GEOLOGY

Detailed explanation-1: -In 1943 a cinder cone started growing on a farm near the village of Parícutin in Mexico. Explosive eruptions caused by gas rapidly expanding and escaping from molten lava formed cinders that fell back around the vent, building up the cone to a height of 1, 200 feet.

Detailed explanation-2: -Parícutin (or Volcán de Parícutin, also accented Paricutín) is a cinder cone volcano located in the Mexican state of Michoacán, near the city of Uruapan and about 322 kilometers (200 mi) west of Mexico City.

Detailed explanation-3: -In contrast, the eruptive activity of Parícutin Volcano in 1947 demonstrated a “Vulcanian"-type eruption, in which a dense cloud of ash-laden gas explodes from the crater and rises high above the peak. Steaming ash forms a whitish cloud near the upper level of the cone.

Detailed explanation-4: -In 1943, thick, sticky lava, driven by large volumes of gas, exploded from Paricutin’s vents: material that was blasted into the air to cool and solidify. Much of it fell back around the vent, forming a cone-shaped mountain of cinders.

Detailed explanation-5: -The eruptions of most cinder cones are usually mildly to moderately explosive (Strombolian to Vulcanian), but rarely can have Sub-Plinian activity. Their usually low explosivity is due to the low viscosity and low volatile content of magma.
