Authorities on Hawaii’s Big Island have declared a state of emergency as lava from the Kilauea volcano threatens residential communities and roads. Is there any way to stop a lava flow and save the homes in its path?
Article/story all about the Heimaey eruption which happened way back in 1973.
Update on volcanic activity in Iceland. Updated 5th September with radio interview.
Iceland has restricted travel around a cluster of volcanos, following an eruption near the Dyngjujokull glacier just after midnight.
A red alert warning issued by the Icelandic Met Office – the highest possible – indicates that “an eruption is imminent or in progress, and that a significant emission of ash into the atmosphere is likely”.
The magma from Iceland’s Bardarbunga volcano could be moving towards another large volcanic system. “We know there is a lot of molten rock sitting under the ground beneath Askja, which is a major volcanic system. If this molten rock hits that, we know it is likely to trigger it to erupt.
“But who knows, it may just stop. It is still at 5km-depth, and it is possible it could freeze there and not a lot more will happen. That is perfectly plausible.”
Very exciting….! I saw this and had to share it with you. For your GCSE studies look for causes (look at related stories to the right of the actual article) effects (primary and secondary) and responses (short term and long term). Make a note of the case study time place and date, then list specific […]
Iceland has issued a red alert to the aviation industry for the Bardarbunga volcano, meaning significant ash emissions are likely. At least the volcano is getting this over and done with before we visit!
Cool video briefly talking about tsunamis (GSCE).
Exciting, lets hope its settled down for our visit in February!
An orange alert indicates that a volcano is showing “escalating unrest with increased potential of eruption”, or is erupting without any major volcanic ash emissions.
A red alert means that an eruption is “imminent”, or is underway with “significant emission of volcanic ash into the atmosphere”.
The ash cloud produced by the 2010 Eyjafjallajokull eruption led to hundreds of thousands of passengers being affected by flight restrictions.

How do the effects of earthquakes differ in countries at different stages of development? For the exam you will need to know 2 case studies very well, one from an MEDC (more economically developed country) and one from an LEDC (less economically developed country). You will need to be able to explain how and why […]
