Is Mauna Loa relevant to the TMT debate?

[HereOnThePrimalEdge]

And as far as the "facts" that HereOnThePrimalEdge gave us.. he/she/it is just blowing smoke

Which "facts" do you have an issue with?

It... lends weight to Goethe's felicitous description of architecture as 'frozen music.' ... Does this, I often wonder, make music 'defrosted architecture?' Listening to Bach's Goldberg variations as I often do on walks when motorway noise and other auditory intrusions preclude the music of silence, it strikes me that it might. - Pub Walks in Underhill Country, Nat Segnit

For those who may be interested, Mauna Kea may have last erupted 3,500 years ago not 200,000.

What does glaciated mean?

Leilanidude, How do you make changes here on PW without it showing that you edited your original version?

P.S. This recent link shows the volatility of Mauna Loa. Mauna Loa may be over due to erupt again.

Here is a map showing the likelihood of a volcanic eruption on the summit of Mauna Kea (Zone 7) & Mauna Loa (Zone 1):

Glaciated means that the snow/ice became so thick that it was capable of moving, downhill, like an ice river. A glacier is the term for it. Glacier National Park in far Northern Montana is a neat place to visit (in summer).

Suggesting that Mauna Kea is anything like Mauna Loa in terms of risk of eruption is ludicrous.

"What do astronomers think about Mauna Loa’s potential?"

It has no potential. Building an expensive telescope near the summit of an active volcano would be daft. Locating one on the slopes would be pointless; the lava flow and earthquake risk remain and there are plenty of other lower-altitude sites available.

How about 3 weeks ? In 1984 it came within 4 miles.

Snipped:
Mauna Loa erupted most recently in 1984. The eruption started at the summit (in Moku'aweoweo crater, which is the grey oblong area in the lower-left corner of the image to the left), extended in to the upper Southwest Rift Zone, and then migrated to the Northeast Rift Zone on the first day of the eruption. Volcanic activity remained in the northeast rift for 21 days. This sequence of events resulted in three flow units (shades of red to the left); the flows are numbered 1, 2 and 3 in the image. The a'a flow system from the lower vents achieved a maximum length of 27 km within a few days of inception of the eruption. The total lava flow was near 220 million m³. As eruption rates declined, the main a'a flow evolved from a simple narrow lobe with an efficient channel that delivered virtually the entire vent output to within 1 km of the flow toe, to an upright-stagnating channel system characterized by levees, blockages, ponds, and complexly branching overflows.

The gif, if clicked upon, will show larger size and how close the flow got to Hilo, in less than a week.

Am I missing something?

Perhaps, or maybe I should have said "weeks" instead of "less than a week." In either case, and as it concerns the construction of a billion dollar telescope on Mauna Loa, a lava flow there could destroy
an observatory on the summit quickly.

For an eruption heading for Hilo, there is a silver lining, however: Lava flows would likely take weeks if not months to reach the city, giving residents ample time to pack up and leave. But this is not true of all Mauna Loa eruptions.

As you mentioned in your previous post, relying on the historic record at best provides us with a few hundred years of data, and perhaps we need to view potential eruptions over a geological time frame:
Mauna Kea is far from extinct...
we're still a long long way from being free to think Mauna Kea is pau. We can't even count on there being no more activity from Kohala.
And Haleakala... erupted as recently as 1790.

You comments seem to allow that we should consider the possibility of a once in a 1000 year event or a once in 10,000 year event. Is that what you suggested?

If that's the case, we certainly can't rule out a massive 6 day flow from Mauna Loa to Hilo, any more than we can rule out a Mauna Kea eruption over a similar time period.

Actually if you had said "several months" it would have been closer to the truth.

OK, if you insist on splitting hairs, the historical record shows a possible flow of few weeks to a few months, as my link and others have pointed out.

Just as you have suggested the possibility of a Mauna Kea and Kohala eruption outside of historical evidence which suited your contention, I suggested a Mauna Loa eruption time frame slightly outside of historical evidence to indicate the rapid speed at which the lava can move.

I said less than a week.
You said nine months.

"Just blowing smoke" indeed.
Poof!* Like smoke, there comes a time to evanesce.
