SELECT T1.Event_ID, T1.event_details FROM EVENTS AS T1 JOIN Participants_in_Events AS T2 ON T1.Event_ID = T2.Event_ID GROUP BY T1.Event_ID HAVING COUNT(*) > 1
SELECT "T1"."Event_ID", "T1"."event_details" FROM "EVENTS" "T1" JOIN "Participants_in_Events" "T2" ON "T1"."Event_ID" = "T2"."Event_ID" GROUP BY "T1"."Event_ID" HAVING COUNT(*) > 1
