Strong eruption at Popocatepetl volcano, ash to 9.8 km (32 000 feet), Mexico

A strong eruption took place at Popocatepetl volcano, Mexico at 15:40 UTC (10:40 local time) on June 14, 2019.

The volcanic ash cloud rose to an estimated height of 9.8 km (32 000 feet) above sea level, according to data provided by the Washington VAAC.

In 24 hours to 16:00 UTC on June 14, monitoring systems registered 115 exhalations, accompanied by water vapor, gas and light amounts of ash.

There were also three explosions, the first was recorded 18:22 LT on June 13, the other two were recorded 04:03 and 08:54 LT on June 14. Additionally, a volcanotectonic earthquake was recorded at 20:40 LT on June 13, with a magnitude of 1.9 and 27 minutes of tremor.

Intense degassing was observed during an overflight on June 11. However, the flight confirmed that a dome has not been formed inside the internal crater, which maintains its dimension of 350 m (1 148 feet).

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 where it remains to date.

Geological summary

Volcán Popocatépetl, whose name is the Aztec word for smoking mountain, rises 70 km (44 miles) SE of Mexico City to form North America's 2nd-highest volcano. The glacier-clad stratovolcano contains a steep-walled, 400 x 600 m (1 312 x 1 968 feet) wide crater. The generally symmetrical volcano is modified by the sharp-peaked Ventorrillo on the NW, a remnant of an earlier volcano. At least three previous major cones were destroyed by gravitational failure during the Pleistocene, producing massive debris-avalanche deposits covering broad areas to the south. The modern volcano was constructed south of the late-Pleistocene to Holocene El Fraile cone.

Three major plinian eruptions, the most recent of which took place about 800 CE, have occurred from Popocatépetl since the mid Holocene, accompanied by pyroclastic flows and voluminous lahars that swept basins below the volcano. Frequent historical eruptions, first recorded in Aztec codices, have occurred since precolumbian time. (GVP)

The FATHER is very angry with you kingdoms for what you did to his sheep and claiming his land as your own, and now you have your eyes set on Zion and his TREE of life for his people? When JUPITER grows and his children has comes to birth what will you do then?
