Ash fall impact on vegetation: a remote sensing approach of the Oldoinyo Lengai 2007–08 eruption

“…a: Shaded relief map based on the SRTM Digital Elevation Model highlighting main volcanoes and craters; (b) Land cover map of the study area based on the FAO classification scheme (FAO 1998). Red lines highlight the approximated isopach lines of the 2007-08 ash layers inferred by Sherrod et al (2013). The full triangle marks the location of Oldoinyo Lengai West, the vegetation in the rift and above the rift escarpment is characterized by open grasslands to shrublands with scattered trees, varying with topography and rainfall distribution ( Fig.…”

“…A preliminary isopach map of the 2007-08 ash fallout was produced by Sherrod et al (Sherrod et al 2013), constraining a 5-10 cm isopach line, and partially constraining the limit of a 1-5 cm thickness isopach line (Fig. 1b).…”

Incommensurately modulated twin structure of nyerereite Na1.64K0.36Ca(CO3)2

“…At present, it is the only active volcano in the world erupting extrusive carbonate lava. Oldoinyo Lengai is a young dominantly phoboliticnephelinitic volcano, which is less than 790,000 years old (Sherrod et al, 2013), formed by a complex sequence of events, including explosive eruptions of nephelinitic and phonolitic ashes and effusion of mixed assemblages of silicate and carbonate lavas. In the recent past, several major Plinian eruptions have occurred, e.g.…”

Characterizing Archaeological Assemblages from Eastern Lake Natron, Tanzania: Results of Fieldwork Conducted in the Area

“…On the southeast, the basin is bounded by the prominent Gelai shield volcano which rises gently from the shores of the lake to an altitude of ca. 2,940 m (Sherrod et al 2013). Located to the west of Lake Natron is Peninj (Penin) (Fig.…”

“…The Sonjo Faults limit the basin to the west. South of Natron lies the Engaruka sedimentary basin separated from Natron by Oldonyo Lengai (2,878 m), an active carbonatite explosive volcano that erupted as recently as 2007/2008, the Kerimasi volcano, and a horst created by oblique faults Sherrod et al 2013) before rising to the Manyara escarpment (Fig. 2).…”
