Vulcanian activity from the Santiaguito’s lava dome continues (image: @Centinela_35/x.com)

The extrusive-explosive eruption of the volcano continues.

Near-constant weak-to-moderate vulcanian-sized eruptions at regular intervals of 1 to 2 per hour continue.

Viscous, but gas-poor magma squeezes through the main conduit in search for the fastest way up to the surface and is being fragmented into grey ash-rich eruption plumes, rising up to about 14,000 ft (4,3 km) above the summit.

People are advised to avoid the sticky lava flow due to the strong heat which may cause burns and other serious injuries. The current hazards are also hot avalanches that can become mobilized into hot glowing currents (pyroclastic flows).
