Mauna Loa erupting

[Chas]

It is amazing the lengths they go to to prevent people from seeing an amazing spectacle despite the very low risk.

Did anyone else hear that?  Like 2 minutes ago? It sounded like an earthquake but nothing shook.  Social media 'exploding' with comments- looks like it was heard island wide.

Yep...we heard it in Wa'a Wa'a.

Heard it in HPP. Sound but no shake.

A good map that shows the location of the flow.[attachment=152]

A good map that shows the location of the flow.

The one problem I see with that map is Ken Hon, HVO's SIC, at today's 9am news conference, stated that the flow was following a low to the east of the 1935 flow, whereas that map shows it on top of and favoring the west of the 1935 flow. 

Not to say I know and all that, but only to point out the discrepancy..

It was based on a helicopter location while filming the flow. The flight was at 9:00 AM so could be new info or it could be wrong. It does give everyone a good idea where the flow front is in relation to Saddle Road.

It hit flat ground.. is now spreading out.. the road is probably many days away. Not to say it couldn't be sooner, but I suspect the pooling of lava on the saddle will change all sorts of things..

The road closure map makes no sense under the current conditions.

That would cut off access from Hilo side but let you drive up from Kona to the lava which is heading to Puu Huluhulu. Obviously not the plan.

Dane Dupont sez, "That loud boom many people around the island heard about an hour ago was a sonic boom from a jet - the sound was not related to the eruption of Mauna Loa." (Hawaii Tracker).

To be clear, USGS Volcanoes is a primary source on the jet boom explanation (although the twitterverse is skeptical)

Also, Pele's hairs are being found all the way down in the Pu'u Huluhulu area.

FWIW, the map author appears to have spent some time up on Mauna Loa helping with field studies and as a co-author of the related publication.

This doesn't mean the map is 100% accurate, and he doesn't appear to be local currently, and we all can all flub translating helicopter footage to map locations.

Thankfully the mapping precision and speed that was super important in 2018 to sort out which houses were affected and which were not isn't as important here currently. Ultimately, USGS has the better resources in this remote scenario unlike in 2018 when hundreds of community eyes were on the ground gathering and sharing first-hand info.
