Lava outbreak on Hawaii island

Thought some here might be interested. After two or three days of almost constant earthquakes in the Kilauea East Rift Zone, an outbreak of lava just occurred, unfortunately in a residential area. Around 10,000 people are being evacuated and things are a little uncertain right now as there is a possibility of further outbreaks nearby. I live about 10 miles away but am safe as there's high ground in the way, but imagine having lava suddenly erupt in your backyard - not good but people here are pulling together and helping their neighbours.

Have been following this with interest and concern, after noting the increasing number of earthquakes in the area showing on the USGS list.
Thanks for those video links.

No problem, Karearea. Initial reports mentioned the number of evacuees as 10,000 but seems the current number is closer to 2,000. The problem is that at the start of the fissure outbreaks the situation is very unpredictable and there's a trail of new cracks in the ground between Pu'u 'O'o (the crater that's been active since 1983) and the small town of Kapoho on the coast in east Puna. There are many populated areas in between so things may develop further over the next few hours or days. The earthquakes don't seem to have let up as of now which means magma is still moving along the rift.

Hardly a surprise as the entire Hawaiian island chain is a series of extinct, dormant or active volcanoes as you go from east to west as the tectonic plate slides across a thin active magma hot spot.

Main problem being that the supply of virgins to drop in to appease the gods seems to have dried up since the 1960s........

That was a rather large earthquake at 22:32:55 (UTC) - Magnitude 6.9, only 5km deep.

Yep, that wasn't a lot of fun - lasted around 20-30 seconds and was felt as far away as Kauai Island. There are now six separate fissures that are erupting and some areas are inaccessible due to dangerous sulphur dioxide emissions.

Going to be a long night. Better to lead the pack when evacuating than be on the tail end. Good luck to you.

Thank you, West Coast. Just to emphasize the amount of seismic activity at the moment, I captured this from the USGS just a few minutes ago. Buried somewhere in that mess is a 6.9 mag earthquake.

All very Hawaiian, Hokulea.

Here's to a safe evac and no tsunamis. I've been told there's rarely a minor quake in the island chain.

Commiserations. 20-30 seconds may not sound a long time, but it certainly feels like it when stuff is tumbling from the shelves and jumping off the floor. And you have to hold on to stay upright and you have no idea how long its going to last or how big it will get.

One recurring nightmare I have had since childhood is a volcano erupting not too far away and the ground all around me starting to grow hot, fissure and spit lava, leaving me unable to decide where to place my feet.

Yamagata Ken - you couldn't have described the feeling any better! The only thing I'd add is that every time you get an aftershock, you just grip whatever is nearest in the hope it's not going to happen again - or worse. We're used to large jolts here, but not something that goes on as long as this. Officially it was 40-seconds. I'm surprised I underestimated it but was about 20 miles from the epicenter so probably didn't get the 1st class experience.

As mentioned, the people who live out in the sticks are good neighbours and to the best of their ability will help their stricken brethren until the danger has passed. Those that live in the affected areas know the risks, lava being perhaps the least prevalent. The main degradation to life is the effects of VOG on the human lungs over time which certainly affected friends of mine who lived to the west of the Volcano, they always seemed to have a cough and be somewhat lethargic, although the Kona Gold that they enjoyed might have played a part ;-) By chance, my first visit was in late 1983 and I saw the 1500ft tall eruption at night, not realising how 'special' that was until years later. One thing's for sure, Kilauea will keep erupting for now, rest a while, then keep going long after 'we' are no more.

Well, hope it settles down.
My three earthquakes in 40 odd years hovering over this ring of fire have been curious rather than scary.
Bouncing up and down on metal grid flooring on the second floor as thousands of aircraft parts did little jigs on their metal shelves, a B727-200 hissing as it squatted on the gear, repeatedly, over me and a shaking patio door that I put down to the wind, wrongly, it turned out.

Re earthquakes. When I first visited Japan it was a real pleasure to experience my very first earthquake. I was in a cinema when suddenly the building moved and wobbled slightly. It was only when people around me starting screaming and jumping up that I realized, a) this is an earthquake, b) how exciting, and c) people here are genuinely scared of them. This third thought was interesting. Rather than getting used to them and growing inured, it was entirely the other way round. This I observed on many an occasion subsequently, such as at college when the classroom block swayed, and I could see the ornamental pond outside and the surface rippling and sloshing, and the students jumping up and running into the corridors; the chatter took several minutes to subside. The fear in the DNA?

Early one morning I was woken by a distant rumbling and cracking sound approaching fast. Suddenly the whole house shook above me and for a moment I wondered whether this would subside or grow even stronger. It was then that I felt genuine fear for the first time. As someone said above, that thought is frightening. Is this it? Somehow I had felt protected all my life, but here was a force that did not respect anything, and my own life meant nothing to it. Then I began to feel more able to understand the old legend of the giant catfish which awakes somewhere below the surface of the earth, and seriously needs to be appeased with incantations or whatever it takes.

Imagine waking up in the morning and finding this on the street outside your house.

I experienced my first real earthquake in New Zealand a few years ago and it was scary to me being from the U.K.
I am extremely pleased to say that, touch wood and whistle, I have never suffered like so many over here have over
the years, long may that continue I hope.

New Zealand has over twenty thousand earthquakes a year but luckily the vast majority are harmless.

Hokulea - that video of the lava flow down Leilani Avenue is stupendous. I cannot imagine staying anywhere in the vicinity.

Karearea - have to admit if that were my house I certainly wouldn't be on the roof taking that video - especially as the roof was a landing area for small lava bombs. On the other hand, most of the information those of us in Puna are receiving is coming from the residents of Leilani Estates that chose to remain despite the mandatory evacuation. The authorities here have supplied some less than useful information. For instance, there's now a new lava breakout which we're learning from local social media (confirmed by USGS cameras) that we probably wouldn't know about for several hours if left to civil defense.

I have only been in one earthquake and that is two too many for my liking! Although it was in California and only (!) a 5.6, I didn't like it - although there wasn't an embarrassing accident because it was 7am and I was sitting in the bathroom having a sh*t!!
