WebAn earthquake's intensity is determined by observing its effects at a particular place on the Earth's surface. Intensity depends on the earthquake's magnitude, the distance from the epicenter, and local geology. These scales are based on reports of people awakening, felt movements, sounds, and visible effects on structures and landscapes. WebEarthquake Magnitude Scales The severity of an earthquake is generally proportional to the amount of seismic energy it releases. Seismologists use a Magnitude scale to …
