European airspace begins to reopen as the eruptions at Eyjafjallajökull settle down for the time being.

There are signs that the style of volcanism at Eyjafjallajökull has changed. Meanwhile, ash from the eruption continues to cause problems and has reached eastern North America.

European airlines took test flights over Europe today to see the effect of the Eyjafjallajökull ash on their jets – but it is still unclear when flights over Europe will return to normal.

Could increased volcanism and deglaciation be linked? It is hard to tell, but fascinating to ponder.

Although the world's eyes are on Iceland, there is other volcano news, including the high cost of a potential Vesuvius eruption, new dome growth at Colima and all the week's volcanic activity from the Global Volcanism Program

With no clear end in sight for the Eyjafjallajökull ash, airplanes are still grounded across Europe and in Iceland, you can add severe flooding to the ash hazard as well. UPDATED!

Large swaths of European airspace remains closed due to Eyjafjallajökull eruption – and there is no clear end in sight. UPDATE: Now with chemical composition of the ash!

Eruptions had hit the million mark. Thanks to everyone!

The eruption we've been following for weeks in Iceland has now begun to disrupt life in Europe, as the ash from the new explosive phase has closed airspace over much of northern Europe.

It has now been confirmed that the Eyjafjallajökull-Fimmvörduháls eruption has opened a new fissure underneath the Eyjafjallajökull glacier. This has caused a number of volcanic-triggered floods in the area and prompted more evacuations.

Iceland may have ordered evacuations near Eyjafjallajökull-Fimmvörduháls after increased earthquakes underneath the Eyjafjallajokull ice cap, leading to fears of a potential jökulhlaup (volcanically-triggered volcanic flood).

Journalists can't stay away from the term "supervolcano" (read at your own peril), the eruption in Iceland marches on and Redoubt settles down. UPDATE: Is the Icelandic eruption winding down?

Activity has died down significantly at the Eyjafjallajökull-Fimmvörduháls eruption in Iceland – is this the end?

Following a series of earthquakes last week on the island of Sicily, Italy's Mt. Etna is showing signs that new eruptions are on the way.

Recent data collected by the ESA Venus Express suggest that Venus might have had very recent lava flows.

A new earthquake swarm has started near the summit of Redoubt in Alaska – does this mean an eruption will soon follow?

The NASA Earth Observatory has posted some great new shots of volcanoes from space, including four volcanoes erupting at once and the latest from the Icelandic eruption.

The current Eyjafjallajökull-Fimmvörduháls eruption is exactly what you might expect for an eruption in Hawai`i … in Iceland … actually, both!

The largest volcano on Hawai`i's big island is officially moved to "Normal" status after the inflation of Mauna Loa ends.

Tourists are creeping ever closer to the Eyjafjallajokull-Fimmvörduháls (at their own peril) and rumors of an eruption at Taal in the Philippines prove to be false.
