summit crater, and scientists monitor it closely through livestreams and cameras to track its behavior.

Does the current eruption pose a threat to nearby communities?
At present, the eruption is contained within the volcano's summit crater, and there is no immediate threat to nearby communities. The USGS and other agencies continue to monitor the situation, and safety measures are in place to protect residents and visitors. The visual phenomena like 'volnados' are spectacular but do not increase the danger level.

Why does Kilauea keep erupting?
Kilauea is one of the world's most active volcanoes due to its geological setting. Magma from deep within the Earth continuously rises to the surface, leading to frequent eruptions. Its current activity is part of a series of repeated episodes where magma follows the same pathways to the surface, reshaping the landscape over time.

How do scientists monitor eruptions like Kilauea’s?
Scientists use a combination of livestreams, cameras, seismic sensors, and gas measurements to monitor Kilauea’s activity. These tools help track eruptions in real-time, assess potential hazards, and provide early warnings if the situation changes. This close monitoring allows for timely updates and safety advisories for the public.
