(12-02-2022, 08:49 PM)My 2 cents Wrote: It seems to me that if you are intent on putting a road through an area that is prone to lava flows, in a lot of cases it would be best to put it right on top of the most recent flow. Especially in flat, level areas.
In these areas the flow tends to inflate and reach substantial thicknesses. So wouldn’t a subsequent flow tend to go alongside the previous one, rather than on top of it?
I know there are plenty of variables and these are just my ramblings, but don’t you think there might be more to the decision than “easier to grade”?
Perhaps it would have been even more sensible to have built the new highway a few hundred yards to the north in the most vulnerable area to ML lava flows, i.e., just a little way up on the slopes of Mauna Kea? I realize that might be private land, but building a modern highway where lava would pool near the MK and ML access roads could have been avoided.
