Hawaiian Volcano Observatory — after the next projected lava fountaining episode of the ongoing episodic eruption at the summit, which will be Episode 44, sometime from April 6-14 — will change how it applies alert level and aviation color code to better convey hazards between and during eruptive episodes at Kīlauea summit.

Hawaii’s most active and popular volcano, Kilauea, is preparing to put on a show as geologists forecast the volcano’s 44th eruption in the coming days. The United States Geological Survey said that precursory eruption activity is occurring as the active volcano prepares to erupt – one of Earth’s most captivating natural spectacles.

No other puʻus exist on the caldera rim, but geologic deposits of tephra fall mapped in Kīlauea’s summit region indicate that high lava fountains erupted within Kaluapele around the years 1500, 1650, and in the first two decades of the 1800s.
