Italy , Stromboli :

PRESS RELEASE ON STROMBOLI’S ACTIVITY.

The National Institute of Geophysics and Volcanology, Osservatorio Etneo, reports that monitoring networks recorded a sudden change in monitored parameters at 5:58 p.m. (16:58 UTC).
In particular, a thermal anomaly is observed from the surveillance cameras.

 

PRESS RELEASE ON STROMBOLI’S ACTIVITY. [UPDATE n. 2]

The National Institute of Geophysics and Volcanology, Osservatorio Etneo, reports that at 16:57 GMT through surveillance cameras, an explosion of greater intensity was observed in the area of the North crater. The products emitted fell abundantly along the Sciara del Fuoco.
The explosion on the seismic trace is not particularly intense but is followed by a signal indicating a landslide.
Data from the Stromboli GPS network does not show significant variations.

 

PRESS RELEASE ON STROMBOLI’S ACTIVITY. [UPDATE n. 3]

The National Institute of Geophysics and Volcanology, Osservatorio Etneo, reports that at 16:57 GMT, there was an explosion that was energetically more intense than ordinary activity but could not be classified as a major explosion. The analysis of INGV-OE surveillance cameras also revealed that the products generated by this explosion fell back along the Sciara del Fuoco. Further lava overflow from the North Crater area is also visible from around 7:05 p.m. GMT.
The seismic signals do not show any significant change from the previous update.
Data from the Stromboli GPS network does not show significant variations.

Further updates will be communicated shortly.

Earthquake swarm in Okataina Volcanic Centre , Published: Mon Jan 25 2021 10:30 AM

A swarm of shallow earthquakes has occurred in the Okataina Volcanic Centre, Bay of Plenty, this morning – the two largest were a M4.5 and a M4.9. The larger event was widely felt across the upper North Island with more than 5200 felt reports.

 

We’ve recorded over 68 events since 7.47 am this morning ranging in size from <M2 to M4.9. Okataina Volcanic Centre lies east of Rotorua and is one of two active caldera volcanoes in the Taupo Volcanic Zone.

Earthquake swarms are common in the Taupo Volcanic Zone, especially in the area between Rotorua and Taupo which is tectonically active. The last swarm with quakes of this size within the caldera was in July 2004 located just north near Lake Rotoehu and before that in 1998 just to the south of today’s sequence.

Saint Vincent , Soufrière Saint Vincent :

LA SOUFRIÈRE BULLETIN , JANUARY 24, 2021 8:00 PM

Full advantage was taken of the general clear conditions at the summit today to achieve several tasks.

Aerial photographs and video of the volcano were taken, through the assistance of Drone Pilot Rommel De Freitas and Professor Robertson.
The electronics team led by Mr Ian Juman installed a camera and EDM reflector on the southern crater wall. The camera will be used to help track growth of the dome while the EDM reflector would be used to check for possible instability of the southern crater wall.

The other members of the Seismic Research Centre (SRC) and Soufriere Monitoring Unit Team spent the day at the Belmont Observatory testing and preparing other monitoring equipment for future deployment.

NEMO and the SRC will be hosting a Virtual Community Meeting with residents of Georgetown on Tuesday 26th January, 2021, beginning at 6:00 p.m. to update residents on the latest development at the La Soufriere Volcano and to discuss the Georgetown Community Evacuation Plan.

Alert level remains at Orange. The volcano continues to exude magma on the surface and steam can still be observed from the Belmont Observatory. Persons living in areas close to the volcano should expect strong sulphur smells for several days to weeks, depending on changes in wind direction.

Mexico , Popocatepetl :

January 24, 11:00 a.m. (January 24, 5:00 p.m. GMT)

During the last 24 hours, thanks to the monitoring systems of the Popocatepetl volcano, 93 exhalations and 886 minutes of low to medium amplitude tremor have been identified, accompanied by emissions of water vapor, volcanic gases and small amounts of ashes.

At the time of this report, there is an emission of volcanic gases and light amounts of ash scattered in a north direction.

CENAPRED urges NOT to APPROACH the volcano and especially the crater, because of the danger posed by the fall of ballistic fragments and, in the event of heavy rains, to stay away from the bottom of the ravines because of the danger of flows mud .

The Popocatépetl volcanic alert semaphore is in YELLOW PHASE 2.
