Volcanic pyroclastic flows destroyed the airport terminal building and damaged the runway.
Zollinger(1855) puts the number of direct deaths at 10,000,probably caused by pyroclastic flows.
The partial collapse of the dome generated pyroclastic flows which travelled down the eastern side of the volcano and into the sea.

The volcano unleashed lava flows, poisonous gases, and pyroclastic flows destroying nearly 19 squares kilometers of land, particularly in Mambajao.
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.

Pyroclastic flows and regular ash falls generated by Montserrat's active volcano combined with acid rain to inflict substantial damage on the environment.2.
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.
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.
The March eruption collapsed the dome that had been growing since the last eruption in November and caused pyroclastic flows, volcanic explosions and mudflows.
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.
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.
The accompanying pyroclastic flows destroyed the evacuated communities of St. Patrick's, Gingoes and Morris and caused severe damage to Trials, Fairfield and Kinsale, all to the south-west of the volcano.33.
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.
The heterogeneous material of debris avalanches mixes with fresh pyroclastic flows, sometimes in a 1:1 proportion, which modifies its outer appearance and particle-size characteristics.
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.
Further collapses and pyroclastic flows are anticipated. These are unlikely to pose a direct threat to areas outside the exclusion zone, 10 but might result in ash fall in populated areas.
Moreover, not only at a few of the monstrous power of explosions, a global earthquake,the movement of lava and pyroclastic flows high, containing hydrogen sulfide, but also a long time after the accident.
The juvenile material of the pyroclastic flows and surges occurs as particles of an irregular"lumpy" form, where the crystals are enclosed in thin jackets of transparent glass and welded with one another merely in a few points.
The large content of an oxidized resurgent material in the October 23 pyroclastic flows and a significant change of the dome's morphology suggest that part of the old edifice was destroyed at that stage of the eruption.

The pyroclastic flow.
