Information on Mount Sinabung eruption, May 12, 2019.

An eruption of Mount Sinabung, North Sumatra, occurred on May 11, 2019 at 20:39, but the height of the ash column was not observed. This eruption is recorded on a seismogram of maximum amplitude of 9 mm and a duration of ± 33 minutes.

Hot spots are observed. Currently G. Sinabung is at level IV (SIAGA) with recommendations:
The public / visitors must not carry out activities within a radius of 3 km for the North-West sector, 4 km for the South-West sector, within 7 km for the South-South-East sector, in a radius of 6 km for the South-East sector and within a radius of 4 km for the North-East sector
Communities living along the river below Mount Sinabung should be aware of the potential of lahar descents, especially during heavy rains.

Kamchatka , Sheveluch :

VOLCANO OBSERVATORY NOTICE FOR AVIATION (VONA).

Issued: May 11 , 2019 
Volcano:Sheveluch (CAVW #300270)
Current aviation colour code:ORANGE
Previous aviation colour code:orange
Source:KVERT
Notice Number:2019-92
Volcano Location:N 56 deg 38 min E 161 deg 18 min
Area:Kamchatka, Russia
Summit Elevation:10768.24 ft (3283 m), the dome elevation ~8200 ft (2500 m)

Volcanic Activity Summary:
A growth of the lava dome continues (a viscous lava blocks extrude out on the northern part of it), a strong fumarolic activity and an incandescence of the dome blocks and hot avalanches accompanies this process. According to video and satellite data, a gas-steam plume containing some amount of ash on the height about 4.0-4.3 km a.s.l. continues to extend to south of the volcano.
Explosive-extrusive eruption of the volcano continues. Ash explosions up to 32,800-49,200 ft (10-15 km) a.s.l. could occur at any time. Ongoing activity could affect international and low-flying aircraft.

Volcanic cloud height:
13120-14104 ft (4000-4300 m) AMSL Time and method of ash plume/cloud height determination: 20190511/0310Z – Video data

Other volcanic cloud information:
Distance of ash plume/cloud of the volcano: 47 mi (76 km)
Direction of drift of ash plume/cloud of the volcano: S / azimuth 176 deg
Time and method of ash plume/cloud determination: 20190511/0250Z – Himawari-8

Guatemala , Pacaya :

Type of activity: Strombolian
Morphology: Composite Stratovolcano
Geographical location: 14 ° 22’50˝ Latitude N; 90 ° 36’00˝ Longitude O.
Height: 2,552msnm.
Weather conditions: Cloudy
Wind: South
Precipitation: 20.8 mm

Activity:
Due to weather conditions, there is no visibility at the moment. There are lava flows north to the Meseta. Avalanches occur in the direction of the lava flow, mainly where the slope is highest. Explosive activity is audible near the Mackenney cone in the Plateau region. The seismic station records the tremors associated with the rise of magma and gases on the surface.

Ash falls reported in: There are no reports yet
Sulfur odor reported in: No report yet.

RSAM seismic signals of the strong gas eruption this morning May 11, 2019 at 7:20 am
in the main crater of the Rincón de la Vieja volcano. Information: OVSICORI-UNA

Comments: The eruption consisted essentially of an emission of water vapor and magmatic gas that developed as a white column about 600 meters above the edge of the crater. The seismographs of the Rincon de la Vieja and Miravalles volcanoes managed by OVSICORI-UNA recorded a seismic signal associated with this eruption. It was not observed through the web cameras leaving water, sediments or rocks thrown out of the crater. Remember, however, to be careful near river beds and on bridges.
