In the last 24 hours the monitoring system of Popocatépetl volcano registered 83 long period earthquakes (LPs) . Also were registered 420 minutes of harmonic tremor of low amplitude.
At night webcam images shows some glow sources within the crater .



At the time of this report we cannot see the volcano due to weather conditions .
CENAPRED emphasizes that people SHOULD NOT go near the volcano, especially near the crater, due to the hazard caused by ballistic fragments .
This type of activity is included within the scenarios Volcanic Traffic Light Yellow Phase 2.

Sangay , Ecuador :

2.005°S, 78.341°W
Elevation 5286 m

IG reported that at the beginning of March Sangay began a new phase of activity which continued through at least 12 May without significant changes. The number of tremor events and long-period earthquakes were slightly higher in March as compared to the number recorded in April and May, and the number of explosions was slightly higher in April and May. Surficial activity was characterized by frequent ash emissions generated by explosive activity. Thermal anomalies on the flanks were also detected, mostly within 5 km of the summit crater, which possibly corresponded to short-range pyroclastic flows and lava flows. No abnormal sulfur dioxide emission were detected.



The isolated Sangay volcano, located east of the Andean crest, is the southernmost of Ecuador’s volcanoes, and its most active. The dominantly andesitic volcano has been in frequent eruption for the past several centuries. The steep-sided, 5230-m-high glacier-covered volcano grew within horseshoe-shaped calderas of two previous edifices, which were destroyed by collapse to the east, producing large debris avalanches that reached the Amazonian lowlands. The modern edifice dates back to at least 14,000 years ago. It towers above the tropical jungle on the east side; on the other sides flat plains of ash have been sculpted by heavy rains into steep-walled canyons up to 600 m deep. The earliest report of a historical eruption was in 1628. More or less continuous eruptions were reported from 1728 until 1916, and again from 1934 to the present. The almost constant activity has caused frequent changes to the morphology of the summit crater complex.

The tremor continues with a large amplitude , not vary much, and is accompanied by a passive and continuous emission of gas and ash with moderate volumes. Between 9 am and 17 pm today, increases were recorded in the emission of ash and eruptive activity over short time intervals. The main events took place from 11h00 to 11h50 , between 12h 20 am and 13h20 , and from 15h00 p.m. to 15h30 p.m. .
