Poas , Turrialba , Costa Rica :

Poas Volcano in Costa Rica was very active this Friday, this time the eruption included ash .

2 JUNE 2017. Once again the Poás Volcano interrupted its relative calm period and during the afternoon of this Friday, June 2, Poás Volcano presented a couple of small size eruptions which included an ash column.

So far, this volcano´s activity had consisted mostly of phreatic eruptions, which means they contained mostly steam and vapor; however, the eruptions today as it was clearly captured by the cameras of the National Seismology Network, included ash.
The activity was registered at 1:30 p.m. local time, and it was followed by several smaller eruption and another big one at 5:30 p.m. which reached 600m above the crater and 3,308 meters above sea level.

The images also show that most of the water in the lake has disappeared leaving only a small quantity in the north sector. The column of ash was being dispersed to the West.

 

Activity report of the Poas and Turrialba volcanoes on 3 June 2017 updated at 11:00 AM.

Poas Volcano.
The Poas volcano, with a nearly 24-hour Tremor, had an ash eruption in the morning, beginning with low ash emissions and around midday the eruption occurred, more intense. It continued throughout the day, last night, at dawn and still today. During the night and early morning, it was accompanied by strong incandescence and ballistic activity that fell near the crater.
The height of the ash column was between 300 and 500 meters above the crater. The direction of the wind changed from southwest to northwest. There have been reports of ash falls in Alajuela, Grecia and Sarchí. On a cloudy day, the activity has not been seen directly today. Since the beginning of the eruption, the seismic signal has Lp earthquakes and some volcano – tectonic earthquakes, the tremor signal is not present.

Turrialba Volcano:

This volcano has maintained a degassing activity, with a gas plume up to one kilometer in height alternating with ash emissions that have reached 300 meters above the crater and have probably fallen around the volcano. The direction of the wind changed from southwest to northwest. There are no reports of ash falls
The ash and the seismic signal have Lp earthquakes.

Popocatepetl , Mexico :

3 June 11.00 (3 June, 16.00 GMT)

In the last 24 hours, with the monitoring systems of the Popocatepetl volcano, 220 low intensity exhalations and 15 explosions were identified. It was recorded the most violent at 03: 49h with emissions of fragments at a distance of 200 m of the crater,. Probably the others were accompanied by steam, gas and ash, because of the cloud conditions, it was not possible to see these emissions. In addition, eight volcano – tectonic earthquakes, six recorded yesterday; The other two today, all of a preliminary magnitude between M1,2 and M1,7. In addition, 123 minutes of harmonic tremors of low amplitude were recorded.

 

During the night, for short periods of time, it was observed glow over the crater.
At the time of this report, there is no visibility on the volcano due to the cloudy conditions in the area. However, early in the morning, volcanic emissions to the northeast were observed.

CENAPRED asks not to approach the volcano and in particular the crater.
The volcanic alert semaphore of the Popocatepetl volcano is located in Amarillo Phase 2.

 California Volcanoes ,  United – States :

Current Volcano Alert Level: all NORMAL
Current Aviation Color Code: all GREEN

Activity Update:
All volcanoes monitored by CalVO using telemetered, real-time sensor networks exhibit normal levels of background seismicity and deformation. Volcanoes monitored include Mount Shasta, Medicine Lake Volcano, Clear Lake Volcanic Field, Lassen Volcanic Center, Long Valley Volcanic Region, Coso Volcanic Field, Ubehebe Craters, and Salton Buttes.
Observations for May 1, 2017 (0000h PST) through May 31, 2017 (2359h PDT):

Mt Shasta: Six earthquakes of M1.0 or greater were detected, with the largest registering M2.71.
Medicine Lake: No earthquakes at or above M1.0 were detected.
Lassen Volcanic Center: No earthquakes at or above M1.0 were detected.
Clear Lake Volcanic Field: Three earthquakes of M1.0 or greater were detected, with the largest registering M1.20. [Note: The typical high level of seismicity was observed under the Geysers steam field located at the western margin of CLVF. The largest event was M2.90].

 

Cone in Coso Volcanic Field

Long Valley Volcanic Region: In Long Valley Caldera, 10 earthquakes of M1.0 or greater were detected, with the largest event registering M2.04. No earthquakes at or above M1.0 were detected in the Mono Craters region. No earthquakes at or above M1.0 were detected under Mammoth Mountain. [Note: The typical high level of seismicity was observed south of the caldera in the Sierra Nevada range. The largest event registered M2.21].
Ubehebe Craters: No earthquakes at or above M1.0 were detected.
Salton Buttes: Nine earthquakes of M1.0 or greater were detected, with the largest registering M2.72.
Coso Volcanic Field: The typical high level of seismicity was observed, with 23 earthquakes M1.0 or greater. The largest registered M2.09.

The U.S. Geological Survey will continue to monitor these volcanoes closely and will issue additional updates and changes in alert level as warranted.
