This Newsletter fills an important gap in the efforts to make earthquake warnings a reality. It emerged from the amateur radio community where people have been picking up odd signals for many years. Of particular value, is the sharing of many techniques and instruments being used in basements and garages all over California and into the Midwest. It is now possible for high school and junior high students to set up their own monitoring stations. Tied together by computer, these kids will have the potential to play a major role before "THE BIG ONE" hits. GEO-MONITOR, edited by Vince Migliore, is based in Santa Clara, California.
