Popocatepetl is stratovolcano in the central volcanic belt of Mexico. On Dec. 6, 1997 Popocatepetl showed noticeable activity. It erupted large clouds of ash and volcanic rocks. The ash rose over 1/2 a mile into the air. Ash fell on towns over 60 miles away.

The dome at Popocatepetl continues to grow at a high rate and is at least 150 ft. tall. On October 28 an explosive eruption at Popocatepetl took place. The large eruption sent ash to the west and produced a ash cloud that climbed to a height of 27,000 ft.

Observations of the summit crater showed a new vent had formed in the lava dome that was active from March to July, 1996. Fumaroles continue to release gas from the crater and the lava dome. Scientists had believed that new magma was being added to a large magma chamber beneath the volcano.

On June 19, 1997 Popocatepetl threw ash and steam over one mile high. The activity lasted for three minutes. Popocatapetl threw ash 7.5 miles into the air on June 30 during its largest eruption since 1925. Lava was also thrown 1500 feet into the air. This event led to the first ash fall in Mexico city in 70 years. Mexico city is located 45 miles from the volcano.

On August 26, 1997 Popocatapetl erupted ash to about 2500 ft. into the air. They were not considered dangerous eruptions.
