Earthquake time

Is the earthquake time wrong?

Earthqakes are recorded in Universal Time Coordinated (UTC), very similar to the Prime Meredian time (Greenwich).
The italian local time (IT) is UTC+1 hour (+2 during Daylight saving time, DST).
If you want to find an earthquake you have felt in Italy around 8:00 am, look around 7:00 UTC (or 6:00 UTC, during DST).


My quake is missing! This night I have clearly felt a few shocks, but they are not reported on ISIDe. Why?

Have you looked for the UTC time (see previous question)? Fine!
It is very unlikely that National Network seismometers miss earthquakes felt by humans. Nevertheless, if the quake is very weak, it can be difficult to locate and eventually might be slightly misplaced.
Enlarge a little your search area to check if it has been located farther than you thought.
