Indonesia , Ibu :

Mount Ibu exhibited an eruption on Tuesday, October 17, 2023 at 12:42 p.m. WIT with the height of the ash column observed at ±600 m above the summit (±1925 m above sea level). The ash column was observed to be gray with thick intensity, oriented towards the East. This eruption was recorded on a seismograph with a maximum amplitude of 28 mm and a duration of 57 seconds.

Peru , Ubinas :

Analysis period: from October 10, 2023 to October 15, 2023. Arequipa, October 16, 2023.
Alert level: ORANGE

The Geophysical Institute of Peru (IGP) reports that the eruptive processes of the Ubinas volcano (Moquegua region) maintain low to moderate levels. During this period, slight emissions of ash, gas and steam were recorded which reached up to 700 m above the summit of the volcano, with seismic activity linked to magmatic fluids. Consequently, the Orange volcanic alert level is maintained.

During the analysis period, the occurrence of 225 volcano-tectonic (VT) type earthquakes was detected, associated with rock rupture processes that occur inside the volcano. In addition, 34 seismic signals were recorded, associated with the movements of volcanic fluids (gas and magma). On October 11 at 3:55 p.m., a signal associated with a volcanic ash pulse was recorded.

Surveillance cameras made it possible to identify emissions of ash (October 11) of gas and water vapor which reached heights of 700 m above the summit of the volcano, which were dispersed mainly towards the western sectors and southwest of the Ubinas volcano. On the other hand, monitoring of the deformation of the volcanic structure shows variations of less than 5 mm of displacement (slight tendency towards inflation). Satellite monitoring has not shown thermal anomalies in the Ubinas crater.

RECOMMENDATIONS
• Keep the volcanic alert level at ORANGE level.

DAILY REPORT ON THE STATE OF THE REVENTADOR VOLCANO, Monday October 16, 2023.
Information Geophysical Institute – EPN.

Surface activity level: High, Surface trend: No changes
Internal activity level: Moderate, Internal trend: No changes

Seismicity: From October 15, 2023, 11:00 a.m. to October 16, 2023, 11:00 a.m.:

The following table shows the number of seismic events from the reference station in the last 24 hours.

Explosion (EXP) 43
Long Period (LP) 29
Transmitting Tremor (TREMI) 2

Precipitation/Lahars:
Rainfall is not recorded. **In the event of heavy rains, these could remobilize the accumulated materials, generating mud and debris flows which would descend the sides of the volcano and flow into adjacent rivers.

Emissions/ash column:
Several emissions were observed with varying amounts of ash and with heights up to 600 m above the crater level, with directions to the West and Southwest.

Other monitoring parameter:
The FIRMS satellite system recorded 3 thermal anomalies in the last 24 hours.

Observation:
During yesterday night and early today, luminosity was observed at the crater level and the descent of incandescent material along all flanks of the volcano was recorded up to 800 m below the crater level. At the moment, the volcanic area is cloudy.

Alert level: Orange.
