how will you describe the surrounding when an earthquake strikes with greater magnitude and intensity

Idont might be experiment it or search it

The apparent magnitude of a celestial object, such as a star or galaxy, is the brightness measured by an observer at a specific distance from the object. the smaller the distance between the observer and object, the greater the apparent brightness.

since there are no given stars in the question i would give you a reference on the brightest to dimmest stars as observed by the astronomers.
