Well as everything goes quiet in Iceland mount Cleveland is waking up http://newsminer.com...ow_left_bullets Today it wasn't doing much but two days ago things were more interesting Thermal anomalies observed in satellite data over the past few days suggest that Cleveland Volcano has entered another period of volcanic unrest. In the past, the presence of thermal anomalies at the summit has been followed by moderate ash bursts, sometimes to aircraft flight levels. Therefore, AVO is raising the Aviation Color Code to YELLOW and the Volcano Alert Level to ADVISORY. The lack of a real-time seismic network at Cleveland means that AVO is unable to track local earthquake activity related to volcanic unrest. Unrest at Cleveland is frequent, and short-lived explosions with ash clouds or plumes that could exceed 20,000 ft above sea level can occur without warning and may go undetected on satellite imagery. Other matters Kilauea reached 10,000 days of eruption on the 22nd and is still chugging away. It worth looking at the table seeing how big this eruption is http://hvo.wr.usgs.g...torytable.html. There's no sign of it stopping any day soon either.

I'm nowhere near an expert on volcanoes but from what i can remember from one of my uni modules the injection of magma into the surrounding rock induces earthquakes through changes in pressure. Increased seismic activity is one of the main forecasting tools for predicting volcanic eruptions. Lots of volcanic activity, with increasing strength, is generally indicative that an eruption is likely to take place. As this volcano is sublglacial a large eruption is likely to inject a lot of ash into the atmosphere (e.g. like the 2010 eruption).

I quite like this site as it shows some in the UK that even the BGS site does not show, let alone the USGS site which hardly shows the UK at all, because of its high cut off rate outside the USA. (Sorry about all the abbreviations

Hopefully the region responsible will remain as active once it gets round to this side of the Sun.
