Explosive eruption columns of ash rising from Halema‘uma‘u at 11:15 a.m. on May 18, 1924 (left) and at 11:05 a.m. on May 15, 2018 (right) look similar. Researchers are re-evaluating early assumptions about the role groundwater played in triggering these explosive eruptions at the summit of Kīlauea Volcano and are now looking at the build-up of gases from retreating magma as a likely trigger.

Volcano Watch: Did groundwater trigger explosive eruptions at Kīlauea?

An explosive eruption at Halema‘uma‘u in 1924 looks similar to the column of ash rising from Halema‘uma‘u in 2018.

After magma drained from Pu‘u ‘Ō‘ō on April 30, 2018, the crater was roughly 356 m (1168 ft) deep, with the upper part of the crater flared and the deeper part a narrower cylindrical shaft. Collapses on the crater walls have since enlarged sections of the crater and filled the deepest part with rockfall debris, creating a much different crater geometry—as shown in this comparison of models from May 11, 2018, and March 18, 2019. Today, the deepest portion of the crater is 286 m (938 ft).

Map of selected earthquakes beneath a portion of southeast Hawai`i from May 4, 2018 to March 14, 2019, showing principally aftershocks following May 4, 2018 M6.9 earthquake. Black dots indicate epicenters of 13,083 earthquakes located during this time interval; yellow stars show locations of the M6.9 earthquake and the March 13, 2019 M5.5 earthquake.

Volcano Watch: How is lava flow thickness measured and why does it matter?

During the first few years of Kīlauea Volcano’s Puʻu ʻŌʻō eruption, episodic high lava fountains produced multiple lava flows. After each event, Hawaiian Volcano Observatory scientists measured its thicknesses.

This ‘a‘ā flow erupted from fissure 8  on Kīlauea Volcano’s lower East Rift Zone on June 1, 2018, shows how the interior of a lava flow remains incandescently hot even though surface cooling forms a crust of solid rubble. Based on studies of lava flow cooling rates, it will take more than 130 days for a flow this thick (about 4.5 m, or 15 ft) to cool to a temperature of about 200 degrees Celsius (290 degrees Fahrenheit). USGS photo by A. Lerner.

Volcano Watch: How do lava flows cool and how long does it take?

Since the end of the 2018 lower East Rift Zone eruption questions have surfaced concerning how long it will take for the new lava flows to solidify.

A USGS pilot and Hawaiian Volcano Observatory gas geochemist prepare to conduct a test flight of an unmanned aerial system (UAS) on Kīlauea Volcano in November 2018. This UAS was outfitted with a prototype miniaturized multi-gas sensor for the detection of volcanic gases emitted by Kīlauea, including sulfur dioxide and carbon dioxide. USGS photo by Patricia Nadeau.

Volcano Watch: Low sulfur emissions mean a new focus on a different volcanic gas

Hydrogen sulfide (H2S) smells are still sometimes detected around the island, but it’s another gas emitted by Kīlauea that has become more important lately—carbon dioxide (CO2).
