Richter's book is still very good, but it is also outdated.  The  
copyright on the book I have is 1958, 51 years ago.  Seismology is an  
evolving science and has changed greatly since 1958.

One book to consider is WHOLE EARTH GEOPHYSICS - An Introductory  
Textbook for Geologists & Geophysicists by Robert J Lillie.  This is a  
college level book, and lays an excellent foundation for seismology.   
The math is simplified algebra, and no calculus.  Seismology is a  
subset of geophysics, and it gives a good overview on the subject.

Another good book to consider is THE MECHANICS OF EARTHQUAKES AND  
FAULTING by Christopher H. Scholz.   Lots of text, and very little  
math.  The author starts out with the brittle fracture of rocks, and  
moves into faulting and earthquakes.

Still another set of books to consider is THE SEISMIC WAVE FIELD VOL  
1: Introduction and Theoretical Development;  Vol 2: Interpretation of  
Seismogram on Regional and Global Scales.  Volume 1 has much more math  
than Volume 2.

The standard textbook used at several universities is AN INTRODUCTION  
TO SEISMOLOGY, EARTHQUAKES, AND EARTH STRUCTURE by Seth Stein and  
Michael Wysession.  The math is moderate to high, but it is probably  
the most through book I have in my collection.

Books to AVOID

PRINCIPLES OF SEISMOLOGY by Agustin Udias - Lots and lots of math.......

SEISMIC WAVES AND SOURCES by Ari Ben-Menahem and Sarva Jit Singh -  
VERY HEAVY with math.
