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.

Waves of orange, glowing lava and smoky ash belched and sputtered Monday from the world’s largest active volcano in its first eruption in 38 years, and officials told people living on Hawaii’s Big Island to be ready in the event of a worst-case scenario.

Precursory activity at Kīlauea on Hawaiʻi Island has paused, but an episodic fountaining eruption is forecast to occur sometime between today and April 15. Fountaining episodes typically last less than 12 hours but ash can remain in the air longer depending on wind and weather.

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.

Dubbed the Kikai caldera, this mostly-underwater caldera located south of Japan’s Ryuku Islands last erupted 7,300 years ago, marking the largest volcanic eruption in the current geological epoch, the Holocene.

A recent study reveals that the Poás volcano has changed its eruption pattern, redefining the global ash-related risk map.
