Cotopaxi volcano emissions reached 1 kilometer high on Monday  :

30 MAY 2016. The Geosífico Institute (IG) of the National Polytechnic School reported that this morning there have been several gas emissions and water vapor in the volcano. The height of these emissions have reached up to 1,000 meters above the crater of the volcano.
In addition, the report #151 on the state of Cotopaxi, released by the IG Monday, it was reported that the internal activity of the volcano is low, and that the columns of gas and steam going towards the west and east of the volcano.

Moderate rain yesterday, Sunday, May 29, 2016, caused a lahar that affected secondary road Agualongo Clough, in the Cotopaxi National Park. In the evening hours more rain was registered in the volcano area, but caused no damage, according to the IG.
The Cotopaxi volcano has remained active since August 2015.




The internal activity of the volcano is low.
The rains yesterday afternoon, generated two secondary lahars that have been recorded.
This morning several emissions of water vapor and gas with heights up to 1000 meters above the crater were observed.
From 13:00 (TL) yesterday until 13:00 (TL) today, 33 volcano-tectonic events (VT) and 3 events long period (LP) were recorded.

Observations of emissions and ashes:
In the morning, the volcano sector has discovered and several emissions of gases and water vapor were observed up to a height of 1000 meters above the level of the crater, with west and east directions.
At the moment the volcano is cloudy and the rain falls in the area.
Gas: The value of sulfur dioxide emissions is 906 tons / day, with 2 valid measurements.
Rain and lahars:
The rains in the volcano sector generated two secondary lahars yesterday afternoon, who filed materials on road Clough  – Agualongo.


This report contains data and observations from 13:00 hours the day before to 13:00 on the date of publication (24 hours).
In the case of an increase or a change in the behavior of the volcano, it will be published a special report.

El Hierro ( Tagoro ), Canaries :

The underwater volcano of El Hierro, named Tagoro

30 MAY 2016. The underwater volcano of El Hierro has been officially named Tagoro, a Berber word meaning circular stones or meeting place precinct and has been proposed by the Spanish Institute of Oceanography at the Hydrographic Navy, responsible for such designations.
The Hydrographic Institute of the Navy (IHM) has called officially with the name Tagoro volcano in letters numbers 618 and 61B to until Monday known as submarine volcano on the island of El Hierro, reported in a statement the IEO,

This feature of the seabed of the Canary Islands and listed on nautical charts published by the IHM itself, which has been possible thanks to the official request made by researchers at the Vulcano project, led by the Spanish Institute of Oceanography (IEO).

The underwater eruption that occurred in October 2011 to 1.8 kilometers south of the fishing town of La Restinga on the island of El Hierro generated in just 6 months, a submarine volcano 400 meters deep, whose summit main was 89 meters over the sea surface, reaching a height of 312 meters.

The base of the volcano has a sub-circular shape 738 by 950 meters and a slope of 18.4 degrees. Tagoro was mapped first by the research vessel Ramon Margalef IEO in October 2011 and since that time, researchers at the Spanish Institute of Oceanography, the Universities of Las Palmas and La Laguna and the Museum of Nature and the man of Tenerife, in collaboration with other research institutions canary, have dedicated themselves to their physico-chemical, biological and geological survey.

Popocatepetl , Mexique :

May 30 11:00 h (May 30 16:00 GMT)

In the last 24 hours the seismic records of the surveillance system at Popocatépetl volcano registered on the one hand 96 low-intensity exhalations, which produced small emissions of gas and steam . The cloudy conditions not allow observing the volcano continuously, but we observed a weak emission of steam and gas that winds carried southwesterly. Additionally, the monitoring system 68 minutes tremor of low amplitude.



Along some lapses of the night was observed slight incandescence, increasing with main exhalations .
From dawn and up to the time of this report it has been noticed that winds blow about southwest .

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.

Marum ,  Ambrym Island , Vanuatu :

16°15’00″S  , 168°07’00″E,

Summit Elevation 4377ft (1334m)
Current Vanuatu Volcano Alert Level: Level 2



The Alert Level for Ambrym Volcano remains at Level 2.

This means that the volcanic activity is still not stable. At this alert level, the volcanic activity is likely to remains at the same level for a while or decrease at any time but this volcano activity could also increase from any of the active craters of Benbow and Marum (including Maben-Mbwelesu, Niri-Mbwelesu and Mbwelesu). The area of risk remains in the caldera.

This is another reminder to all visitors to observe this volcano away from the Danger Zone, about 1 Km radius from Benbow, 2.7 radius from Marum up to 5.5 Km radius in the South East area (see dashed Zone on the Map below) to avoid volcanic projectiles, gas, ashes and any other volcano activity related incidents. Volcanic gas and ashes can also affect villages expose to trade winds.
All communities, villages, visitors and travel agencies have to seriously consider this information.
