How fast do volcanoes grow?

 Q:   Ask a Question about How fast do volcanoes grow?       
How fast do volcanoes grow? Unlike most geological happenings, the growth of a volcano can be very rapid. In 1943, a farmer in Mexico noticed smoke coming from a crack in the ground in his cornfield. Lava began to ooze out, and six days later it had piled up into a volcanic cone 150 m high. By the end of the year the cone had grown to 450 m.

The eruption finally stopped in 1952, when the volcano Paricutin had reached a height of 2,808 m above sea level. The volcano had buried two whole villages.

Masses of dust and rocks hurled out from an active volcano fall back and cause a volcanic cone to develop.

Lava may escape from the crater in the centre or find its way out through vents in the side of the volcano, and the flowing lava solidifies as it cools in the air.
