Geology: the (almost) musical

Whilst reading through the songrelated submissions to the current, geo-arty edition of the Accretionary Wedge, my mind was cast back to my dim and distant undergrad days, when no field trip was complete without sem-drunken final evening entertainments, and the highlight was usually a trio of our years’ finest wits (not me) getting together and summarising our excursion through the medium of modern pop music. The following was composed during a tectonics field trip to Greece; it’s possible that you had to be there (and possibly also pickled in retsina) to find this funny, but I’ll give some background after the fold.

(to the tune of Pulp’s Common People)

We came to Greece we had a thirst for knowledge.
We studied geology at a Cambridge college;
that’s where I
caught James’ eye.
He told me about vertical fissures.
We said, “In that case all faults must be vertical”.
He said, “No!”
and then in thirty seconds time, we said:

We want to know about normal faulting;
we want to know whatever normal faults do;
we want to sleep under a normal fault;
we want to sleep under a normal fault – like you.

So he took us to a rubbish dump.
We don’t know why but he had to start it somewhere –
so he started it there.
He said, “Pretend you’ve got no compass-clino”
We said, “In that case we can’t measure any dips and strikes”
So we went home.

Are you sure…
You want to know about normal faulting;
You want to know whatever normal faults do;
You want to sleep under a normal fault;
You want to sleep under a normal fault – like me?
But we didn’t understand,
we called it fault breccia and raised our hands.

Drink retsina,
draw a log,
grow your goat and look at rocks,
smoke cigars and play the fool,
tell the kids “Go back to school!”.
But you’ll never get it right
‘cos though you think you’ve seen the light,
you’ll draw your faults as vertical,
and if you called Doctor Jackson you could stop it all- yeah!

You’ll never know about normal faulting,
you’ll never know what normal faults do;
you’ll never fail like a normal fault,
you’ll never bust like normal faults do.

Like Rachel Flecker at the outcrop,
she will quiz you and never warn you.
Look out! She’ll draw your knowledge out.
Cos demonstrators hate the students
– especially ones who think it’s all such a laugh,
and that gyros stains from Greece
will come out in the bath.
And you’ll never understand
how the big guys control the land.
You’re amazed that they exist,
and their slip’s so big that you can only wonder why…

You’ll never know about normal faulting,
you’ll never know what normal faults do;
you’ll never fail like a normal fault,
you’ll never bust like normal faults do.
We wanna know about normal faulting like you,
wanna know about normal faulting like you,
wanna know about normal faulting like you…
la la la la la la la,
la la la la la la la,
la la la la la la la – oh yeah!

The geological map is a work of art in itself.

The power of great art often lies in the way that it can make us see the familiar or mundane in entirely new ways. Which is why when asked to consider works of geological art, one piece springs to my mind above all others:

Was the Sichaun earthquake ‘boosted’ by reservoir loading?

There’s been a lot of discussion about the effects of the Sichaun earthquake, such as the Tangjiashan ‘quake lake’ which has now been drained in a safe, if not strictly controlled, manner (the BBC also has some cool photos). But aside from Kim’s excellent summary of the tectonic context, we haven’t talked much about the earthquake itself. According to this article in the Washington Post, although the Sichaun region was by no means seismically inactive, no-one was expecting such a large earthquake there:

many scientists were caught by surprise by the magnitude of the China earthquake, estimated at 7.9 by U.S. scientists. Sichuan province has a history of earthquakes, but none so devastating. It was not near the top of anyone’s list of the most likely locations for a great quake. The data from satellites, which can track the motion of vast plates of the Earth’s crust, suggested a relatively moderate amount of strain building up in the rugged mountain front along the edge of the Sichuan basin.

The Geoblogosphere

For the benefit of anyone who is new to the geoblogosphere, below is a list of the currently active (defined as ‘posted something in the last 2 or 3 months’) geology and earth science related blogs that are picked up by the feed you see on the left of this page:


I make that 45, and I’m probably missing some (if you can see an omission, please enlighten me in the comments). Our merry band has certainly grown in the last few months, and will hopefully continue to do so – it’s nice to see how wonderfully crowded my little corner of the internet has become.

Latest on the Tangjiashan ‘quake lake’

For those wanting to hear the latest news about the efforts to drain the Tangjiashan ‘quake lake’ which formed after the Sichaun earthquake, Dave Petley has written a number of posts discussing how the situation has developed over the last few days. It seems that water began to flow through a drainage channel dug by the Chinese Army on Saturday, but it’s too early to say whether this action is successfully going to stablilise or lower the lake levels.
