News Stories relating to "volcano"

Volcano, that is - While the effects of the Icelandic volcano Eyjafjallajokull are slowly beginning to dissipate, there are new worries about the Katla volcano, which is hidden beneath another ice cap 12 miles away. It erupts much more often than Eyjafjallajokull and with much greater force and an even larger plume of ash.

Climate change isn't just melting ice caps, it's about melting magma too. This, in turn, will lead to more volcanic eruptions. The recent volcano in Iceland may have disrupted air travel, but what's even more amazing is that a huge volcanic eruption in Indonesia 74,000 years ago changed the course of evolution!

The largest ice cap in...

Could last for weeks or even months. - On Thursday, April 14 thousands flights out of many European airports were shut down due to a huge cloud of volcanic ash from an eruption in Iceland. Eyjafjallajokull is astratovolcano like Mt. Vesuvius. They are characterized byexplosive eruptions that tend to end as abruptly as theystart...

It's Mount St. Helen's again! - Is there a supervolcano lurking underneath Mount St. Helens in Washington State, which already erupted in 1980? Scientists now have special instruments that enable them to "peek" beneath the seemingly dormant volcano, and they have seen a large amount of semi-molten rock, which could set off...

Another indication of the high level of volcanic activity worldwide is that a large new island has appeared in the South Pacific, near Tonga, in an area so isolated that it has gone virtually unnoticed by scientists. A cruising yacht and a fishing boat have both reported sailing into a vast area of floating pumice, and the captain of the...

Volcanic activity in the Pacific Ring of Fire appears to beincreasing as volcanoes in Japan and New Zealand becomeactive and eight volcanoes in the Phillipines are put on thewatch list.

Mt. Merapi on the island of Java continues to emit largequantities of gasses and magma, endangering the lives ofthousands who live on its slopes.

A mysterious bulge in the Earth's crust is growing in Oregon, meaning magma underneath the surface is on the move and could erupt into a volcano soon. The bulge is in the Three Sisters mountains, which are remnants of volcanoes in the Cascade mountains that were thought to be extinct.

Lucy Sherriff writes in The Register that there was...

On Thursday the Indonesian government placed 11 volcanoes oneruption watch, as volcanism continued to increaseworldwide and especially in the Indian Ocean area. On April12 alone, there was activity recorded at asurprisingly large number of volcanoes. Mt. St. Helens inthe US, Canlaon in the Phillipines, Chikurachki and Ebko inthe Kurile Islands...

There are enough supervolcanoes on Earth to wipe out much ofthe planet and they may "wake up" much sooner than wethought. Supervolcanoes explode with a force that isthousands of times that of a normal volcanic eruption.Earthquake experts once thought it would take hundreds ofthousands of years for the reservoirs of molton rock (calledmagma)...
