Does the timing of a tsunami affect its impact?

As soon as a tsunami approaches the coast, its speed decreases considerably. This is because the speed of a tsunami depends on the depth of the water; the lesser the depth of the water, the lesser the speed of an approaching tsunami. However, there is no change in the overall impact of a tsunami.

the correct answer is c

true. earthquakes are felt whenever there is a slip around a fault in the rocks below the earth. this reorientation of faults create sesmic waves and is known as earthquake, the severity of which is measured in richter scale. these are more prominent in hilly regions as the rocks usually form faults to balance the pressures on it.
