Abstract
Long-period seismic event of 11.11.2018 was studied; this event is connected with the birth of a volcano near Mayotte island (Comoro islands archipelago). Using seismic records from the networks of stations of Institute of Geophysical Research, a seismic bulletin was created; kinematic and dynamic parameters of this event were studied; its localization was identified and regional magnitude on surface MLH waves was calculated. Seismic records of analog events on 02.09.2018 were found and researched. Recommendations for analysts on processing and classification of long-period monochrome tremors were proposed.
