Hi folks.

I was very interested to see that Hawaii Civil Defense had to put out a statement regarding the rumors that some sites and some parts of social media [not me] were perhaps strongly suggesting there is the potential for a mega tsunami and large earthquake surrounding the current activity in Hawaii. I was surprised because a couple of my posts ago I nattered on about the doco series regarding the southern flank of Kilauea. Of course the Civil Defense needing to respond to such rumors was a pure coincidence with my second last post. I am not into fear mongering and of course the Civil Defense statement had nothing to do with my mentioning of the doco I talked about. I did a search of sites and posts which the Civil Defense were perhaps responding to and found some referring to a possible disaster scenario.

Now, I feel that the activity in Hawaii is unnerving and is terrible that it has claimed people's homes and properties. No-one can predict 100% what the ultimate scenario is for this volcano and all associated tremors/quakes. I hope that, as I said in a previous post, that the lava pushing it's way to the east mostly, will help to alleviate any potential pressure placed on the southern flank and, over time, all will settle. Time will tell. Not being a scientist in any realm, it is not for me to assume knowledge or predicting any impending doom for any region as a result of volcanoes or quakes. I would never do that. My interest in these subjects is researching [where I can] and info gathering to improve my knowledge.

Hawaii's activity is no doubt interesting and a learning experience [of the behaviour of volcanoes and associated tremors]. But ultimately and primarily, my observation of this situation, like may others, is in caring about the welfare of the folks over there who are facing this disaster. I am also particularly focused on Hawaii atm., as I have friends travelling there next week [if they will be able to] and we are keeping an eye on the situation.

An M4+ has come up in the Leilani Estates region an hour ago, amongst other tremors involving the volcanic activity. The tremor activity is fairly constant, but there are times when the tremors come up in a clusters too when the pressure builds and momentarily focuses on one or two spots. Apparently there are 21 fissures now, with one fissure in particular showing renewed/heightened activity.

Let's hope the Hawaiian activity settles soon.

For now, Duck.

Duck, Iíve heard similar with a mega tsunamis also likely to threaten Australia.

Hi Kino.

Yes, I have seen, over time, various discussions elsewhere on the net regarding the potential of mega tsunamis affecting the Australian coastline. Earthquakes, shelf [sea] collapses, volcanoes, asteroids and so on can be the instigators of such. I am sure since the dawn of time there have been mega tsunamis affecting Oz.

On the Bureau of Meteorology Australia website there is a list of recorded [since records were established in Oz] tsunami effects on the Oz coastlines. here.

With the nature and potential of events Mother Earth can cook up sometimes, there will be chances of varying degrees for a fairly rare mega tsunami to affect us again. As the BOM site page shows, mega tsunamis in other places in the world can travel far enough to affect our coastlines. So many cities are built on or close to the waterline in so many countries, that these days a mega tsunami could have some serious consequences for many countries. We will see another large tsunami somewhere sometime, unfortunately. But when...I dunno.

A long time ago, we got swamped on the Cowes [Phillip Island] beach by a tremendous 'wash' of water which rushed around the island. One of my sons nearly got swept out in the current. It shocked the you-know-what out of us and him. It was such unusual behaviour, I wondered if it was the after effect of a sea quake - meaning a tsunami - but never found out what caused it.

Cheers, Duck.

Hi folks.

The tremors/quakes are obviously ongoing and fluctuating in Hawaii.
I found [if I haven't already put this link in before?] a link to the USGS offering their statement on the south flank of Kilauea and wanting to debunk the notion being put forward on some sites/blogs etc., that the south flank will slump and cause a mega tsunami. In the link the USGS offer very interesting history and info on this topic. Again, for me, it is information that adds to my understanding of volcanoes, quakes etc..

The USGS info on the south flank of Kilauea

NZ {Kermadecs} have come up with some decent quakes today. M6.2 was the biggest so far. This activity falls into place with what I was suspecting may occur near or on NZ. Other locations in the Pacific, such as Japan, seem to have a heightened potential for M5+'s too [Japan has had one}.
There have been [and possibly will be more to come] several decent sized quakes popping up around the Ring of Fire in the last 24 hours or so.

Iceland came up with a quake M4.2.

The Mediterranean has had it's share of small tremors too, as has the countries to its east and west - see Euro and Middle East tremors

PNG and/or Vanuatu [or nearby island] may {or may not} come up with a quake yet.

A location/words that came to mind Barren or Barrow or Baron for some reason - may mean nothing. Or another location starting with the letter 'B'....????

For now, Duck.

