Lava flow update - Kapohocat - 12-02-2013
I know I havent been paying attention but the info that lava is coming to Pahoa made it's way via Punaweb to the east coast to FB with a stop in Cali and now back to Kapoho...
Whats up with the flow? When I looked today at the Nov 21 update it's looking like a slow puttering on the HA side towards Pahoa.
I tried to find that topo map link someone posted the last time it went towards Pahoa but must be archived somewhere or I was incorrrect search words.

It doesn't seem to be moving anywhere quickly in the last week - just a few small breakouts laterally from the main flow. Note that all of the recent flows North of the rift line tend to be fairly short before a downhill Southerly flow steals all their lava. I don't think there's anything to get excited about quite yet. If you forget where *this* post is, just google "Kilauea status" to find USGS site.

Lets say that this current flow continues this way for say the next 5 years?. Looking at all the lava that came down kalapana the last 5 years, makes me wonder about the next 5 years at this direction its on now. Maybe someone can help answer a few questions I have?. With all the lava up at the summit right now, could that be effecting the lava out put at pu'o?. Are these two vents working together on one volcano?. If so, this eruption looks to only be getting started the last 30 years or so?. How long have past eruptions lasted on the east rift zone, any thing like this before 83?. With so much more new coastline and added land mass, also makes me curious how the island will react to the next Big earthquake?. Some of these mountain slopes look like they have had large land slides in the past?. Anyone know how much lava approximately is under Kilauea at any given time? Or if this amount is lessoning or growing?.

The Atlas of Hawaii by Juvik has an extensive set of maps of past land slides from all the Islands, they are eye opening to say the least. All these Islands were once as big as ours is, but one of the forces that reduced them to their current sizes has been land sides. The added weight here on the East side will eventually trigger some significant earthquakes as the island as the island adjusts to the changes.

The usgs website is one of the best resources for some of your questions, and the scientists up at HVO & UH-H Geology have many public forums, so there are many opportunities to meet with them.
The USGS History page may help get with some of the past historical info:
http://hvo.wr.usgs.gov/kilauea/history/main.html
UH press topo map (available at many stores) & USGS both have awesome maps that have the historical flows on the island mapped out

From the few meetings I have gone to
The Pu`u O`o eruption is not in any way a "normal" eruption, either for Kilauea or any other observed volcano. The current almost 31 year eruption has been breaking records for longest eruption for a number of years now, so any questions on the normal of this eruption is that it is all new science being made every year. But the scientists estimate that approximately 90% of Kilauea Mountain have had lava coverage since human contact & 60% of Mauna Loa Mountain...so there is ALWAYS the potential of lava flow on these two very active volcanos.
The scientists have some indications that the Halema`uma`u Crater & Pu`u O`o may have connectivity, but are they 100% positive? doesn't appear they are that sure.... but they do often report the similarities with the inflates & levels in the status:
http://hvo.wr.usgs.gov/activity/kilaueastatus.php
The island reaction to earthquakes (more accurate is that the islands movement & density changes cause the earthquakes....) can be anything from nothing to fissures to subduction (the 1975 earthquake had a localized deviation that was catastrophic to campers in the area) to uplift (the Wood Valley ridge is a massive uplift feature) to horrendous slump events (think the Huge valleys on the NE of the island, including Waipio.... there are debates on wether some of the slump were single action land slides....and there are indications that the resultant tsunamis were Indo-Pac catastrophes - debris in Royal Gorge Park in Australia matches some on these islands...at over 300 meter elevation...
Of course the 1975 earthquake & many of the more recent micro ones are along a fault line that is the slide-plate of Kilauea sliding down the slope of Mauna Loa...this movement has been ongoing for a very long time....
And the real volcano danger on this island is Mauna Loa... the yearly lava output of Kilauea is nothing compared what Mauna Loa can produce....and the speed of Mauna Loa flows versus Kilauea can be rift to ocean in hours rather than Kilaueas weeks to months speed.
RE: Lava flow update - bananahead - 12-02-2013
far from an expert here...
but heres my take and opinion.... its going slow not enough volume, and it would have to sustain good flow for quite a while for the tube to form that far... I bet it peters out soon...... some people are saying Pahoa Ainaloa Makuu because the topographical maps show that way as more downhill than towards Kalapana, Eden Roc, HA, etc. but you never know it may stay on flat ground or run into a channel so can change direction i guess, its not real steep over there ...looks like most of that area is about 1-2 miles for 200' drop in elevation, unlike Holei Pali which has areas that drop over 1,000' in less than a mile, most of the flows in last 30+ years have been towards the Holei Pali area (south) which is quite steep (for Puna) until the flats of the shore.
same with before that ca1970 when Mauna Ulu went off with its 1500'+ fountain and filled in all those craters and is the flow you see in the lower part of the park now...
it changes all the time, even in recorded history

Cat, I think you were referring to this thread, the images started with the overlays by Glennoid on pg 9, but do not seem to be supported:

The links below are to maps showing all the lava flows on this island. Warning some of the files are huge so you may want to download first. Some of the past flows such as the Ai Laau flow which covered most of Puna apparently lasted for several hundred years.

RE: Lava flow update - DanielP - 12-03-2013
There was a channelized flow several years ago that reached out that direction, but ceased with the Thanksgiving Eve breakout, to the best of my recollection. I believe this was episode 58 in 2007.
