Other Geological Events

Other geological events, such as meteor sightings, and fireballs are minor occurrences of an unpredictable nature with no damage associated with them. Of greater impact was a sinkhole at St. David's in 1985 that collapsed a driveway. The sinkhole was about 2 m diameter and 6 to 7 m deep.

Sinkholes are funnel-shaped depressions, or sinks, in the ground surface, commonly tens of metres in diameter.

Sinkholes are a hazard on the west coast of the island, although their distribution is geologically constrained to the southern St. George's Bay and Codroy Valley areas. Incidences of other geological events in Newfoundland and Labrador are shown on the map below and in the accompanying table.
