Popocatepetl , Mexico :

10 June 11.00 (10 June, 16.00 GMT)

Over the past 24 hours, by monitoring systems of the Popocatepetl volcano, 183 low-intensity exhalations, accompanied by volcanic ash and gas have been identified. Because the weather conditions were cloudy it was not possible to observe all emissions.

During this report, steam and gas emission with small amounts of volcanic ash is observed to the south.

CENAPRED asks not to approach the volcano and in particular the crater.

The semaphore of volcanic alert of Popocatepetl Volcano is located in Amarillo Phase 2.

Constant rainfall has been present in the Fuego volcano area since 11:50 am and again leads to the descent of a strong lahar through Canyon Ceniza.
These lahares can reach an approximate size of 15 to 18 meters wide and a height of about 1 to 3 meters. On its course it carries materials ranging from fine sediments (mainly ashes), blocks up to 1 meter in diameter as well as trees and vegetation.
Because of the constant rain in the area, these events may also be present in the rivers Mineral, Santa Teresa / Seca, El Jute and Las Lajas rivers, so if the people pass through these areas, take precautions .

 

Activity:
Presence of continuous white outgassing fumaroles, reaching a height of about 4,400 meters (14,435 ft), spreading westward. Approximately 27 explosions were reported, of which 20 were moderate and 2 were strong, emitting columns of gray ash at a height of 4.400 to 4.800 meters (4.435 to 15.748 feet) spreading 12 km to the West, Northwest and North. Some explosions generated moderate to strong rumblings. The explosions produced moderate to severe avalanches to the Ceniza, Taniluyá, Santa Teresa and Trinidad gullies. The projections reached the vegetation.
