Eruptions of Fuego, Pacaya and Kilauea.

I resume the course of the volcanic news after an interruption due to the crashdown of my PC.

For the Fuego, a small summary of the eruptive activity since the day of June 3rd is essential:

On June 3rd, a paroxysm started around 6am local, producing pyroclastic flows; one of them traveled at least 8 km, and the accompanying plume reached 6,200 meters above the summit, or about 10,000 meters asl. The areas most affected by the pyroclastic flow are San Miguel Los Lotes, Alotenango and El Rodeo, located at the SSE.

The temperature reached within the pyroclastic flow was around 700 ° C (INSIVUMEH data)

Ash and lapilli falls are reported more than 25 km northeast of the volcano and Guatemala City 70 km to the east, causing the closure of La Aurora International Airport.

Lahars towards the Rio Pantaleón were triggered following heavy rains in the area. The last pyroclastic flow of the day is recorded at 18:45.

On June 4, seismicity returned to its usual level, and explosions at the rate of 5 to 7 per hour characterize the activity.
 

On June 5, the number of explosions increased to 8-10 per hour, accompanied by ash plumes rising to 5,000 meters; at 19:28, a pyroclastic flow borrows the drainage Las Lajas.

On the 7th of June, at the beginning of the evening, new pyroclastic flows descended the Las Lajas and El jute drainages, accompanied by a co-pyroclastic cloud rising to 6,000 meters asl.

On June 8, Insivumeh reported lahars in Santa Teresa, Mineral, Taniluyá and Ceniza barrancas, tributaries of the Pantaleón and Achiguate rios; these lahars are hot, emit fumes, and carry fine materials, and rocks 2-3 m in diameter, as well as tree trunks.

In parallel, pyroclastic flows are reported in El Jute and Las Lajas drainages, accompanied by co-pyroclastic plumes up to 6,000 meters asl.

The assessment given to 8 June / 8:30 by the Conred, is 109 dead, 197 missing, and 1,713,617 people affected by the climax and its aftermath.

At Pacaya, strombolian activity is maintained, and generated a lava flow on June 6 on the northeast flank, which reached 200 meters in 6 hours.

In Hawaii, in the eastern rift zone of Kilauea, the fountaining continues on fissure 8, partially obscured by a spatter cone 35 meters high, and feeds the lava flow towards Kapoho Bay, 6-7 June.

The lava goes into the sea in the area of ​​Vacationland Subdivision, creating a large plume directed towards the interior of the island and the southwest. The lava delta extended during the day, and a lateral lobe of the flow pushes northward through what remains of Kapoho Beach Lots subdivision.

In the night of June 7 to 8, the fountaining on fissure 8 reaches about 67 meters; no significant changes are observed on the lava field. The other cracks do not emit lava, but the cracks 24, 9 and 10 degass thoroughly.

The number of houses destroyed since the beginning of this eruption has reached 600 ... so 600 families are affected, combining the areas of Leilani, Kapoho and Vacationland, not to mention the farmers, and the many employees of these areas. .. what makes this the most destructive eruption for Hawaii, listed in modern times, according to the mayor of the County.

At the top, the inward collapse of the edges and walls of Halema`uma`u continues in response to the continuous subsidence of the summit.

On June 8, at 2:44 HST, a small summit explosion occurred, producing a quake equivalent to a magnitude four earthquake. According to satellite data, a plume was reported at a height of less than 3,000 meters .
