Another landslide and its aftermath

Dealing with a Landslide

One of my favourite blogs - The Landslide Blog - has three posts about a major landslide on the Jinsha River on the borders of Tibet and Sichuan. The slide blocked the river and a huge lake formed. See HERE.

The landslide


The lake formed

Bolo flooded

Then huge efforts were made to breach the landslide - it looks as if a lot of material was removed. HERE is the blog about that.

A view from upstream of the Jinsha River landslide showing the lowering of the landslide and the cutting of a breach.

But repairing something like this causes damage. You can read about this HERE. Bridges were destroyed downstream.

Before and after photos of a bridge downstream destroyed by the water released by the breaching. It would have been rather worse if the landslide had been allowed to wash away and the flood to come unexpectedly.

This video shows the power of the water running through the landslide.

Newly discovered impact crater?

Is there Something Under the Ice?

A source has brought this article from the BBC to my attention. It is based on this article in a scientific journal.

The suggestion is that there is a meteor impact crater under the Greenland Ice Sheet in North West Greenland. I rather like the fact that the Hiawatha Glacier runs over the supposed impact crater.

From various strands of evidence it is suggested that the 31 km wide depression, under almost a km of ice, was created by the impact of a 1.5 km wide iron asteroid sometime between 12,000 and three million years ago. No one has actually seen the crater or identified parts of the asteroid as yet. 

There is a suggestion that it is connected with the Cape York meteorite and the Younger Dryas. But much more information needs to be collected before informed speculation can begin. Uninformed speculation is straining at the leash!

Visit a fault scarp

Possible Field Trip?

If I ignore that this is in New Zealand, a field trip beckons to look at this fault scarp!



The scarp developed as a result of the magnitude 7.8 earthquake of the 14th November 2016. it is about 3.5m high.

You can get more details and lots more photos HERE

NICK CHIDLAW - GEOLOGICAL WALK
WHEN
SATURDAY, 17 NOV 2018
WHERE
GLOUCESTERSHIRE, UK (MAP)
DESCRIPTION
ICE AGE & HOT DESERT: TWO GEOLOGICAL WALKS NEAR GLOUCESTER (SATURDAY 17TH NOVEMBER)



THE SEVERN VALLEY IMMEDIATELY NORTH OF GLOUCESTER COMPRISES A RURAL LANDSCAPE OF FARMLAND AND SCATTERED VILLAGES, PUNCTUATED BY ABRUPT, FLAT-TOPPED HILLS, AND EXTENSIVE TRACTS OF VALLEY FLOOR OVER WHICH THE TIDAL RIVER FLOWS SOUTH. THE GEOLOGICAL HISTORY OF THE AREA IS FASCINATING AND CONTRASTING. THE OLDEST STRATA, C. 200 MILLION YEARS OLD, ARE VERY GENTLY FOLDED INTO A BASIN STRUCTURE AND WERE LAID DOWN AS HOT DESERTS GAVE WAY TO SHALLOW TROPICAL SEAS IN LATE TRIASSIC / EARLY JURASSIC TIMES. THEY ARE EXPOSED IN CLIFFS ALONG THE RIVER. THE HILL TOPS AND VALLEY SIDES BELOW PRESERVE DEPOSITS LAID DOWN BY A GLACIER AND MELTWATERS DURING THE ICE AGE. AT THIS TIME, THE RIVER PROGRESSIVELY CUT DOWN ITS COURSE, AT ONE TIME REACHING BELOW ITS PRESENT LEVEL. WITH THE ENDING OF THE ICE AGE IN BRITAIN SOME 10,000 YEARS AGO, AND THE ASSOCIATED RISE IN SEA LEVEL, THE RIVER HAS BUILT UP ITS BROAD CLAYEY PLAIN, FREQUENTLY PRONE TO HAZARDOUS WINTER FLOODS. THIS COURSE COMPRISES A MORNING WALK (C. 4 MILES) AND AN AFTERNOON WALK (C. 3 MILES), BOTH GENTLY-PACED WITH FREQUENT STOPS TO DISCUSS THE GEOLOGY AND LANDFORMS.   



VOLUNTEER DRIVERS AMONGST THE FIELD PARTY WILL BE REQUIRED TO FACILITATE THE PLANNED WALKING - DO LET ME KNOW WHEN ENROLLING IF YOU CAN HELP IN THIS REGARD.  

TUITION FEE IS £27.00 PER PERSON PER COURSE.

IF YOU / ANYONE ELSE YOU KNOW WOULD LIKE TO ATTEND EITHER OR BOTH OF THESE COURSES, PLEASE FORWARD CHEQUE PAYABLE TO ME TO:

DR N CHIDLAW

8 SILVER STREET

DURSLEY,

GLOS.

GL11 4ND

BANK TRANS CAN BE ARRANGED IF YOU DO NOT USE CHEQUES - LET ME KNOW.

