How vapid.

Good, volcanic eruptions can ruin peoples day.

I mean look at Pompeii, people were in the middle of doing things.

but No volcanic eruptions is a good sign

I’ve been concerned for ten years or so about the lack of volcanic eruptions (actually producing lava) along the mid-ocean ridges of the Atlantic and Southern Oceans. That there haven’t been any is clear from the massive depth of the trench along the centre of these ridges.

If these eruptions hold off for thousands of years and then spew millions of tons of lava all at once then this could have a really significant effect on the world climate for decades and longer.

I’ve just confirmed my fears from the Global Volcanism Program database.

Since the beginning of recorded history of subsea volcanic action, dating back to 5050 BC there has not been a single volcanic eruption in the Indian or Southern Oceans. Over the same period there has not been a single volcanic eruption along any part of the mid-atlantic ridge.

The total number of confirmed Atlantic volcanic eruptions over that time is two. One in 1999 and one in 1865, neither anywhere near a mid-ocean ridge. The total number of unconfined volcanic eruptions in the Atlantic is three, in 1761, 1816 and 1836.

By way of contrast, the number of volcanic eruptions in the Pacific Ocean in recorded history is a massive 75.

that’s a bad sign

Found it….oddly enough it was in the systems information….who’d a thunk that then?!

They say the yellowstone park area in the US might blow one day.

One possibility, for example, is a new landmass the size of Iceland being made south of Perth.

What can we do to help?

Buy oxygen tanks.
Install sulphur dioxide scrubbers in your home.
Captive breeding of organisms that live along mid ocean ridges.

18 confirmed eruptions in Australia since 5850 BC.

But of those, none on the Australian mainland since 2900 BC.

I read that was one of the reasons our soil is farked, no volcanic activity spreading minerals around,

If you find one let me know. For instance, Australia and the Tasman Sea are loading over three volcanic hot spots (or possibly four). The two eastern ones through the Tasman Sea left behind island arcs. We can expect new volcanoes in the Tasman Sea any time now. The more familiar Australian hotspot came down the Great Dividing Range from Cape York through the Glasshouse Mountains to the Victorian Basalt fields before unexpectedly jogging west to the Volcanic province of South Australia. So the next one in that hotspot chain could be anywhere between Robe in SA and Flinders Island.

I mentioned a fourth. Just recently, geologically speaking, there has been volcanic action in the Torres Straight Islands. If this moves south, Australia’s next volcano could be on Cape York or in a nearby part of the Great Barrier Reef or Gulf of Carpentaria.

Australia is due for a new volcano.

Sounds like fun

Ill see if I can find a pre active list

In the very short term, website https://www.volcanodiscovery.com/erupting_volcanoes.html
includes “restless” volcanoes that may have a major eruption soon.

> The two eastern ones through the Tasman Sea left behind island arcs. We can expect new volcanoes in the Tasman Sea any time now.

Here’s one of the two. The second chain of volcanoes is further to the east.

The main reason being the age of our soils which is far older than the relatively recent latest volcanic activity.

This is part of why mollwoll is concerned.. Pressure needs releif. Hasn’t really blown a big infected blackhead for a good while, the skin of this earth we infest.

Yes, the other concern is that you have a giant rift valley about a km or so deep, faults make this valley deeper all the time, and it can only get so deep before a flood of very low viscosity lava full of sulphur dioxide and other gases fills it up.

To put it another way, 2.5 square kilometers of new sea floor is formed each year. But it’s been about 11,000 years since Iceland was formed, with nothing since then but a bit more volcanism around Iceland. So expect the next mid-ocean ridge eruption to generate 2.5*11,000 = 27,000 square kilometres of lava. By way of contrast, the 11,000 year old eruption that formed Iceland generated only 500 square kilometres of lava, which translates to 30 cubic kilometres of lava.

The ESA Sentinel satellite is measuring the ground movements that precede volcanic eruptions. Here is an example.

A Red Alert has been declared in southern Chile after the eruption of the Villarrica volcano early on 3 March. Thousands of residents in the area have been evacuated and the International Charter Space & Major Disasters has been activated by Chile’s risk management authority ONEMI.

Further to the operational support provided by the Charter, ESA and the DLR German Aerospace Center have teamed up to acquire and process Sentinel-1A imagery illustrating changes at the surface of the volcano. This image is a colour composite of the two Sentinel-1 scans from 20 February and 4 March; changes are visually enhanced by a Normalised Change Index (NCI) and some statistical computations. Pink and blue show changes in the radar signal caused by changes in the surface, while areas with no change between the two acquisitions appear grey.

This work was performed by DLR in the framework of the ASAPTERRA project originated by ESA.

Sentinel-1A is the first satellite for Europe’s Copernicus programme. With its radar vision, the Sentinel-1 mission provides an all-weather, day-and-night supply of imagery of Earth’s surface.

Although not yet in routine operations, Sentinel-1A currently provides a coverage every 12 days of relevant tectonic areas worldwide and is therefore very suitable to monitor events such as volcanic eruptions.

Aaah, great. The above image has come back. It went missing for a couple of days while Photobucket was doing its “maintenance”.
