Σεισμική δόνηση μεγέθους 4.3 βαθμών στην κλίμακα Ρίχτερτην εκδηλώθηκε τη Δευτέρα 31 Μαΐου 2021 και ώρα 09:23. Ο σεισμός είχε επίκεντρο το θαλάσσιο χώρο 18 χιλιόμετρα βορειοδυτικά της Μόρφου και εστιακό βάθος 50 χιλιόμετρα. Ο σεισμός έγινε αισθητός σε μεγάλο μέρος του νησιού λόγω του μεγάλου εστιακού βάθους του, και ιδιαίτερα στις επαρχίες Πάφου, Λεμεσού και Λευκωσίας.
