On the Origin of Orphan Tremors & Intraplate Seismicity in Western Africa

Structural investigation of Zungeru-Kalangai fault zone and its environ, Nigeria using aeromagnetic and remote sensing data

“…Studies have also shown that some tremors experienced in Nigeria might be associated with the dynamics of the oceanic fracture zones (e.g. Akpan and Yakubu, 2010 ; Afegbua et al., 2011 ; Shiwua, 2013 ; Tsalha et al., 2015; Thomas et al., 2020 ; Olugboji et al., 2021 ). These studies show that the epicentre of a reported occurrence of an earth tremor in Lupma, Niger State lies along with the northward extension of the Zungeru-Kalangai fault zone.…”
