Simon Klemperer

Dear Prof. Liner:

I just wanted to take a break from updating my lectures on migration to say how much I am enjoying “Elements” to teach my Reflection Seismology class. Beautifully clear, with an original take on numerous concepts and very different in philosophical approach from a more “conventional” text like Sheriff & Geldart.

But I had to go online to find your contact info, and because I have a butterfly mind I also now have a .pdf of Greek Seismology and encourage you, should there be a v. 2.1, to correct the typo on page 6: “There was also earlier experimental work by Hook, Galileo and others” to give Hooke his due terminal e (he does indeed feature in my lectures for “ut tensio, sic vis”)

And finally, I am intrigued by Spice: is it available for academics to play with? One of my students is making seismic-stratigraphic interpretations, and I would be fascinated to see whether anything new came out of the data.

Dear Simon,

Thank you for the very kind note. It is not often that one gets such a complimentary email. So glad you are enjoying the Elements book, I assume you are reading the 3rd edition. It is much improved from the 2nd edition.

I would love to make the correction you mention to the Earthquake book. But, alas, the source file is in word 6 or word 95 (which may be the same thing), and current Word versions will not open it. So we are stuck with the PDF only.

Yes, spice will be available in the next release of seismic unix. The source file is attached. If you are familiar with SU, adding this to your install should not be too much trouble. A typical processing flow would go like this:

   succwt < in_su_data   fmax=100 noct=5 nv=10 \
   | suspice  seth=1 amax=35 amin=1,5,10 ta=0,2,4 > out_spice_data

Hope you find spice useful. I have found it takes very good quality data before spice works well. But when it works, it is remarkable.

Best regards,


ps. If you don't mind, I'll post your letter and my response to my seismos blog.