PLEASE PROVIDE ME WITH YOUR POSTAL ADDRESS - I WILL THEN BE ABLE TO SEND YOU YOUR COURSE HANDOUT(S) IN GOOD TIME BEFORE THE COURSES RUN, SHOULD THEY BECOME VIABLE.



THE DEADLINE FOR THE MINIMUM NUMBER (10) OF ENROLMENTS FOR BOTH COURSES IS THURSDAY 1ST NOVEMBER (JUST OVER 2 WEEKS BEFORE THE COURSES ARE PROPOSED TO RUN).   MAXIMUM NUMBER OF ENROLMENTS IS 30. IF THE MINIMUM OF ENROLMENTS IS REACHED BY THIS DEADLINE, THE ARRANGEMENTS WILL CONTINUE; IF NOT, THE COURSE WILL BE CANCELLED AND FEES RECEIVED WILL BE RETURNED TO THOSE WHO HAVE SENT THEM IN, SOON AFTERWARDS.

PLEASE NOTE THAT FOR EACH COURSE YOU WILL NEED TO:

ARRANGE YOUR OWN TRANSPORT (AND ACCOMMODATION SUCH AS B&B IF YOU LIVE BEYOND REASONABLE COMMUTING DISTANCE - TUTOR CAN ADVISE)

BRING YOUR OWN PACKED LUNCH(ES), AND ANY REFRESHMENTS (E.G. FLASK OF COFFEE, FRUIT JUICE, MINERAL WATER, HIGH ENERGY SNACKS ETC.)

WEAR STRONG FOOTWEAR WITH GOOD TREAD AND ANKLE SUPPORT, AND WARM WATERPROOF CLOTHING IF WEATHER IS POOR

WEAR HARD HATS WHEN BELOW ROCK FACES (BRING ONE, OR REQUEST FROM THE TUTOR IN ADVANCE OF THE COURSE(S) TO BORROW ONE)

YOU WOULD BE INSURED AGAINST ACCIDENT FOR THE DURATION OF BOTH COURSES.

Nick Chidlaw - Geological Walk
When
Sunday, 18 Nov 2018
Where
Gloucestershire, UK (map)
Description
A GEOLOGICAL WALK IN ESCARPMENT COUNTRY, MID COTSWOLDS: Jurassic strata and landforms near and far (Sunday 18th November)



The steep escarpment of Jurassic rocks in the mid Cotswolds looks north-west across the broad low-lying Severn Vale, to the Welsh Borderland hills and beyond. This mainly rural, highly attractive landscape overlies a geological legacy of repeated tectonic plate collision and extension, uplift and erosion going back to Precambrian times. On this course you can learn to recognise these landforms, know of their underlying rocks, and understand how both came into being. Walking about 4 miles between Doverow Hill near Stonehouse across the valley of the river Frome to Selsley Common, we examine exposures of Early and Middle Jurassic strata in old quarries and pits, and lane cuttings. The Early Jurassic rocks here, mostly soft, muddy and sandy sedimentary deposits, were laid down in warm tropical seas overlying an active rift complex before the North Atlantic Ocean basin opened to the west; the overlying Middle Jurassic strata, mostly limestones with highly fossiliferous beds, were deposited when the seas became shallower and clearer and the crustal rifting died down. In later geological times, the Jurassic strata came under north-south tension, causing the rocks to develop parallel sets of faults running east-west, and displacements to occur. During the Ice Age, the River Severn and its tributaries progressively incised their courses, and landslides occurred on the escarpment as it came into being; these landslides continued to take place, notably at the end of the last cold climatic episode.  



Volunteer drivers amongst the field party will be required to facilitate the planned walking - do let me know when enrolling if you can help in this regard.  

Tuition fee is £27.00 per person per course.

If you / anyone else you know would like to attend either or both of these courses, please forward cheque payable to me to:

Dr N Chidlaw

8 Silver Street

Dursley,

Glos.

GL11 4ND

Bank trans can be arranged if you do not use cheques - let me know.

Please provide me with your postal address - I will then be able to send you your course handout(s) in good time before the courses run, should they become viable.



The deadline for the minimum number (10) of enrolments for both courses is Thursday 1st November (just over 2 weeks before the courses are proposed to run).   Maximum number of enrolments is 30. If the minimum of enrolments is reached by this deadline, the arrangements will continue; if not, the course will be cancelled and fees received will be returned to those who have sent them in, soon afterwards.

Please note that for each course you will need to:

Arrange your own transport (and accommodation such as B&B if you live beyond reasonable commuting distance - tutor can advise)

Bring your own packed lunch(es), and any refreshments (e.g. flask of coffee, fruit juice, mineral water, high energy snacks etc.)

Wear strong footwear with good tread and ankle support, and warm waterproof clothing if weather is poor

Wear hard hats when below rock faces (bring one, or request from the tutor in advance of the course(s) to borrow one)

You would be insured against accident for the duration of both courses.

