Because this ash is comprised of fine glass particles and is toxic when it is breathed in humans and animals in the immediate vicinity often experience respiratory problems. It erodes by impacting compressor blades and vanes and removing materialand abrades by three body interactions between the rotating blade ash particle and compressor annulus.

If they are bigger than 2 microns but still pretty small then they let sunlight in but dont let heat radiation from the surface out and the earth gets warmAnyway if you have enough large explosive eruptions then the theory.
Volcanic ash damage. Thick volcanic ash on the roofs can result in excessive loading causing roof collapse. 112012 Volcanic ash fall can cause damage and disruption to wastewater systems both sewage and stormwater. Content is summarized from expert and peer-reviewed sources.
In point of fact volcanic ash is extremely hazardous to flying aircraft since it could cause much damage including engine and instrument failure. When this ash descends and collects on the rooftops of buildings the likelihood of the roofs collapsing increases. The ash consists of small rocks crystalline material and glass shards.
Both the indoor and outdoor units pf air conditioners have electric motors driving the compressor and air circulation fans. 9302011 Volcanic ash as a hard substance damages gas turbine compressors. This is especially so when heavy rain on the ash deposits make the ash heavier.
Damage to buildings and building support systems from volcanic ash can range from minor cosmetic damage to building exteriors through to catastrophic structural damage in extreme cases. Ash can enter and block pipes and sumps can cause accelerated wear on motors and pumps and can cause serious damage to wastewater treatment plants WWTPs. 10312014 Heavy ash fall can also inhibit road and rail traffic and damage vehicles.
When mixed with rainfall volcanic ash turns into a heavy cement -like sludge that is able to collapse roofs. Engines of jet aircraft have suddenly failed after flying through clouds of even thinly dispersed ash. If the ash particles are really small 2 microns then they block out incoming sunlight and the earth gets cool.
In most eruptions volcanic ash causes relatively few health problems but generates much anxiety. 442009 Volcanic ash is a significant hazard to aviation causing engine failure damage to avionics systems and abrasion to exposed airframe parts. Volcanic-ash hazards are far reaching and disruptive affecting more people infrastructure and daily activities than any other eruptive phenomena.
3252020 Volcanic eruptions throw large amounts of ash. Air conditioning and ventilation equipment is particularly vulnerable to damage from volcanic ash. Acidic ash can also damage vegetation leading to crop failure.
Inside the engine small concentrations of ash particles can cause extra engine wear. 452019 Volcanic ash is a mixture of rock mineral and glass particles expelled from a volcano during a volcanic eruption. This web encyclopedia provides information on the impacts of volcanic ash and mitigation strategies for dealing with them.
Damage to buildings and structures from volcanic ash can vary from minor cosmetic damage to building exteriors to major structural damage in severe cases. In this Chapter we describe the hazards impacts quantification and the regulatory environment associated with the ashaviation problem. People can be more fearful of the health hazards of volcanic ash and gases than of the risk of dying from more major hazards such as pyroclastic flows.
The ash can damage both the motors and the fan bearings. They tend to be pitted and full of holes which gives them a low density. 1132020 According to the US Geological Survey volcanic ash can infiltrate nearly every opening and scratch most surfaces especially between moving parts of vehicles.
In 1991 Mount Pinatubo erupted in the Philippines at the same time that a massive tropical storm wreak ed havoc in the area. Ash particles can clog air-filtration systems which can then lead to overheating and engine failure. Volcanic ash can cause internal-combustion engines to stall by clogging air filters and also damage the moving parts of vehicles and machinery including bearings and gears.
Impacts on sewerage and stormwater drainage networks. The particles are very smallless than 2 millimeters in diameter.
