Cigarette burns mark almost every inch of the filthy carpet and ash covers every surface of the tiny, two-bedroom residence.

The pyroclastic rock and the base surge deposits form an ash volcanic cone, while the ash covers a large surrounding area.

The ash covers much of these features.

Some critics said authorities overreacted by closing air space but tests showed the sharp ash particles could 'sandblast' jet engines.

Ash particles from eruptions can be found in ice core layers.

Representative ash particles are initiated at the volcano's location and then allowed to advect, diffuse, and settle within the atmosphere.

Near the volcano, the swirling ash particles in the atmosphere generated lightning, which in turn started many forest fires.

Due to the spherical shape of fly ash particles, it can increase workability of cement while reducing water demand.

In this case the ash plume ran out of steam in the high troposphere (below the stratosphere).

An eruption occurred at 8:20, am the same day sending an ash plume two miles into the sky.

The extremely fine ash particles and the large volume of steam from the glacial meltwater sent an ash plume hazardous to aircraft rapidly high into the upper atmosphere.

The water caused huge explosions as it hit the hot lava, generating more ash plumes.

The material in the ash plume eventually finds its way back to the ground, covering the landscape in a thick layer of many cubic kilometers of ash.

It can be used on heavy soils to improve drainage, but coal ash actually contains very little plant food, just small amounts of sulphur.

Coal ash contains very little plant food (perhaps small amounts of sulphur).

By 300 years the material would have the same radioactivity as coal ash.

Areas along the banks of the creek are covered in coal ash, coal silt, sand, and gravel.

Coal ash contaminants are also linked to respiratory diseases and other health and developmental problems, and have disrupted local aquatic life.

However, then came people completely covered in grey ash.

Your coals are ready when they're covered in grey ash and the flames have died down.

A short time later, grey ash starts to fall on the ship.

Others said saw bursts of fire and hot ash.

Seven helicopters were scrambled to the island but were unable to land in clouds of hot ash.

Airlines have been told to avoid the area after a vast column of flames, smoke, hot ash and toxic gas was sent up.

Volcanic earthquake and hot ash cloud events were reported to have increased from the previous day.

The day's volcanic activity was very high, with sequential hot ash clouds erupting from the mountain.

Others will spend weeks spewing ash, an extended smoke signal of their intentions, before the final cataclysmic eruption.

I sympathise: few people would want to risk going anywhere near a volcano spewing ash and smoke.

Erupting more than 30,000 years ago, the volcano spewed ash and cinders into the air much like a can of soda when shaken.

Other materials include egg shells, 100 per cent natural clothes fibres and wood ash in moderation.

Its crumpled leaves, sometimes mixed with wood ash, were applied to the afflicted spot.

One manual recommended cleaning a canvas by covering the surface with wood ash before washing it off.

For a natural toothbrush use alder or hazel twigs, sage or wood ash for toothpaste, and sinew for dental floss.

Other compostable materials include eggshells, coffee grounds, 100 per cent natural clothes fibres and some sawdust and wood ash in moderation.
