View Full Version : Mauna Loa eruption?

OK, anybody living on the Big Island, what gives with the reports that Maunaloa will be erupting soon? You guys felt any big quakes in Kona or Hilo recently?
The news reports say there are lots of spendy resorts built along the base of Maunaloa now. Is the "eruption" more likely to be like the one at Kilauea, or is Maunaloa going to blow her top?

Looking at the Hawaiian Volcano Observatory's info (http://hvo.wr.usgs.gov/maunaloa/current/main.html#seismic), the biggest earthquake at Mauna Loa lately has only been about magnitude 3 or so - barely big enough to feel. And when Mauna Loa does blow, it'll probably behave a lot like it did during its 1984 eruption (http://hvo.wr.usgs.gov/maunaloa/history/1984.html), the one that almost reached Hilo. Unless, of course, it doesn't.

If the strongest one was only about 3, then it's going to be awhile before anything happens at Maunaloa. We get +3 magnitude quakes up here quite often too (we part of the same "Ring of Fire" tectonic plate that Hawaii and the rest of the Pacific Rim is on). The one we had about 3 years ago here was a 6.8 and it did significant damage to the older parts of Seattle (where all the brick buildings were).
And then, of course, about 24 years ago, the top blew off of Mt. St. Helens. It's taken about 20 years before things started slowly growing again amid the volcanic ash. It was a truly eery place to visit.

The above map will help explain what I'm saying.
Mauna Loa is what I call a triple play threat.
There has been lava flows that have gone into
South Kona, Ka'u,Hilo and towards to South Kohala.
The South Kohala flow occured in 1859. The Hilton
Waikoloa Village and Waikoloa Resorts sit on the
1859 lava flow from Mauna Loa. The threat area
goes all the way north to Puako.
The major South Kona flows occured in 1950.
It cut off the road and destroyed houses. The
flows made from the summit to the ocean in
a matter of hours. On top of this there has
been numerous other flows from mauna Loa
that have gone through Ka'u and South Kona.
Hawaiiian Ocean View Estates sits on a bunch
of Mauna Loa flows.
The flows that have gone towards Hilo, the
closest they have came was 5.3 miles from
Kaumana, which is outside of Hilo [The 1984 flow] .
There was other flows like 1935 and 1942 that
the military tried to divert the flows using bombs.
Specifically if you go up to Mauna Kea Observatories,
you can see the 1935 flow where the lava pooled
into a big lake by Puu Huluhulu [across from Mauna
Kea Access Road].

Mauna Loa isn't the type of volcano to explode it's top. It might overrun the affected places with lava.

Yeah, I was just reading stuff about Hawaiian volcanoes...you either have pahoehoe or a'a flows. I guess the pahoehoe stuff is the one that's more dangerous because that really flows quickly and wouldn't give people much time to evacuate if a flow did start.
Hopefully people on the Big Island who might be impacted already have planned emergency procedures, although in the case of a fast moving lava flow and if you live on an island, where could you go to avoid being caught up in it? At least up here on the mainland, we have lots of room to run to!

I drove up as far as you were allowed to go towards Mt. St. Helens in 1985. It was indeed eerie and extraordinarily impressive. The massive blowdowns of whole slopes of trees and the new crater walls really give you pause, especially when what you know of volcanoes is based on the Kilauea caldera and vents.
If anyone's interested in the power of volcanoes, I'd recommend Krakatoa, the recent book (http://www.amazon.com/exec/obidos/ASIN/0066212855/103-6067154-7161450) by Simon Winchester. An estimated 30,000 of the 40,000 deaths it caused were by tidal waves, and the worldwide sky was so red there's a theory (based, as I recall, on Munch's own journals) that it was the background for Munch's The Scream, the theft of which was recently in the news.

It's anybody's guess when Mauna Loa will go real active.
HVO scientist in charge George Swanson declines to comment on a date. This associated press story from 13 September 04 is the most current our newroom at KKBG-FM has: "Scientists observing Mauna Loa volcano say earthquake activity beneath the Big Islandsummit has increased in recent months. An eruption isn't imminent. But scientists say the recent seismic activity is an indication that the process is moving in that direction".
This statement ranon the Hawaii 1st News Minute for the 13th. There have been several magnitude 3.0 tremblors in the past few weeks--some strong enough to be felt in Hilo. I just hope both major volcanoes don't decide to pull a 1984 caper which sent two flows toward Hilo. Keep that canoe handy.......

