Answer 1

The first earthquake was 1.32 times greater than the second, and the same as the third.

Since Cotabato was struck by a series of quakes from June 1 to 3, 2013, and the first was a 5.7 earthquake on June 1, followed by 15 aftershocks, and a 4.3 and a 5.7 quake were recorded on June 2 and 3 respectively, for To determine how much more powerful was the first earthquake than the proceeding ones, the following calculation should be performed:

• 4.3 = 1
• 5.7 = X
• 5.7 / 4.3 = X
• 1.32 = X

Therefore, the first earthquake was 1.32 times greater than the second, and the same as the third.
