La Grille

The basaltic La Grille volcano also differs from Karthala in its abundance of pyroclastic cones up to 800 m (2,625 ft) in height.

Recent lava flows, some possibly as young as a few hundred years, have reached the sea from fissures on the lower western, northern, and eastern flanks.

La Grille appears as a mountain range running from north to south, reaching a slag height of 800 m (2,625 ft) meters on average, and covered in stratovolcano cones,[2] giving the volcano a maximum altitude of 1,087 m (3,566 ft) meters.

Different eruptive vents are located along the fissures that run along the volcano from north to south, parallel to the ridge of the mountain, and other cracks along the coast.

Lava basalt sometimes escapes from these eruptive vents, sometimes reaching the sea to the east, north and west sides of the volcano.
