Japanese Earthquake and Tsunami

Google Tsunami Alert

Following this morning’s (using GMT) earthquake just off Japan (now set at 8.8 on the Richter Scale, but it keeps rising as more information is analysed), I noticed that the Google search page has a Tsunami warning for all to see.

I thought I’d capture it for posterity.

Enormity

This truly is an enormous event, the TV videos this morning of the wave’s advance making this perfectly clear.  How and when it finishes, we can only watch and wait as one of the great forces of nature plays out before us.

Tsunami Transit Time for Japanese Tsunami of 11/3/11

Fortunately, the Tsunami warning system seems to be doing its job, and hopefully, those countries around the Pacific and the small Pacific Islands within have had enough time to warn folks to get to high ground.  This image shows how much time they’ve got!

 

NOAA Tsunami Warning @ 10:30 GMT

This is the state of play a short time ago and the actual alert, showing wave heights and periods out at sea.  When they hit the coast, things are very, very different.

EVALUATION

SEA LEVEL READINGS CONFIRM THAT A TSUNAMI HAS BEEN GENERATED

WHICH COULD CAUSE WIDESPREAD DAMAGE. AUTHORITIES SHOULD TAKE

APPROPRIATE ACTION IN RESPONSE TO THIS THREAT. THIS CENTER WILL

CONTINUE TO MONITOR SEA LEVEL DATA TO DETERMINE THE EXTENT AND

SEVERITY OF THE THREAT.

A TSUNAMI IS A SERIES OF WAVES AND THE FIRST WAVE MAY NOT BE THE

LARGEST. TSUNAMI WAVE HEIGHTS CANNOT BE PREDICTED AND CAN VARY

SIGNIFICANTLY ALONG A COAST DUE TO LOCAL EFFECTS. THE TIME FROM

ONE TSUNAMI WAVE TO THE NEXT CAN BE FIVE MINUTES TO AN HOUR, AND

THE THREAT CAN CONTINUE FOR MANY HOURS AS MULTIPLE WAVES ARRIVE.

FOR ALL AREAS – WHEN NO MAJOR WAVES ARE OBSERVED FOR TWO HOURS

AFTER THE ESTIMATED TIME OF ARRIVAL OR DAMAGING WAVES HAVE NOT

OCCURRED FOR AT LEAST TWO HOURS THEN LOCAL AUTHORITIES CAN ASSUME

THE THREAT IS PASSED. DANGER TO BOATS AND COASTAL STRUCTURES CAN

CONTINUE FOR SEVERAL HOURS DUE TO RAPID CURRENTS. AS LOCAL

CONDITIONS CAN CAUSE A WIDE VARIATION IN TSUNAMI WAVE ACTION THE

ALL CLEAR DETERMINATION MUST BE MADE BY LOCAL AUTHORITIES.

BULLETINS WILL BE ISSUED HOURLY OR SOONER IF CONDITIONS WARRANT.

THE TSUNAMI WARNING WILL REMAIN IN EFFECT UNTIL FURTHER NOTICE.

THE JAPAN METEOROLOGICAL AGENCY MAY ALSO ISSUE TSUNAMI MESSAGES

FOR THIS EVENT TO COUNTRIES IN THE NORTHWEST PACIFIC AND SOUTH

CHINA SEA REGION. IN CASE OF CONFLICTING INFORMATION… THE

MORE CONSERVATIVE INFORMATION SHOULD BE USED FOR SAFETY.

THE WEST COAST/ALASKA TSUNAMI WARNING CENTER WILL ISSUE PRODUCTS

FOR ALASKA…BRITISH COLUMBIA…WASHINGTON…OREGON…CALIFORNIA.

 

Wake Island

I wonder how Wake Island is getting on?  The highest point on the island is only 20 feet and the wave should be there about now….

Google StreetView is in Antarctica

Google Streetview Car spotted in Aberystwyth 03/06/09

Google Streetview Car

Although you can see how they’ve done it using the cameras and flags in the snow, it’s still really cute that they’ve given the appearance that the (in)famous Google Streetview Car has been that way. The Google Streetview Car is the one with the funny thing on its roof, NOT the bright yellow Type 2 camper with the westy conversion!

