YELLOW LEVEL ■ (III): CHANGES IN THE BEHAVIOR OF VOLCANIC ACTIVITY
Following the activity of the CHILE and CERRO NEGRO volcanoes, the COLOMBIAN GEOLOGICAL SERVICE (SGC) reports that:
During the period evaluated, between 14 and 20 August 2018, seismicity in the Chiles – Cerro Negro volcanoes region showed a significant increase in the number and energy released compared to the previous week, from 31 at 580 earthquakes. Almost in their entirety, these earthquakes corresponded to rock break events in the volcanic building.
The localized earthquakes have their epicentres to the south and south-west of the Chiles volcano, with distances between 0.5 and 7.5 km, depths between 1 and 7 km from the summit of Chiles (4700 meters). ‘altitude). In general, the magnitude of these earthquakes did not exceed 1.8 on the Richter scale, however, an earthquake occurred on August 18 at 2:45 am, 2.5 km southwest of Chiles volcano. , with a depth of 4.5 km and a magnitude of 2.7 M, which was not reported as felt.
The COLOMBIAN GEOLOGICAL SERVICE and the GEOPHYSICAL INSTITUTE OF THE NATIONAL POLITECHNICAL SCHOOL OF ECUADOR closely monitor the evolution of this seismic activity and the volcanic phenomenon and will inform timely changes detected.

Kīlauea summit and lower East Rift Zone
Seismicity and ground deformation are negligible at the summit of Kīlauea Volcano. On the volcano’s lower East Rift Zone (LERZ), only a few ocean entries are oozing lava; laze plumes are minimal. Sulfur dioxide emission rates at both the summit and LERZ are drastically reduced; the combined rate is lower than at any time since late 2007.
The Hawaiian Volcano Observatory (HVO) will continue to closely monitor Kīlauea’s seismicity, deformation, and gas emissions for any sign of reactivation, and maintain visual surveillance of the summit and LERZ.
HVO will continue to issue daily updates and additional messages as needed. The next status report will be issued tomorrow morning unless significant changes occur.

Guatemala , Pacaya :
Type of activity: Strombolian.
Morphology: Composite stratovolcano
Location: 14 ° 22’50˝ Latitude N; 90 ° 36’00˝ Longitude W.
Weather conditions: Clear
Wind: from the south at 10 km / h
Precipitation: 0.0 mm
Presence of white degassing fumaroles at a height of 600 m above the crater scattered by the southwesterly winds. The internal tremor associated with the rise of magma and gases on the surface is recorded, maintaining a lava flow in the North direction with an approximate length of 300 m.
