The strength ( magnitude )of an earthquake is determined by the depth of its origin, the height of its surface seismic waves and by the amount of fault movement that takes place is measured by a Richter Scale, which has a range from 1-14. 14 being the strongest.

Well seismic activity which is what seism is, is a measure of how deep and how wide and how strong an earthquake is. I could not find it defined directly on the web. Geographpy is not my area but go here:http://www.seismo.unr.edu/ftp/pub/papers/renoeq/renoeq.html
good luck.

SEISMIC WAVES OR EARTHQUAKES ARE MEASURED ON THE RICHTER SCALE WHEREIN EACH SUCCEEDING NUMBER IS TEN TIMES AS POWERFUL AS THE PRECEDING ONE SO THAT A MAGNITUDE OR POWER 2 QUAKE OR SEISMIC WAVE IS TEN TIMES AS POWERFUL AS A MAGNITUDE ONE AND A MAGNITUDE 4 IS 100 TIMES AS POWERFUL AS A 2 AND ETC
