This is going to be a long post showing three inter-related data types useful for monitoring the world volcano situation. I've already displayed the first one back in April when I pointed to Kilauea's deformation chart to say an eruption was imminent.

This is the chart that will likely first bring forward the data to interpret as far as imminence of Mauna Loa eruption. After inflationary pressure eased after the "gap up" to start the year (maybe yearly instrumentation recalibration?? or maybe not) now it's definitely starting to become more restive. (similar to June-July last year). volcanoes.usgs.gov
Increased earthquake activity near around its flanks and summit will intensify prior to a deformation "breakout".



Might as well throw in the recent shot of Ambae in Vanuatu. This volcano has already rendered its home as an uninhabitable home for humans during the last year. (As you may recall: May 3, 2018 - The Pacific nation of Vanuatu is preparing to permanently evacuate the entire population of one of its islands as thick ash spewing from a volcano kills crops, dirties water supplies and fouls the air. cnbc.com


THEN, there's the lists of "Earthquakes near Volcanoes"

volcanodiscovery.com

I randomly chose Katla in Iceland (well not so randomly, it's a really dangerous one and was on the list)
volcanodiscovery.com



You can see it had a jump in EQ activity on May 21.
Going to the SO2 map for that day there is seen a slight detection also on that day. (as compared to other days)





This way you will be able to check a volcano that is getting shaken up for anything more coincidentally eruptive.

The Lo' ihi Seamount has calmed from recent activity.




But quakes deep under Pahala continue

Note the depth of the highlighted quake. They are all down there.


This diagram shows the Kilauea summit and Southeast Rift Zone, down to the reservoir but does not include the Mauna Loa conduit shown in the next diagram. Leilani Estates and other inhabited areas are,and/or were further to the right along there.
Pahala is below the Southwest Rift Zone.


Lo'ihi is likely also fed from the same deep reservoir as the summit reservoirs of Mauna Loa and Kilauea. That deep reservoir is mostly about 20 to 30 miles beneath Pahala. Deep Pahala quakes also occurred in swarms during the Kilauea eruption. Temperatures of the lava at "Fissure 8" were described as "mantle temperatures" by the USGS. Hotter than just that from the drained summit lake.
When the deep reservoir gets busy, there's more than likely an eruption around somewhere. Lo'ihi would be my guess.

"The research offers the first plausible model that can explain both the opposing long-term eruptive patterns at Mauna Loa and Kilauea—when one is active the other is quiet—as well as the episode in 2003-2007 when GPS records showed that each bulged notably due to the pressure of rising magma. The study was conducted by scientists at Rice University, the University of Hawaii, the U.S. Geological Survey (USGS) and the Carnegie Institution of Washington."
"We know both volcanoes are fed by the same hot spot, and over the past decade we've observed simultaneous inflation, which we interpret to be the consequence of increased pressure of the magma source that feeds them," said lead author Helge Gonnermann, assistant professor of Earth science at Rice University. "We also know there are subtle chemical differences in the lava that each erupts, which means each has its own plumbing that draws magma from different locations of this deep source. bigislandnow.com
