Volcano Watch: Kilauea activity update for December 13, 2018

Thermal camera imagery of Route 130 show steam. Low rates of seismicity, deformation, and gas release have not changed significantly over the past week. Earthquakes continue to occur primarily at Kīlauea’s summit area and south flank.

Volcano Watch: We’re giving thanks for clean air, but what’s that new smell?

With these much lower emissions, many people have expressed surprise that a strong and slightly unfamiliar smell can be detected from Kīlauea during certain wind conditions.

Kīlauea Volcano's summit, as viewed from the southwest, shows the collapsed area of Halema‘uma‘u and the adjacent caldera floor. A section of Crater Rim Drive preserved on a down-dropped block is visible at the far right. Volcanic gases rising from magma stored beneath the summit continue to escape to the surface, as they have for as long as Kīlauea has existed, resulting in deposits of sulfur on the crater walls.

Volcano Watch: Kilauea activity update for November 1, 2018

A slight inflationary trend near and east of Puʻu ʻŌʻō suggests that magma may be refilling the middle East Rift Zone. Low seismicity and reduced gas emissions do not indicate that the magma is shallow, but HVO continues to closely monitor this area and will report any significant changes.