Shock and Loch Awe

Death Search

_45588222_loch226

Loch Awe

Four men, old enough and with enough experience of life to be able to look after themselves, have gone missing in Loch Awe.  Two have been found dead and the search is still on.    This of course is tragic, but I can well understand their situation.

Colony Holiday

When I was 16, I went on a “Colony Holiday” as it was called, run by the ‘Council for Colony Holidays for Schoolchildren’ (CCHS).  It’s got a new name now…  This holiday was at Inverliever Lodge, some log cabins a short way above Loch Awe, facing south.  It’s a wonderful, verdant, fresh place in summer.  The mosses and lichens grow to immense size on the rocks, oaks and birches in the little river valley close by.  The river flows into the loch with a little alluvial fan (see map) made of small flat stones, a few inches across.

Liever Island

Liever Island

On a fine warm day, in with a group of others, I was plodging around the water in the loch on this alluvial fan.  The water was lovely and warm.   On venturing further out into the loch, and when the water reached my thighs, suddenly the stones on which I was standing gave way – as if on the edge of a cliff.  I fell backwards in the same way as when going down a rock scree or sand dune.

I then became shockingly aware of this deeply unbearable, penetrating cold…

The water below about 80 – 100 cm is absolutely freezing, so I very quickly had to swim to the shallow as I realised the water was very cold and very deep.

Later, on checking the Ordnance Survey 1″ map, I found that the water only half a football pitch’s distance away was well over 100 feet deep!  It’s a classic case of an alluvial fan emptying into a glacially over-deepened valley, in this case, full of freshwater.

Men in Boat

The chaps in the loch, venturing out in a small boat, at night, before the equinox, in a Scottish Loch, in fog….?  If the boat tipped or because of some bravado, foolhardiness or accident they ended in the water, I can well imagine the shock they felt in the freezing darkness.  The water is of almost Arctic coldness, and being fresh not salt, it is not as buoyant as the sea so swimming in clothing is even more difficult.  It’s truly awful, and yet so close to shore, as the loch isn’t that wide.

Yoga, Leeches and More

  • When I emerged, freezing, from the lake, a leech was stuck to my leg.  I pulled it off, stuck it in a  jar and took it home as a pet – it lasted about six months.  Not knowing much about leeches, I gave it bits of meat, which rotted and stank.
  • Colony Holidays are still going under the ATE.org banner, Chris Green (tubby the tuba) retiring a few years ago, he told me.
  • The lodge (somewhat changed), is used for various activities.

River Liever Valley This yoga group describes it as, ‘… a new Yoga retreat Centre based on the principles of environmental awareness and the ability to source our energy and inspiration from the natural world. On the South facing banks of Loch Awe, surrounded by cascading waterfalls and forests, Inverliever Lodge is a place of high resonant energy, morning sun and glorious peace.’

The thing is that all guide books etc, always show a place at it’s best – like this Loch Awe Community Website…. – or even better, this Google Image Search.

Inverliever

Inverliever Lodge Webcam view in March

The EcoYoga webcam picture at the right gives a more realistic view of March weather which is wholly different to the summer weather I’ve witnessed, on such sites or seen in the Liever valley shot.  Something like this, but at night, is what the men ventured out into…

Why?

Postscript 7 Sep 2009

The two missing men were found over two months later.  Chief Inspector Andy Mosley said afterwards: “We believe at this stage that these two men may have been trapped under the water for some time. Remains in these circumstances often resurface after a period of time due to a number of factors, including water temperature and movement on the surface of the water. This process can also take longer in cold water lochs due to the extreme low water temperature. We are satisfied that our search has been as extensive as possible.

I can certainly vouch for the cold.  It’s awful.

Copenhagen Congress on Climate Change

In this stark summary from a meeting of 2.5k scientists from across the globe, we find that not only is anthropomorphic climate change real, not only is it getting worse, but also, within the error margins for the ‘hockey stick‘ predictions of only a few years back, recent measurements put the actual effects at the top of the predicted range!

Kongres Logo

Copenhagen, Denmark: Following a successful International Scientific Congress Climate Change: Global Risks, Challenges & Decisions

Many years ago I read a book (actually in a few volumes) by the late climatologist from East Anglia, H.H.Lamb called Climate Present Past and Future (ISBN 0-06-473881-7).  It’s extremely hard to get hold of now, but I recall that nearly everything Professor Lamb wrote is now coming true.

