List of earthquakes in Iceland

From Wikipedia, the free encyclopedia

Map
Map of notable earthquakes in Iceland since 1900 numbered from most recent.

Some notable earthquakes in Iceland have been during earthquake swarms with several earthquakes having very similar magnitude and contributing to human injury, death and/or property damage. Accordingly the largest earthquake may be shown on this page rather than ones that also contributed to the notability. Notable earthquakes in Iceland tend to be close to population centres and therefore do not reflect the full distribution of the high local seismic activity. This distribution includes the transform faults in the South Iceland Seismic Zone and Tjörnes Fracture Zone, as well as activity in volcanic rift zones.[1]

Note: The inclusion criteria for adding events are based on WikiProject Earthquakes' notability guideline that was developed for stand alone articles. The principles described also apply to lists. In summary, only damaging, injurious, or deadly events should be recorded. A compilation exists,[16] for details of Icelandic earthquakes up to 2014 as some have been without significant damage, even if high magnitude events.
