According to the Cape Verde National Institute of Meteorology and Geophysics (INMG), seismicity at Brava increased on 30 October and remained elevated. A M 3.6 earthquake was recorded at 1819 on 30 October and was followed by eight more events of similar magnitudes that were felt by residents. A M 4.8 was recorded at 2100 and was followed by a 48-hour-long seismic swarm mostly consisting of low-magnitude events that were unable to be located. The Alert Level was raised to 2 (the second level on a five-level scale) on 30 October.

The rate of seismicity was variable, with two events every 1-10 minutes during 30 October-1 November. Most of the events were located at depths of 3-4 km; the hypocenters were initially located in the Praia de Águada area but then they migrated towards the center of the island. Continuous harmonic tremor emerged on 9 November and was interpreted as indicating the movement of magmatic gases. On 15 November seismicity increased and was characterized by more intense periods of volcanic tremor, long-period events, and “burst” events defined as identical events separated by a few seconds. In addition, residents began to feel earthquakes more often. The Alert Level was raised to 3. Three earthquakes all with magnitudes greater than three occurred during 18-19 November, and harmonic tremor again intensified on 19 November.

According to the Universidade de Cabo Verde in a report posted on 4 August, Instituto Nacional da Meteorologia e Geofísica (INMG) recorded increased seismicity at Brava beginning at dawn on 2 August. In response authorities evacuated 300 people, based on a news report. Earthquakes were felt by residents during 3-4 August. Scientists and technicians from the Universidade de Cabo Verde (UniCV), Instituto Vulcanológico das Canárias (INVOLCAN), and Serviço Nacional da Protecção Civil (SNPC) began monitoring carbon dioxide emissions though found nothing unusual during 4-7 August.
