Eruption at a developing submarine volcano east of Mayotte continues and may contaminate Petite Terre’s Lake Dziani. The underwater volcano is the reason behind the seismo-volcanic crisis affecting the small island in the Indian Ocean since May 2018. The crisis started with earthquake swarm that continued for months causing anxiety among locals until May 2019 when a new developing volcano was confirmed.
An underwater eruption is officially underway as of July 31, 50 – 60 km (31 – 37 miles) east of Mayotte.
The seismic activity is centered at 5 to 15 km (3 to 9 miles) from Petite Terre at depths of 25 to 47 km (16 to 29 miles). It remains stationary with a high number of quakes.
544 were recorded so far from October 16, 2019, to October 31. The average seismic activity is 38 per day, with the recording of a clear recrudescence of seismic energy released.
