ଭୂମିକମ୍ପର ତୀବ୍ରତା ମାପ କରିବା ପାଇଁ ଏକ ପ୍ରକାର ସ୍କେଲ ବ୍ୟବହାର କରାଯାଏ । ଏହାକୁ ରିକ୍ଟର ସ୍କେଲ୍ କୁହାଯାଏ । ୧୯୩୫ ମସିହାରେ ଆମେରିକାର ଚାର୍ଲସ ଫ୍ରାଙ୍କିସ୍ ରିକ୍ଟର ଏହାକୁ ବାହାର କରିଥିଲେ । ଏହା "୦' ଠାରୁ ଆରମ୍ଭ କରି ୧୨ ପର୍ଯ୍ୟନ୍ତ ଭୂମିକମ୍ପ ତୀବ୍ରତାକୁ ମାପ କରିପାରେ । ଏଥିରେ ପ୍ରତିଟି ସଂଖ୍ୟା ତାହାର ପୂର୍ବ ସଂଖ୍ୟାଠାରୁ ୧୦ ଗୁଣ ଅଧିକ ହୋଇଥାଏ । ଏହି ସ୍କେଲରେ ଭୂମିକମ୍ପର ତୀବ୍ରତା ୨.୦ରୁ କମ୍ ହୋଇଥିଲେ ତାହାକୁ ଜାଣିହୁଏ ନାହିଁ । ମାତ୍ର ଏହି ସ୍କେଲରେ ଭୂମିକମ୍ପର ତୀବ୍ରତା ୫.୦ ବା ତା ଠାରୁ ଅଧିକ ହୋଇଥିଲେ ତାହା କ୍ଷୟକ୍ଷତି ଘଟାଇଥାଏ । ରିଚର ସ୍କେଲରେ ଭୂମିକମ୍ପର ତୀବ୍ରତା ୭.୦ ରୁ ଅଧିକ ହେଲେ ସେହି ଭୂମିକମ୍ପ ଜନିତ କ୍ଷୟ କ୍ଷତି ଅତି ଭୟାବହ ହୋଇଥାଏ ।

The following table lists the approximate energy equivalents in terms of TNT explosive force – though note that the earthquake energy is released underground rather than overground.[୧] Most energy from an earthquake is not transmitted to and through the surface; instead, it dissipates into the crust and other subsurface structures. In contrast, a small atomic bomb blast (see nuclear weapon yield) will not, it will simply cause light shaking of indoor items, since its energy is released above ground.

31.6227 to the power of 0 equals 1, 31.6227 to the power of 1 equals 31.6227 and 31.6227 to the power of 2 equals 1000. Therefore, an 8.0 on the Richter scale releases 31.6227 times more energy than a 7.0 and a 9.0 on the Richter scale releases 1000 times more energy than a 7.0. Thus,
