While most of the world is watching Washington DC for the next major earth-rattling , someone needs to keep an eye on , where all four of its major es are exhibiting signs of potential real s of the global winter kind.

Seismic activity tells us we need to be more vigilant than usual but not much more than that now. She is trying to tell us something more than we may understand not completely.

Geophysicist tells ’s Fréttablaðið newspaper (Google translated) that he’s most concerned about , a large in southern that has had multiple earthquakes in its caldera recently, with one measuring 4.3 magnitude. has a long history of regular s every 60 to 80 years. With its last major in 1918, is overdue.

That regularity is a trait of all of the major es in , which concerns Einarsson.

They are created to behave fairly regularly over the last decade with s in 1998 and 2004 and 2011. There is an increasing seismic activity there, slowly, and it plans to s in the coming few years. , also in southern , was on a 10-year schedule but its last blast was in 2000 so it’s overdue as well. Einarsson worries about because its s have occurred without warning. However, current measurements show its magma chambers filling and that’s an ominous precursor.

Northeast of and are and . is the largest and most powerful in and was responsible for the six-month-long 2014-15 Holuhraun . Its magma chambers refilled quickly and earthquakes of magnitude 4.3 and 4.0 were felt there this week. The has a seven-year average with the last occuring in 2011, but Einarsson says its magma chambers are also loaded and ready.

Growing seismic activity points to an in the next few years.

was formed by the where the Eurasian and North American Plates are moving apart. The area around the island has a higher temperature than the rest of the mantle and its own mantle has a higher concentration of stream-producing water. These conditions combine to make one of the most active volcanic regions in the world, with major s occurring somewhere on the island about every three years. While there are at least 30 volcanic system in , the most dangerous are the big four that Einarsson is currently worrying about.

Fortunately, he’s right on top of these es – seismically speaking – and can provide ample warnings to ers … right?

We can say little what happens next week but we can say what will happen in the next hour.

The next hour? Four of the world’s biggest es are getting ready to erupt and the best warning those nearby can get is an hour? All of a sudden, Washington isn’t looking so bad.
