The pyroclastic flows of the first portion had steep frontal and lateral sides and were very thick max. 10 m.
Villages within 8 km(5 mi) of the volcano were destroyed by pyroclastic flows, killing more than 2,000 people.
The second episode of pyroclastic flows was accompanied by a partial collapse of the dome 0.006 km3 in volume.
Zollinger(1855) puts the number of direct deaths at 10,000,probably caused by pyroclastic flows.
Formation of pyroclastic flows took place during the final stage of the eruption, possibly beginning about 07:47 a.m.
The first minor eruption in 1948 caused little damage and loss of life, but in 1949,the larger eruption caused 79 deaths due to pyroclastic flows.
The volcano unleashed lava flows, poisonous gases, and pyroclastic flows destroying nearly 19 squares kilometers of land, particularly in Mambajao.
Their products are mainly alkaline and include a wide range of lavas: from basalt to rhyolite and phonolite,as well as pyroclastic emissions and slag.
Most of the pyroclastic flows were deposited between two SE-trending spurs of the dome known as the Northern and Southern Ridges.
On June 15, Mount Pinatubo spewed an ash cloud 40 km(25 mi) into the air andproduced huge pyroclastic surges and lahar floods that devastated a large area around the volcano.
Most deaths were caused by pyroclastic flows and lahars, deadly hazards that often accompany explosive eruptions of subduction-zone stratovolcanoes.
Ash interlayers produced by individual eruptions usually have a maximum thickness around the pyroclastic flow deposits and near the dome, its values ranging between 5 and 10 cm.
Pyroclastic flows and regular ash falls generated by Montserrat's active volcano combined with acid rain to inflict substantial damage on the environment.2.
The partial collapse of the dome generated pyroclastic flows which travelled down the eastern side of the volcano and into the sea.
When pyroclastic flows and mudflows began occurring regularly, the capital, Plymouth, was evacuated, and a few weeks later a pyroclastic flow covered the city in several metres of debris.
His main interest was in volcanology(magmas and pyroclastic rocks), structural geology and tectonics, especially sliding tectonics.
The March eruption collapsed the dome that had been growing since the last eruption in November and caused pyroclastic flows, volcanic explosions and mudflows.
On the volcano's southwest flank is the pyroclastic cone La Olleta, which is not currently active, but may have erupted in historical times.
During the past 11,000 years, Nevado del Ruiz passed through at least 12 eruption stages,which included multiple slope failures(rock avalanches), pyroclastic flows and lahars leading to partial destruction of the summit domes.
This material fell out of ash clouds that rose above the pyroclastic flows during their movement and also was deposited from ash clouds produced by explosions on the dome.
The rise of pressurized gas makes the dome unstable, is associated with the continued low level earthquake activity andis responsible for minor explosions, some pyroclastic flows and the ash venting.
If the dome growth switched to the north or north-west, pyroclastic flows could reach as far as the sea and surge clouds could affect the upper reaches of the Belham Valley.
Scientists have simulated this situation and came to the conclusion that all living within the radius of 1,200 km will be destroyed already in the first minutes after the eruption,as the area adjacent to the volcano will suffer from pyroclastic flows, consisting of red-hot gas and ash.
As is the case for many subduction-zone volcanoes,Nevado del Ruiz can generate explosive Plinian eruptions with associated pyroclastic flows that can melt snow and glaciers near the summit, producing large and sometimes devastating lahars mud and debris flows.
As a by-product of this activity, sulfur,sulfur dioxide gas and silicate pyroclastic material(like ash) are blown up to 200 km(120 mi) into space, producing large, umbrella-shaped plumes, painting the surrounding terrain in red, black, and white, and providing material for Io's patchy atmosphere and Jupiter's extensive magnetosphere.
