The word"Pyroclastic" is used several times.
INSIVUMEH reiterates that a chance on Pyroclastic flows is still very high.
Japan's Meteorological Agency has alerted people for volcanic rocks and Pyroclastic flows.
Meteorological Agency of Japan had alerted people for volcanic rocks and Pyroclastic flows.
Weather conditions, continuing activity at Fuego, poor air quality,
hot Pyroclastic flow deposits, and rain made rescue efforts difficult.
Much of the volcano's growth occurred during its first year,
while it was still in the explosive Pyroclastic phase.

Ignimbrite is a volcanic rock consisting mainly of pumice fragments,
formed by the consolidation of material deposited by Pyroclastic flows.
Scientists believe the town was most likely decimated by a Pyroclastic flow, a phenomenon that was unknown at the time.
This was followed by large-volume lava effusion that lasted 96 minutes,
and was interspersed with sporadic lava fountaining and/or Pyroclastic flows.
The action which started yesterday with floating smoking stones is continuing this morning,
hot Pyroclastic material is floating to the surface.
A VEI 5 eruption during 1963-64 produced Pyroclastic flows
and lahars that caused extensive damage and resulted in more than 1,100 deaths.
A large percentage of the volcano's growth occurred during that first year,
while it was still in the explosive Pyroclastic phase 1943.
Today we remember the 19 people who lost their lives in Pyroclastic flows during an eruption of SHV on 25 June 1997.
Here we can clearly see the opening in the crater from the 2010 eruption,
which generated extensive Pyroclastic density currents and later lahars.
Occasional larger eruptions have produced Pyroclastic flows
and lava flows that reached flat-lying coastal areas and entered the sea, sometimes impacting populated areas.
Historical eruptions have primarily produced small-to-moderate ash plumes that have occasionally damaged croplands and houses,
but lava-dome growth and Pyroclastic flows have also occurred.
As many as three Pyroclastic flows each day were detected by the seismic network,
and had runout distances exceeding 5 km in the Buyuan drainage.
I am guessing that(photographer)
Chris Horsley kept this on a long shutter setting in order to capture this impressive Pyroclastic('hot rocks') display at Yasur volcano during the night!
According to CONRED, as of 12 June, the number of people that had died due to the 3 June Pyroclastic flows was 110, and 197 more were missing.
According to CONRED, as of 3 July, the number of people confirmed to have died due to the 3 June Pyroclastic flows was 113, and 197 remained missing.
According to CONRED, as of 26 June, the number of people confirmed to have died due to the 3 June Pyroclastic flows was 113, and 197 more were missing.
According to CONRED, as of 19 June, the number of people confirmed to have died due to the 3 June Pyroclastic flows remained at 110, and 197 more were missing.
At any given time in the following weeks to months, this magma can eventually be erupted quietly as lava flows or
explosively as vertical eruption columns and Pyroclastic flows or both.
Brief explosive intervals occur every 8-
15 years which generate lahars and Pyroclastic flows, which have previously generated partial dome collapse
and destroyed part of the pre-existing dome(last occurred in 1994 and 2010).
At 0820 on 8 June a Pyroclastic flow descended the Las Lajas and El Jute drainages,
producing an ash plume that rose as high as 6 km and drifted W and SW.
Many human beings in the path of the water were also swept away and
drowned, and those spared a watery grave were burned to death in the path of a Pyroclastic flow.
At Santiaguito, regular explosions take center stage, sending thundering clouds of ash and gas a kilometer high,
which sometimes collapse and send searing-hot, billowing Pyroclastic flows careening several kilometers down the mountainside.
Pyroclastic flows
and lahars accompanying growth and collapse of the steep-sided active summit lava dome have devastated cultivated and inhabited lands on the volcano's western-to-southern flanks and caused many fatalities during historical time.
Last occurred 19th December 1930-
31 when large Pyroclastic flows travelled 12km from the summit covering
an area of 20km² and destroying 13 villages killing over 1,300 people(this type of eruption is heavily overdue).
