ERRATA FOR TECilNICAL REPORT 79-2 APRIL-JUNE 1978 SEISMICITY NEAR 'IllE V. C. SUMMER NUCLEAR STATION The following corrections and additions are to be made to TR 79-2.

Report Summary, paragraph 1, line 9 "3.8" should be changed to "2.8".

Page 8, tabic 5 The distance for K3 = .282 should be "R 2 4.8 km" instead of R 14.8 km.

Pag'e 20, paragraph 1, line 3 The following sentence should be added between " period" and " April".

"The number of unlocatable events observed at Site 1 during this report period increased dramatically, relative to previously observed rates, as a result of the doubling of the site gain (on 27 March 1978) and reduced traffic noise."

Page 20, paragraph 1, line 7 Place a "." after " events" and then insert the following text.

" Site 3 observed only about 95% of the events during April as it had during March. In May and June, borever, it only observed about 90% of the events. The high rate for Site 2 is unusual because it observed only 93% of the locatable events"

Page 26, figure 8 The linear recurrence curve and equation fit to the cumulative data should be added to the figure.

The equation is " log N c= 4.24 -1.40 DMAG".