Hey Russ:
Does Hawaii County have any sort of disaster preparedness plan available if there is a repeat of the 1984 lava flows or are they planning to use the same plans that are in place for tidal waves? Heh. If the flow was moving from inland toward the ocean (as opposed to the tidal wave coming from the ocean inland) I'm not sure running for higher ground is going to cut it in Hilo. I know the entire state does those tsunami warnings, but does Hilo have an evacuation plan in place for lava flows? I think Maui should also be thinking about things like this also, because Haleakala is only dormant, not extinct, and it has been throwing off small magnitude earthquakes too.

Hawaii County and the word prepared shouldn't be used in the same sentence. They use their civil defense messages over the radio to describe an intersection going from two way to four way stop. Can you imagine if Honolulu adopted a message system like that? There would be no normal programming on radio anymore, it would be a constant stream of road alerts with an occasional song or two.
Typically if Mauna Loa erupted, it would be a more casual eruption unlike Mount St. Helens. I was in Idaho when that mountain lost it's top and boy oh boy that was one incredable event to be at when it happened.

Good one, Craig! That's what I was trying to get at...citizens in Hawaii County shouldn't be cavalier about preparing for this kind of disaster. More than likely the flow would be of the pahoehoe (fast flowing) type which means they wouldn't have much time to escape. And would most of the citizenry in Hilo even know where to escape to? Not to be an alarmist or anything, but even up here, I am pretty much prepared for a disastrous earthquake or other catastrophy. We have our emergency kits (even supplies for the popokis) and know pretty much what we have to do if the earthquake hits while we're at work v. at home. All our fragile things in showcases are puttied down and most of the large pieces of furniture (including the fish tank) are strapped to the walls.
CD in Hilo should be educating the people about the things they could be doing to prepare for the eventuality (an eruption WILL happen, just noone knows exactly when). Even if it doesn't happen for years, it's still good to be prepared. Look at what happened to Hilo during the tsunamis in the 1940s and the one in the 1960s? How many people died?
If the flows came from both volcanoes and they funneled in the direction of Hilo, where would people go? You've got an ocean at your back and no room to run.

Miulang, I think you have an exaggerated idea of just how fast Hawaiian lava flows move. Believe me, there will be plenty of time for people to get out of the way. It's not at all like Mt. St. Helens if that is what you're worried about. For an example of what really can happen, you should read about what happened to the village of Kalapana in the 1980s when a lava flow from Kīlauea covered the whole place. It took months.

If a lava flow from Mauna Loa threatens Hilo, there will be time to escape. The best land escape would be to go across the Wailuku river (over the humming bridge) and just stay north of Hilo proper. The Wailuku river (I think) is the dividing line between Mauna Kea and Mauna Loa in the lower ends of Hilo. Generally just head north and you'd be okay.

And if both volcanos erupted at the same time, would going north still be an option? And do people have emergency kits packed (clothes, some food, etc) so they can at least be reasonably comfortable if they have to evacuate? Can't rely on the Red Cross (or ohana) for everything.

You and I and most people know including geologists at HVO know that the chances of Mauna Kea and Mauna Loa erupting at the same time is next to zero. Mauna Kea hasn't erupted in several thousand years and many consider it extinct, though I think I read that it is officially dormant.
As far as people being prepared for most disasters, most people are not. What I only wanted to say in my original post to this topic is that the North area of the Big Island, Hamakua, Waimea, Kohala are the safe places to be should a catastrophic or even long term Mauna Loa eruption sends lava down the eastern and southern flanks.
I agree people should be prepared. The Red Cross, CD and other agenices are usually only there to provide the most basic of necessities and usually only for a short term.
The island is big enough to handle a dramatic shift in population to the North and there are routes of escape in the North to get off the island if need be.

