COMMUNIQUE ON VOLCANIC ACTIVITY AT STROMBOLI, 30 July 2019, 10:49 h UTC (12:49 local time)
Istituto Nazionale di Geofisica e Vulcanologia, Osservatorio Etneo, reports that around 10:35 UTC, the thermal surveillance camera at 400 m elevation on the north rim of the Sciara del Fuoco shows a lava overflow onto the upper portion of the Sciara from the northern vents of the crater terrace. At the same time, lava continues overflowing from the central-southern crater area.

Indonesia , Tangkuban Parahu :
Mount Tangkuban Parahu is covered with thick volcanic ash following an eruption .
Travelers seeking to visit Mount Tangkuban Parahu’s crater in Bandung, West Java, should reconsider their plans for the time being as the tourist destination is still being cleaned following the volcano’s eruption last week.
“We are still cleaning up the area from ash, so we don’t want to force the reopening today [as previously planned],” Putra Kaban, the president director of Graha Rani Putra Persada, which manages the park, said on Monday.
At least three fire trucks have been deployed to the area since last weekend to clean the roads of volcanic ash.
“We are all exhausted. It’s impossible to force the reopening now,” he added as quoted by kompas.com.
The Center for Volcanology and Geological Hazard Mitigation (PVMBG) said the 2,284-meter volcano spewed ash 200 meters in the air.
PVMBG head Kasbani said thick volcanic ash had spread to the south and northeast.
“The eruption has a maximum amplitude of 38 millimeters with a duration of about five minutes and 30 seconds,” he said in a statement, calling on visitors to avoid spending the night at the tourist complex.
Kasbani also warned local residents to stay alert for a possible increase in volcanic activity.
“A phreatic eruption could happen at any time without any clear volcanic signals, » he added.

Colombia , Chiles / Cerro Negro :
Weekly activity bulletin of Chiles and Cerro Negro volcanoes
The activity level of the volcanoes continues at the level: YELLOW LEVEL ■ (III): CHANGES IN THE BEHAVIOR OF THE VOLCANIC ACTIVITY.
Following the activities of VOLCANS CHILES AND CERRO NEGRO, the COLOMBIAN GEOLOGICAL SERVICE (SGC) reports that:
For the period evaluated between 23 and 29 July 2019, seismic activity in the Chile – Cerro Negro volcanoes region increased from 840 to 1001 earthquakes, mostly from the previous week. cataloged as volcano-tectonic types associated with fractures of cortical material in the volcanic building. The earthquakes near the Chiles volcano have been located in the southern sector, at depths less than 5 km from the summit (4700 meters above sea level), the farthest and deepest to the southeast of the volcano. The maximum local magnitude reached was M4.0 on the Richter scale. An earthquake on July 25, 2019, at 7:38, was felt by residents of Chiles, Panan Indigenous Reserve and Cumbal Municipality (Nariño).
Analysis of other parameters of volcanic monitoring has allowed physico-chemical changes to be identified. This is why, in collaboration with the GEOPHYSICAL INSTITUTE OF THE IGEPN NATIONAL POLYTECHNICAL SCHOOL, a special report is being prepared to publicize these changes and their possible consequences. .
The Colombian Geological Service and the Institute of Geophysics of the National Polytechnic School of Ecuador are attentive to the evolution of the volcanic phenomenon and inform in a timely manner the observed changes.
