No real "heads-up" needed. This 'swarm' is very typical of the area and you can pull up the USGS (or CalPoly, others) map on any given day and see
roughly the same thing. The fault zone in this area is quite active and desirable as it means the strike-slip plate boundary is behaving exactly as
it should and as expected.
Actually, the map you reference is relatively 'quiet' as earthquake groupings go. Several hundred small earthquakes per day, nearly all of which are
with focal points too far down to be felt, is more the 'norm' in the Hemet area.
Now - if things get MORE quiet than what you have indicated - then we may have something to be concerned about. Like two cheese graters rubbing each
other in opposite directions, if the Pacific Plate (southbound) and the North American Plate (northbound) get hung up on each other - THEN I would
begin to worry and expect a "Big One" to follow soon thereafter.
This 'swarm' however is perfectly normal -and a good thing to see...
