Ceboruco

Ceboruco, a dacitic stratovolcano in Nayarit, Mexico, preserves more than a millennium of volcanic history in its lava fields, domes, and nested craters. Its most important known event was the Jala Plinian eruption around 930 AD, a VEI 6 explosion that expelled about 11 cubic kilometres of tephra, reshaped the summit, and formed a broad caldera. Around 1100 AD, the Coapales eruption created a smaller inner crater when the Dos Equis lava dome collapsed. Additional lava flows followed before 1521, and later activity remained mostly within the calderas until a major eruption from 1870 to 1875. Ceboruco remains an important active volcanic system and record of repeated rebuilding by explosive eruptions and lava extrusion.
