A 4.7 magnitude earthquake is considered a moderate earthquake with the potential to cause severe damage, especially to less stable buildings. It corresponds approximately to an intensity level VII on the intensity scale, where the earthquake is felt strongly, people may be alarmed and lose their balance, and there is a likelihood of severe damage to structures, including possible collapse of less stable buildings. Such an earthquake may be felt over a wide area and can cause damage from falling objects inside buildings.

In terms of energy release, a 4.7 magnitude earthquake releases significantly less energy than larger earthquakes but still enough to be felt by most people, causing hanging objects to swing, and rattling dishes and windows. Damage is generally minor unless buildings are poorly constructed.

For example, in a recent 4.7 magnitude earthquake that struck British Columbia in 2025, inspections found no structural damage to key infrastructure in the region, highlighting that modern buildings adhering to updated seismic codes may withstand such earthquakes without major harm.

In summary, a 4.7 earthquake is strong enough to shake buildings noticeably and potentially cause damage to vulnerable structures but is unlikely to cause widespread destruction in well-prepared areas.