Many of the scientific concepts he wrote about are being used in the so-called ‘climate debate’ between various vested interests.  Check out the apologists for freedom at The Heartland Institute (you can’t make it up, can you?) or Climate Change Fraud (who change their hyperlinks regularly to avoid comebacks).  Several lone souls tackle these monsters of misleading fact-providers, such as Greenfyre’s and the Ecogeek.

The amount of cloud cover and water vapour is always a good red herring for the deniers.  As Prof. Lamb pointed out 30 years ago and is perfectly obvious to any observer, clouds are both insulators and reflectors of heat.  It just depends where they are, if it’s night or day, and where you, the observer are!  For instance:

  • cold day, -> clouds move in and night falls = cold night as cold trapped at ground level
  • cold day, -> no clouds at night = even colder night as heat radiates out to space
  • cold night, -> cloudy day = cold day as cold trapped under clouds and sun’s heat is reflected back to space
  • cold night, -> sunny day = warm day as sun warms earth’s surface

These temps are all relative, of course.  But throw in a bit of dirt into the clouds or let dirt fall on snow (another good reflector and insulator) and the picture changes because dark clouds and snow absorb more heat.  What is clear is that cloud and snow cover, like continuous volcanic eruptions, and like CO2 and CH4, are critical positive feedback agents.  Like trying to slowly push a light switch to stop in the middle, eventually all the slow forcing you do makes it flip to it’s other stable state.

Any worldary wobbling that the deniers use is also a red herring.  The wobble cycles tie in with ice-ages as Professor Lamb pointed out.  We’ve at least 20k years until the next one.  Bothered?  No.  Thought not.

The fact is that there are many scenarios for cloud behaviour and it’s influence – the climate change deniers just tend to use one (like the wobbles) as the basis of their arguments.  But even back in 1977, Professor Lamb’s models basically predicted the climate forcing we are witnessing now although at the time, a swing in the other direction looked possible.

But now we do know!

A recent exploration to the Arctic has been forced back because there’s no safe ice to walk on!  Coral is dying.  Floral and faunal species are being made extinct at an E.L.E. rate.  Make no mistake, it’s our fault and if we don’t pay now we or our children will pay in the future.  We need land and food to live on, not equities and price to earnings ratios.  A week of reduced fuel supplies in the UK and Europe and the continuing travails of African economic migrants revealed a tiny window on our probable future as billions, globally, seek somewhere to live and breed.  A few street riots will be the least of everyone’s worries.

I just wish that the OCO spacecraft had made it

The Bridgwater Egret

While walking George the dog today, I spotted an Egret in town! You can tell it’s an egret because nothing else is so brilliantly white. The seagulls and terns look dull in comparison!

This really shows the pace of global warming in my short lifetime.

When I first went to France in 1985 (after leaving Crawling Chaos in the lurch), I first spotted one of these gleaming birds on the salt-drying pans near Guerande.

The bird book I had, (The Hamlyn Guide to Birds of Britain and Europe: 1974 reprint), showed that this was it’s most northerly residence – and usually it was for summers only!  I’ve made a scan of the relevant entry from the page!  You can just see a tiny pink bit at the Loire Estuary…

Little Egret: Hamlyn

Since that time, I’ve spotted egrets in the Kingsbridge estuary in the South Hams of Devon, then on the nature reserve at Steart in summer, and now, near the centre of Bridgwater on the shortest day of the year!  Nowadays, the colony at Kingsbridge is thriving and taking up lots of the nest-sites of herons.  So it’s a bit of a puzzler for bird-fans what to do about it!

The northward march of the Egret that I’ve witnessed is in complete accord with the rapidly thinning and contracting North Polar ice sheet. The latest news (click on chart) is that the ice is going at a faster rate than even the best models have predicted. By the time I retire, there will be no ice, extrapolating by eye against the graph.
Of course, it means that anything that lives on or under the ice will die. i.e. polar bears etc on top and crabs and prawns underneath.

Something like this hasn’t happened since the Carboniferous era when trees grew as close to the poles as the 80° latitudes in both hemispheres!  The Earth became a hothouse for a time with raised oxygen levels giving rise to huge insects.  There then followed a period of extensive glaciation and mass extinctions.

We should all be afraid, very afraid. Climate can, and has done so in the past, flip very quickly between it’s stable states.
