In Krakatau, the activity remains strong, characterized on July 24, by continuous tremor of a dominant amplitude of 65 mm.

Due to the fog, the summit could not be observed.

 

Recent photos have been kindly shared by Pascal Blondé, on site with a "Special eruption of Adventure and volcanoes" from July 16 to 22.

He comments on the site:

"Landing on the island of Krakatau, and camping on the beach as usual, we could say. The forest hides the summit and hides us the eruptions but the frequent din does not deceive, explosions and fallout of blocks succeed one another. As soon as you leave the forest the ground is littered with recent volcanic bombs. Attention danger! To approach is to play with fire. The show is there, real fireworks from hell. "

A stop at the monitoring station of Krakatau, located on a small hill in the village of Pasauran not far from Carita, to observe the seismograms, reveals that Guy de Saint Cyr has "always good foot-good eye !"

A fourth episode was called as "breath"

At Etna, Boris Behncke and Marco Neri report Strombolian activity at two summit craters, the Bocca nuova and the northeast crater.

The volcano shows signs of waking after 14 months of calm since its last eruption.

To watch with the return of tourists on the summits.

At Kilauea, fissure 8 continues to feed the lava flow, but lower levels are found in the channel.

In an area northwest of the Kapoho crater, frequent overflows have created a sort of perched pond, in which large pieces of rock are stagnating and accumulating.

Entries in the ocean have grown from Ahalanui to Pohoiki with dozens of fingers spilling lava at sea.

On the morning of July 24, lava covered the surf spot at Shackset threatening Dead Trees and the boat ramp after reaching Pohoiki's car park. A wooded area upstream of the pouring front has been burned.

Bruce omori reports an accumulation of lava, which is beginning to establish a small hill.

At the top, marked by intense seismicity, the collapses continue, and new fractures appeared on Highway 11.
