On Wednesday, a very rude 6.2 earthquake struck in the Marmara Sea, according to the United States Geological Survey.
The Temblor occurred at 12:49 p.m., Eastern Europe time at around 25 miles southwest of Istanbul, according to the agency data.
While seismologists examine the available data, they can revise the indicated scale of the earthquake. Additional information collected on the earthquake can also encourage scientists to the USGS to update the Shake-Severity card.
Replicas in the region
A replica is generally a smaller earthquake that follows a larger one in the same general area. Replicas are generally minor adjustments along the part of a flaw that slipped at the time of the initial earthquake.
Quakes and replicas within 100 miles
Replicas can occur for days, weeks or even years after the first earthquake. These events can be of an equal or more important scale for the initial earthquake, and they can continue to affect the already damaged locations.
When earthquakes and aftershocks have occurred
Source: United States Geological Survey | Notes: the categories of tremors are based on the Modified mercalli intensity ladder. When repair data is available, the corresponding cards and graphics include earthquakes within 100 miles and seven days depending on the initial earthquake. All times above are the time of Eastern Europe. Shake data is from Wednesday April 23 at 6 h 01 Eastern. Replica data is from Wednesday April 23 at 12:04 p.m. Eastern.
