Agency solutions
The same earthquake as measured independently by each agency. Values are never averaged or rewritten.

Why the agencies differ
Differences of a few tenths of a magnitude unit and tens of kilometres are normal and expected. Each agency uses a different set of seismic stations, a different velocity model for the Earth's interior, and sometimes a different magnitude scale altogether. None of them is “wrong”; they are independent measurements of the same event.
Prakruti groups solutions only when they agree closely in both time and location, and shows the preferred solution — favouring an analyst-reviewed moment magnitude where one exists — while keeping every other solution visible above.
Felt reports
Felt reports are crowd-sourced and reflect where people had internet access and chose to respond. They are not a complete map of who felt the earthquake.