Greetings Miulang....Craig's and Mel's reply say it all when it comes to preparedness here. Since my wife and I live in Laupahoehoe, we appear to be out of the immediate danger zone. The real problem comes for those nesting at Hawaiian Ocean View Estates on the southwest flank of Mauna Loa. The slope there is fairly steep...I recall Harry Kim mentioning this several years ago when he was civil defense chief here. Kim felt the lava would move fairly fast on this flank...much faster than in areas near Hilo. A prudent Big Island resident would have a survival kit which I keep in the car. I always keep the gas tank at least half-full in the event a flow or earthquake kills the electricity. Power outtages are common here. Many of us are just too complacent when it comes to the rumblings of mother nature. You wouldn't believe the traffic mess created by rain-induced landslides along the Hamakua Coast. All part of the fun in the outter reaches of the Empire. Thanks for your concern and well-honed observations. My canoe is ready....Russ

You're a man after me own heart! :) When you prepare for something like this, in some ways it might actually help forestall disaster. I think that's why we have insurance on our health and our cars (and why the insurance industry makes so much kala off of us): If you prepare like that, the likelihood of your needing to use it is far less than your not being prepared and being sent upriver without the proverbial canoe...

One good thing about being near the shoreline at HPP in Kea'au is that you'll know if you're in danger because all the coqui's will stop if at night, or you'll see the Ohia trees afire up by the fire station on 21st street long before it would reach me.
If we're cut off because the Pahoa Highway was inundated with lava, because we're so out in the boonies, we're on catchment and have satellite. Most of us have some sort of back up generator all ready because of HELCO's rolling black outs. We shop at Costco so we're stocked. Our homes are built on solid rock so very little chance of soil liquification.
I have two 20lb propane cylinders and my Weber Gas grill ready for the days without power or a great lava party. My neighbor is off the power grid with 13 solar photovoltaic panels powering her entire home. My elderly mother and father live with me (yes I asked them to live with us) and they're from the old days so our food pantry is typically overstocked with canned goods and lots of toilet paper (remember the dock strike of the 70's). We keep a few gallons of Clorox handy for water purification just in case and in the event of a moderate lava flow, I have five to six foot high stone walls surrounding my one-acre property with two driveways on perpendicular sides of my lot so if one side gets dammed, I still have another side to get in and out. We have several tarps two hand-crank radio's, two 1-million Candle Power spotlights, four FRS two-way radio's, one full power CB radio, lots of batteries, one 400-watt power inverter, and two 5000-gallon water catchment tanks on high ground with a five foot ditch around the low side, plus two 6-foot high 400 sq foot lava plateaus on the steep graded side of our property just in case you need a lava proof high ground.
I think we're prepared if in the event we cannot leave because of some hollywood-fast pahoehoe lava should flood our area. But as was said earlier, even pahoehoe travels like molassas on a cold day..."Oh my gosh! here comes the lava, I'm walking as fast as I can should I slow down?"

According to the local news reports, it's mostly steam (which is good) and there isn't too much upper level wind, so whatever ash there is will probably remain within the crater or close to it.

This article says Mauna Loa is in the midst of building itself up. Same thing is going on here at Mt. St. Helens. Since October, there has been a dome building up in the middle that's now 750 feet high. The volcanologists predict that if the activity remains at the level it's been at lately (they doubt that activity can be sustained for a long period of time), maybe in 10-20 years Mt. St. Helens will once again look like it did before it blew its top. We went down to see it last weekend. Pretty awesome. So peaceful and quiet (we were about 10 miles away from the activity); only indication of any activity was the puffs of steam.

...An estimated 30,000 of the 40,000 deaths it caused were by tidal waves, and the worldwide sky was so red....
Everyone and anyone can easily live through a '"tidal wave". Mainly
becuase "tidal waves" are waves caused by the tides - They are the
ordinary waves people see on the ocean.
"Tidal Wave" as it is applied by many, is an egregious misnomer for a
type of wave that has nothing whatsoever to do with tides or
tide-producing forces.
This is a too-common misconception. Merriam Webster notwithstanding...
It is a term that seismologists hate. What many erroneously call
"tidal waves" is actually "tsunami" or seismic sea wave.

But if that tidal wave was big enough and not caused by seismic activity (such as a mammoth hurricane or a metor) it could cause some major damage and death.
And like a Tsunami, it's just a wave generated by seismic activity. And as such back in the early 70's a 6-inch tall tsunami hit the shores of Kahala and drove inland for quite some distance.
