Trek to the Lava

The lava has been entering the sea for over a month now. I have wanted to hike out, but life and other commitments have consistently intervened. With off-island guests, I made the offer to lead a hike out to the flowing lava. My sister-in-law Darcy was the only one that took me up on the offer, the prospect of a 2am wake-up and a two hour trek across rough ground too much for some. We left the others in bed.

This is the same plan I have used before, a two hour run across the island to Kalapana gets us to the edge of the flow field about 4am. This leaves another two hours to hike to the lava flows. We would need the time! It would take all of that two hours to make just 2.7miles. Two hours over the rough ground of older lava flows, avoiding pits, loose plates, large cracks and small hummocks that rose 10-20feet overhead. This was in pitch black conditions with no moonlight to help. It was alternating bright stars and clouds overhead, two brief showers left us dampened but comfortable in the warm tropical dawn.

A Bright Glow from Halema’uma’u

It caught everyone’s attention, suddenly the southern sky lit up, a bright glow coming from the direction of our volcano. This occurred about 21:45 last night, we were getting ready to put away the telescopes, ending a great evening at the Mauna Kea Visitor Information Center.

The red glow was unmistakeable, something was happening at Halemau’uma’u. We moved to where we could see the brightly lit plume over the volcano, conversation buzzing with questions, what is going on?

Our guess is that something, most likely a large rockfall, disturbed the lava lake at the bottom of Halema’uma’u crater. The lake, normally crusted over and dark, can be easily disturbed. If something happens to break up the crust, the glow of this very hot lava is surprisingly bright. Bright enough that we were surprised by the show from our vantage point about 30 miles away.

What happened? I will have to read the daily report later today and see if anything out of the ordinary is noted. A nice event, and a treat for the tourists still at the VIS near closing. The glow faded over the next 20-30 minutes. After closing the VIS and beginning my drive back down the mountain, it had faded enough to be barely visible again.

My Canon G11 is not normally a good after dark camera, but given the bright moonlight, and the brighter glow from the volcano, it did fairly well…

Update! Today’s volcano report indicates a series of large rockfalls occurred last night.
