The post Quake data: Unconfirmed quake reported: 1.1 mi southeast of Chinatown, San Francisco County, California, USA, 16 Might 2021 09:38 GMT / VolcanoDiscovery appeared first on Los Gatos News And Events.

Although our monitoring service initially determined network activity typical of an earthquake, there was no confirmation from a national or international seismological agency. Because of this, it is highly unlikely that it was caused by an earthquake.

If you felt this quake (or if you were near the epicenter) please share your experience with us and submit a short “I Felt It” report! Other users would love to hear about it!
Even if you did NOT feel the quake even though you were in the area, please Report it! Your contribution is also useful for earthquake research and for earthquake hazard analysis and mitigation. You can use your device’s location or the map to tell you where you were during the earthquake. Many Thanks!

Data for the same earthquake reported by different authorities

Info: The more agencies report on the same quake and publish similar data, the more confidence you can have in the data. It usually takes up to a few hours for the earthquake parameters to be calculated with near optimal accuracy.

It is assumed that this record was not from an actual earthquake. This may be due to some other (unknown) event that causes tremors, e.g. B. Explosions, sonic booms, weather or other human or natural causes. Even officially reported earthquakes are sometimes removed again later when seismic signals that were initially processed automatically are later manually reinterpreted so that they do not originate from real earthquakes.

This can happen when initial automatic calculations return an earthquake, but turn out to be incorrect in subsequent (manual) revision.
