Was it felt in Riobamba?
The largest nearby quake this month, M4.2 at 98 km, may have been felt lightly in Riobamba by a rough rule of thumb (an M3 is typically noticed within a few tens of km, an M5 up to a few hundred km; local ground and building type matter a lot).
None of the quakes listed has "Did You Feel It?" reports in the USGS feed, which usually means shaking at the surface was weak or the area has few reporters.
If you felt shaking, you can report it to USGS; reports refine the intensity map within minutes.
Tsunami warning status
None of the earthquakes near Riobamba in the past year carried the USGS tsunami flag, which USGS sets for large quakes in oceanic regions where the tsunami warning centres issue messages.
Official tsunami warnings come from the NOAA tsunami warning centres (tsunami.gov) and national agencies; follow local authorities if you are on a coast after strong shaking.
Earthquakes around the world today
Worldwide, USGS listed 154 earthquakes of M1+ in the last 24 hours; the largest was M6.5 Bonin Islands, Japan region.
USGS lists every magnitude in the United States but outside it coverage is complete only from about M4–4.5, so smaller local quakes reported by national agencies may be missing. Magnitudes and locations are revised for hours after an event.
