According to the Direction Générale de la Sécurité Civile – Comores, the Observatoire Volcanologique du Karthala (OVK) reported that a significant increase in the number of small earthquakes beneath Karthala's W flank began to be detected on 15 July. The abnormal activity persisted, so on 16 August the Alert Level was raised to Yellow (the lowest level on a three-level scale) and residents were asked to limit activities on and around the volcano. On 5 September OVK recommended that the Alert Level remain at Yellow.