What to Do in a Landslide - Stay Well Back!



The video above, taken in the Philippines, shows the dangers of landslides, it starts off fairly innocuously but quickly becomes extremely life threatening - watch the man on the balustrade - he is lucky to be alive.

How to be paranoid!

More Things to Worry About!

I'm being a bit flippant about this but this article about Alpine Tsunamis is well worth reading. 

The danger - if you are in the mountains and a lake is nearby - is tsunamis. Tsunami is Japanese for "harbour wave" - a wave where there should not be waves. In Japan they are usually caused by earthquakes but landslides into water can also cause them.

And that is the danger in Alpine regions. The author describes various events with casualties ranging from five to 60,000. The greatest danger is with moraine dammed lakes. If the dam fails vast quantities of water can be released into highly populated valleys. This is called a GLOF - a Glacial Lake Outburst Flood.

And if you live near Laguna Paron in Peru beware of GLOFs.

Laguna Paron (Cordillera Blanca, Peru) in 2009, a lake dammed by the glacier Hatunraju with a capacity of 75 million cubic meters. The lake is surrounded by a 250 meters high moraine.  If this dam fails an outburst of around 50 million cubic meters could flood the valleys downstream.

Geological Sites of the Bristol Region (2018)

Geological Sites of the Bristol Region (2018)

This book has just been published. the foreword is by Professor Mike Benton and it costs £19.50. You can download some sample pages by clicking THIS LINK

You can get it from  the Bristol Museum shops at Bristol Museum and Art Gallery and M-Shed. Or visit their online shop HERE.




I bought the book last week from the City Museum. (NB closed on Mondays!)
It is not a standard excursion guide. The greater part of the book describes the most interesting RIGS sites, in alphabetical order, often in great detail. So to follow one geological period involves jumping from one part of the book to another. 

But it is good for its intended purpose - describing the geological sites of the Bristol Region.

The maps are fairly useless, you will need OS and Geological Survey maps to find your way about. But once on site the book is invaluable.

NEW FOSSIL DISCOVERIES FROM FRANCE AND MOROCCO SHED LIGHT ON THE ORIGIN OF STARFISH AND BRITTLE STARS IN THE GREAT ORDOVICIAN BIODIVERSIFICATION EVENT

DR AARON W. HUNTER - DEPARTMENT OF EARTH SCIENCES - UNIVERSITY OF CAMBRIDGE

ASTEROZOANS INCLUDING STARFISH (ASTEROIDS) AND THEIR CLOSE RELATIVES THE BRITTLE STARS (OPHIUROIDS) ARE AMONGST THE MOST INSTANTLY RECOGNISABLE AND ICONIC MARINE ANIMALS. THEY ARE A DOMINANT AND SUCCESSFUL GROUP OF LIVING ECHINODERMS BASED ON THEIR DIVERSITY, ABUNDANCE, AND BIOGEOGRAPHIC DISTRIBUTION. DESPITE THEIR ECOLOGICAL SUCCESS AND A FOSSIL RECORD SPANNING MORE THAN 480 MILLION YEARS, THE EARLY EVOLUTION OF ASTEROZOANS AND THEIR ECHINODERM COUSINS MORE GENERALLY, REMAINS A MYSTERY. IN-FACT, THEY SEEM TO APPEAR SUDDENLY IN THE EARLY ORDOVICIAN WITH NO APPARENT ANCESTOR IN THE CAMBRIAN. NEW DISCOVERIES FROM FRANCE AND MOROCCO HAVE BEGUN TO RESOLVE THIS MYSTERY.

EXCEPTIONALLY PRESERVED FOSSILS, COMBINED WITH AN UNDERSTANDING OF THE DEVELOPMENTAL BIOLOGY HAVE ALLOWED US TO RECONSTRUCT THE SEQUENCE OF EVOLUTION OF THE ASTEROZOANS (WITH A COMPREHENSIVE PHYLOGENETIC FRAMEWORK). WE EXPLORE THE EARLIEST COMMON ANCESTORS THE SOMASTEROIDS AND THEIR CAMBRIAN ECHINODERM RELATIVES, INCLUDING A FOSSIL, WHICH IS THE EARLIEST STARFISH LIKE ANIMAL SO FAR RECORDED IN THE FOSSIL RECORD. WE THEN FOLLOW THESE EXCEPTIONAL FOSSILS THROUGH THE ORDOVICIAN AS TRUE OPHIUROIDS AND ASTEROIDS APPEAR AND SHOW HOW THEY RAPIDLY DIVERSIFIED DURING THE BIOTIC REVOLUTION WE CALL THE GREAT ORDOVICIAN BIODIVERSIFICATION EVENT. WE DEMONSTRATE THAT THESE ANIMALS SURVIVED UNTIL THE PERMIAN, WITH SOME OF THEIR DESCENDANTS STILL FOUND IN THE OCEANS TODAY.
