{'catastrophic earthquake': [0, 1, 0, 0], 'acceleration': [0, 0, 2, 8], 'gravity': [0, 0, 0, 6], 'sec2': [0, 1, 0, 0]}

The acceleration due to gravity is a constant value for every object on earth, it doesn`t change due to the occurrence of earthquakes. The value is approximately 980 cm/sec².

In option 4, the value is given as 980 cm/sec² which is the correct measure for acceleration due to gravity on earth.

Option 1, 2, and 3(550 cm/sec², 750 cm/sec², and 950 cm/sec²) are not correct because the acceleration due to gravity isn`t dependent on the occurrence of earthquakes, and it isn`t as low as these values on the Earth`s surface.

The severity of an earthquake is calculated using other methods, such as the Richter scale and Mercalli scale, not by the acceleration due to gravity. Therefore, the argument that the values could be different in the context of a catastrophic earthquake is not valid here.
