Everyone loves a "supervolcano"*. According to a recent report, Los Angeles will be erupting from underneath Yellowstone Caldera (Wyoming). OK, not really, but apparently there has been 7 cm of uplift underneath the footprint of the Yellowstone Caldera since 2004, which is a pretty good amount of uplift. Whether this uplift is caused by new magma intruding, volcanic gases collecting or hydrothermally spawned (however, in the article, we are to believe these unnamed "researchers" that it is magma). I'll keep an eye out for more on this, but it sounds like this is just another "more uplift!"…

Is this a big problem? Should the evacuate? Should those of us living only a few states away start wearing earplugs?
The paper reporting this, in the current issue of Science, concludes:
The caldera-wide accelerated uplift reported here is interpreted as magmatic recharge of the Yellowstone magma body. Although the geodetic observations and models do not imply an impending volcanic…