Beautiful and incredible image. I have to admit I had to check it out to see if it was fake - does not look like it is! Was taken at the same location in 2009. Caption reads: "Hot lava pouring from the Kilauea volcano in Hawaii creates vortexes of steam in the Pacific Ocean"

Thanks Kev
Found an article on Business Insider, apparently from 2009.
https://www.businessinsider.com.au/hawaiian-lava-steam-vortices-tornadoes-2017-6?r=US&IR=T

It inspired me to look further, and it's mind blowing to look at lava and the sea.

How good is that. 20 yrs back I stood at mt yasurís rim and watched it play up, itís awesome and mesmerising all at once watching a volcano up close.

Hi BIG T and all.

Yes, it is mesmerizing BIG T. To think this started out as a crack in the road/ground - showed inflation and separation up to 6 feet [approx] - with people looking down into to hole - and then it took off. Amazing.

Rusty the Rooster - who is becoming an internet hit - keeps crowing in the background. And there is a tree which stood valiantly in the lava flow path which people named Piney. Not sure if has succumbed to the flow - some say it has, others no.

But above all, it is still a sad thing for folks to have lost their properties and some of their animals.

There was an M5 volcanic explosion earlier, which would have been incredible to feel.

The footage coming from the youtube feed is from a camera set up in someone's house [I believe] - with the owners allowing the crew to stay there [if I have my info correct]. The house is about 300 yards or feet [can't remember what they said measurement wise] from the fissures and new volcanic mound forming. The volcanic mound may be a bit further from the house than the fissures closer the Kilauea volcano.

Amazing footage of this event and hope all folks there stay safe.

There are a couple of translations for Rusty the Rooster in Hawaiian. I reckon they could name the new volcanic mount/crater after him - ʻo ia ka moa. After all it is near his home. He has become so popular in this extraordinary event, and not to sound silly, I think it is a good name for the new volcanic feature.

Anyway, there are quite a few M5's coming up around the plane atm., and an interesting one came up in the Tasman Sea - just east of near the Vic and NSW border....

For now, Duck.

Interesting Tsunami talk.

I always try to find signs of where water worn rocks are located well above tide marks.

Bass Point in the Shellharbour region is a good one. In the current drought with grass thin you can see at a local surfing spot called the Shallows that the soil at least 50 metres inland into grass, and elevated perhaps 5m to 7m has lots of rounded material.

The south side however is more dramatic with large boulders pushed right up to the first lines of vegetation. I have probably seen a sea big enough to have a wave reach that area, but hardly enough to push a grain of sand let alone a rock weighing as much as a car.

At Port Kembla there are a couple of rocks on the clay/sand hill above honeycomb rocks that do not belong, rounded volcanic rocks from a dyke much further below. May post picture tonight.

I vaguely recall a geography lesson from HS (teacher was Alan Hardy from Shellharbour) who told us they'd discovered at one time, sand & associated debris on the western side of Lake Illawarra, believed to be from a Tsunamis. That's a decent sized wave.

Hi folks.

Yep, I reckon in the life of our continent there have been events of larger tsunamis which have deposited various 'things' inland. I also believe [in my own mind] that lands around the world have risen and fallen as well, and this can be why, in some locations, sea items [shells, fossilized sea creatures etc.,] have been found in cliffs and inland formations. Fascinating stuff.

Not only mentioning the above, we have many places in Oz where you can find lava deposits. There are quite a few ancient/old volcanic regions on our continent and into the seas around us.

Just looking at all of the quakes in Mayotte [NW of Madagascar], I have a bit of a feeling that these movements may be related to their volcanic systems. I hope I am wrong, and just may well be.

Other moderately sized quakes have popped up in various places too, and it seems that there has been an increase in such across the planet. I wouldn't mind betting [just a little] that we will see some other volcanic behaviours in some regions too, other than Hawaii.

There has been an interesting 'circle' of 4 [which actually makes a square] of tremors come up in New Mexico, Oklahoma and Texas, within a very short space of time today. Just looking at the USGS map, there was also one in Tennessee - which became part of a line from east to west and visa-versa - when you momentarily forget the 'square' I just mentioned. here

On listening to some of the audio from the Honolulu Civil Beat live feed, it is sad to hear the chat from some of the folks that have lost their properties. Other commentary from the videographers and other knowledgeable folks is interesting - learning about this situation there on the Big Island. Some of the earthquakes/volcanic quakes there have been loud rumbles and the volcanic action itself is incredibly loud sometimes.

I still get a horrible feeling that we may see an M7+ somewhere, sometime soon. I dunno where, but it feels to me that there is possibly energy potential enough to throw one up somewhere....I could be very wrong.

More quakes to come for the globe - I reckon on the M5 scale. Maybe with an M6 or two. Will see.

Oz may come up with a few more tremors too - one offshore and maybe one on the coast, and maybe a few inland and maybe one in the red centre. Will see.....

For now, Duck.

When I lived in Maleny (Queensland) the locals said there was oral history of a tsunami in the past that came in almost as far as Nambour.
