On the richter scale, the magnitude r of an earthquake of intensityi is
r = log10 i/io
where lo is a reference intensity. at 7: 23am on march 19, 2003, an earthquake measuring 3.0 on the richter scale occurred near the town of nephi. an earthquake of that magnitude is often felt, but rarely causes damage. by comparison, the earthquake that struck san francisco in 1906 measured 8.25 on the richter scale. it was as intensive as the nephi earthquake.
