An eruption in 1996 saw much of this glacial ice melt, causing a flood that washed away the country's main ring road.

The glacial ice and water cause the magma to cool very quickly, pulverising it into tiny fragments of rock.

A few days after the first opening, another vent broke four miles up the mountain, 600ft beneath the glacial ice cap.

Experts who captured the photo evidence warn melting glacial ice will raise sea levels.

In the darkest depths of the oceans, in the deepest caves and mines and even buried within glacial ice, we find microbes eking out an existence.

At my feet was a glacial lake, rain pinching its surface.

It's a fresh water glacial lake more than 27 miles long.

I soon find it - a series of terraces marking the successive shorelines of a glacial lake created when ice dammed the valley.

As the ice sheet covering the area retreated, water from spillways and meltwater channels pushed a huge amount of sediment and sand into the glacial lake.

His research there on natural glacial lake dams, prone to periodic collapse, was crucial for preventing future flood disasters.

The pace of glacial retreat and a rise in sea levels confirm it.

These surfaces are usually exposed above modern sea level when a heavily glaciated area experiences a glacial retreat, causing water levels to rise.

Research also indicates that the glacial retreat was proportionately greater in the 1990s than in any other decade over the last 100 years.

The glacial retreat has an interesting side effect, an increase in the frequency of earthquakes in the region.

A study which examines rock lichen in order to determine glacial retreat was begun in 1996.

It needs to be eaten at almost glacial speed.

Yet still we proceed with glacial speed towards a tentative easing an agonising ten days away.

Nice ought to be faster; some patients still haven't taken lenalidomide because of the glacial speed of the process.

When costs fall, they cut our bills at glacial speed.

The boutique-style hotel has a roof top pool, reliable internet (albeit at glacial speeds), big bathrooms and good service.

Under our boots the ice hides a labyrinth of tunnels, complex caves and trickling fresh glacial water.

He survived on the chocolate and glacial water — and hope as pals raised 14,000 for the rescue operation.

The volcano ceased erupting soon after breaching the surface of the glacial water.

Printed on both sides, the cards show pictures of glacial water, taxidermied birds, and of the same face, a little older.
