Strong eruptions at Mexico's Popocatepetl volcano, ash to 11.3 km (37 000 feet) a.s.l.

Strong eruptions took place at Mexico's Popocatepetl volcano at 14:19 and 14:47 UTC (09:19 and 09:47 UTC) on June 3, 2019, producing an ash column up 11.3 km (37 000 feet) above sea level. The Alert Level remains at Yellow, Phase Two (middle level on a three-color scale).

The eruption was seen in satellite imagery moving in multiple directions, the Washington VAAC reported. The highest volcanic ash was seen rising up to 11.3 km (37 000 feet) a.s.l., moving NW with some volcanic ash fanning out and heading NNW, it reported 16:37 UTC.

Volcanic ash to 9.7 km (32 000 feet) a.s.l. continues moving west with a gradual turn toward the WNW-NW, the center said at 19:48 UTC.

The monitoring systems of the Popocatépetl volcano registered 37 exhalations in 24 hours to 15:00 UTC (10:00 LT) on June 3, CENAPRED reported.

Due to the dense cloudiness, they were not always visible, although they were accompanied by water vapor, gas and light amounts of ash.

The first explosion threw ballistic material at a distance of 2 km (1.2 miles) on the southern sector. 

Additionally, 194 minutes of tremor were recorded.

Ashfall was expected in the municipalities of Ecatzingo and Atlautla, State of Mexico; Ayala, Cuautla, Jantetelco, Jonacatepec, Ocuituco, Temoac, Tetela, Yecapixtla and Zacualpan, State of Morelos; and Acteopan, Atzizihuacan, Cohuean and Tochimilco, State of Puebla. 

After a series of strong eruptions, CENAPRED raised the Alert Level to Yellow, Phase Three (the middle level on a three-color scale) on March 28 and lowered it back to Yellow, Phase Two on May 7.
