Mauna Loa Concerns

Like most armchair volcanologists on this island I have been monitoring Mauna Loa more closely lately. The deformation graphs in particular have been? Interesting. I have even gone so far as predicting that we will not get through the year without a Mauna Loa eruption.

The area of concern has been the western rift zone, exhibiting steady and shallow seismic activity for the last several years. More concerning is the rate of inflation shown in the GPS data, This seems to have doubled in rate around last October.

Then comes today.

An intense seismic swarm is currently occurring beneath the NW flank. Still fairly deep. a few kilometers below the surface, but getting shallower. Magma is definitely moving, a sizable mass moving upwards and emplacing itself higher in the volcano.

This may come to nothing in the near term. Like many seismic swarms it may stop. Just part of the process towards a future eruption some years from now, or never. Or we may be seeing the first step in a new eruption. I will hold to my prediction of an eruption sometime in 2021.

Sit back and watch.

Mauna Road

Two missions up into the saddle this week to go comet watching. Comet C/2020 F3 NEOWISE is rising in the northeast, blocked from view at home by the mauna, need to drive up to where I can see it.

With the comet as an excuse to get out well before dawn I may as well add a few secondary missions to the plan…

Make sure the drone batteries are charged for a few flights to photograph the saddle scenery at sunrise. The lava fields are spectacular at sunrise, one of my favorite places on the island.

The next mission is to photograph pueo along old Saddle Road. I tried two times, both times not a single bird to be seen. Where are the owls?

In any case a couple memorable trips into the dawn.

A Bright Comet in the Dawn

We have a bright comet in the dawn sky for a few days. Comet C/2020 F3 NEOWISE has brightened rapidly over the past few weeks, now about 1st magnitude it can just be seen against the glow of dawn.

I took along Hodepodge to serve as a tracking mount for the TV-76mm scope and a couple cameras to do some comet shooting. The Canon 6D would go with the small ‘scope, the EOS-M5 with a tripod for wide angle shots.

Driving up Waikoloa road I was troubled by a bank of clouds in the Waimea saddle, thus I elected to head for the Humuʻula saddle instead. I ended up in the lava fields along the Mauna Loa access road. The view was perfect, and I had just enough time to get the mount and camera setup as the comet rose.

Chasing Fogbows

I have been flying a lot in the Saddle over the last few months. It helps that I can simply leave for work early, stop off and blow through some drone batteries, before heading on to Hale Pohaku where I meet the rest of the crew for a day on the summit. The process can be reversed on the way back down the mauna in the evening after work.

On these short days late in the year this means flying right at dawn and sunset, creating very dramatic light. The rich colors are simply great for photography of this beautiful area of lava flows and cinder cones.

What makes the are even more spectacular is the cloud layer. As you drive up the mauna you pass through the clouds. I love to stop and fly right at the top of the cloud layer, where the fog lays in against the mountain. I am sorely disappointed on those mornings that the fog is not there!

The result of these flights is lot of great video, I just need to put something together to share it.

Of course a good video needs great music. I am indebted to Chris Stark, a local artist who graciously allowed me to use his track Dancing in the Rain as the backdrop for the video. I encourage you to head over to his website to check out his albums.
