Mount Saint Helens




We are entering an age of increases seismic activity in the Pacific Northwest, and don't look now, but Mount Saint Helens is starting to expand and wake up:

One such story of a volcano recharging is being written right now at Mount St. Helens in Washington. Since the start of 2016 (see below), an earthquake swarm has been detected underneath the currently-quiet Washington volcano. These earthquakes have been occurring from depths of ~2 to over 7 kilometers beneath the volcano. USGS volcanologists and seismologists are interpreting this swarm as a response to the slow “recharging” for the volcano, where new magma is rising up underneath St. Helens as it slumbers. As the magma intrudes, it imparts pressure on the rock around it and it heats up water/releases gases that can add to that pressure. This generates small earthquakes as the rocks shift in response to that stress.






Yeah, don't run away just yet:

As the USGS report on the earthquake swarm mentions, there are no other signs of potential eruption right now: no changes in gas emissions, no deformation, and no shallow seismicity (<2 kilometers) that are generally associated with an impeding eruption. However, it does mean that even as St. Helens sleeps, the magma that will likely take part in the next eruption is working its way up towards the surface, likely stopping along the way to crystallize and interact with the residue of previous eruptions.

I remember the ash cloud and the overall panic caused when the mountain blew up in May of 1980. Here's to hoping we have a plan in place and a way to deal with what might happen if we see another massive eruption.

Democrats Are Trying to Save America

Never forget that Trump is a bum. A cheating, lying, stealing bum. He's the kind of bum that gives actual bums (who are usually down on their luck and doing the best they can) a bad name. He's a bum on purpose, you see, and that's the kind of bum that the American people want to see thrown out of office. He's never going to be presidential because he's just a goddamned bum, you see.

But, sometimes, I think the media is worse:
As Washington braces for this week’s expected vote to impeach President Donald Trump, partisan battle lines hardened on Sunday, with Democrats defending impeachment even if Trump isn’t removed from office and Republicans denouncing the integrity of the constitutional process.The Democratic-controlled House planned to vote Wednesday on two articles of impeachment against the Republican president, and the decision whether to make Trump the third U.S. president in history to be impeached was expected to play out along party lines. There is some d…

Spoiler Alert

Tulsi Gabbard is going to work very, very hard to re-elect Trump:
Tulsi Gabbard has been slowly edging toward leaving the Democratic Party and, it now seems more likely than not, launching a spoiler candidacy to peel disaffected left-wing votes away from the Democrats. Her “present” vote on impeachment, followed by a disavowal of what she called the “zero-sum mind-set the two political parties have trapped America in,” sets the stage for Gabbard to play the role of 2020’s Jill Stein.Left-wing anti-anti-Trumpism played an important role in the bizarre 2016 outcome.Die-hard Bernie activists, fired up with anger at the release of DNC emails stolen by Russians that purportedly showed the party had rigged the primary, demonstrated against the party outside its convention hall and tried to drown out the speakers inside with boos. Stein attacked Hillary Clinton from the left, then audaciously staged a grift-y fundraising scheme supposedly to hold recounts in the states she had labored to flip…

Trump Will Burn it All to the Ground

It is difficult to see how the latest war in the Middle East will end. I don't have any answers, and, really, no one else does, either.

Here's what people should pay attention to--this happened just as evidence of Trump's orders to the Department of Defense landed on the front page. This happened after the major holidays and just as we are beginning the 2020 primary season in earnest on the Democratic side (the GOP has decided to prevent another Pat Buchanan moment, circa 1992, from happening).

Every life that is lost is because of Trump's decisions.

Every penny that this increases the price of gas is a tax on the poor and allows people who regularly have access to Trump to maximize their profits.

Every American traveling overseas is less safe.

Everyone who cares about peace will be shouted down and marginalized because that is the media's job.

Every attempt to hold Trump accountable will probably fail because the GOP is complicit in all of his crimes.

Everyone ch…
