Understanding Earthquake Magnitudes
Earthquakes are classified based on their magnitude as follows:
- Micro: less than 2.0
- Very small: 2.0-2.9
- Small: 3.0-3.9
- Light: 4.0-4.9
- Moderate: 5.0-5.9
- Strong: 6.0-6.9
- Major: 7.0-7.9
- Great: 8.0-8.9
- Exceptional: 9.0-9.9
- Extreme: above 10
The Modified Mercalli Scale measures the "degrees of intensity and respective description" of an earthquake.
What to Expect with Intensity III and IV
With an intensity of III, considered weak, the tremor is felt indoors and hanging objects sway, resembling a "vibration similar to that caused by heavy vehicles passing by," as noted by the IPMA on their website.
An intensity of IV (moderate) and V (strong) means that the vibration is similar to that caused by passing vehicles, parked cars shake, windows and doors rattle, and it can be felt outside the home.
