Hawaiʻi photographer Ryan Ikeuchi just melted our faces off with this retrospective IG post of the time that both Kīlauea & Mauna Loa were erupting at Hawai'i Volcanoes National Park, 2 years ago...AND the full moon!

This is a screenshot from IG. Find his account here: https://www.instagram.com/ryan_ikeuchi/

"Happy no one lost their life or property, hassa sad because no more new rock or pretty lava."

Response:
"Some of the lava fountains were quite spectacular. Sharing with you, a short video from Dec 1, 2022 of Mauna Loa's fissure 3."

"This idea does remain robust because the two volcanoes can still "feel" one another through stress effects. They don't have to be directly connected for this to happen. An example model of this process was published in 2012: nature.com/articles/ngeo1….https://www.nature.com/articles/ngeo1612"

Coupling at Mauna Loa and Kīlauea by stress transfer in an asthenospheric melt layer - Nature Geoscience

Over the past decade, Kīlauea and Mauna Loa—adjacent volcanoes in Hawai‘i—have inflated and deflated in tandem, yet their shallow volcanic plumbing systems are separate. Numerical modelling of the volcanoes shows that dynamic stress transfer by asthenospheric pore pressure is a viable mechanism for volcano coupling in Hawai‘i.

Intershield geochemical differences among Hawaiian volcanoes: implications for source compositions, melting process and magma ascent paths | Philosophical Transactions of the Royal Society of London. Series A: Physical and Engineering Sciences

As Hawaiian volcanoes develop, their lavas systematically change in composition and isotopic ratios of Sr, Nd and Pb. These trends provide important constraints for understanding plume-related volcanism as a volcano migrates away from the hotspot. There ...

Answer:
"There are geochemical trends that separate Hawaiian volcanoes - the Kea and Loa trends. Mauna Loa is on the Loa trend and Kilauea is on the Kea trend. Isotopic geochemical signals provide evidence for a bilateral hotspot plume that feeds the two trends."

Question:
"Would it be possible to provide more detail on the geochemistry of the two vents & why these differences indicate a magmatic source from different parts of the mantle- As opposed to fractions crystallisation
Given the timing of eruption of the 2 vents is the theory still robust"

Question:
"Are Mauna Loa and Kilauea’s plumbing systems completely disconnected or are they joined at depth?"

Answer:
"The compositions they erupt have subtle differences that indicate they come from different places in the mantle. So while they are part of the same overall hotspot system, they do not appear to be physically joined."

"Is this a coincidence? Maybe. Maybe not. The volcanoes are not directly connected, but might "feel" one another via stress effects. Mauna Loa's eruption could have allowed Kīlauea to "relax." That said, Kīlauea's eruption was already pretty tenuous, occurring at very low rates."

"Yes, you saw it right -- alert levels for BOTH Mauna Loa and Kīlauea were lowered this morning. Neither volcano is erupting right now, and gas emissions are at near-background levels, although HVO volcanologists remain vigilant for changes that might indicate renewed activity."
