Cluster of 3 sassy stratovolcanoes in central Oregon with 3 very different personalities. Known to be heavy breathers. Part of a local gang of 450 volcanoes.

#CautionMayContain silicic magma capable of producing a large explosive eruption in the near future!
Unlike @MtStHelensWA, @MountRainierWA @MtAdams321040, @MountShastaCA or @MtAdams321040 which only contain intermediate magma at best & could never produce big explosive eruptions!

On Sunday night, I was featured in the Volcanoes episode of the new @CNN documentary "ViolentEarth". The documentary is very well-produced and focuses both on survivor stories and the science of volcanoes!
It was a great experience! 🌋🤓
Here is a clip:

Welcome back from your slumber, Mauna Loa!🌋
The last time you erupted (1984), Prince's "When Dove's Cry" had taken over the world
Last time I erupted (~1 AD) the Principate of Rome had just taken over the world. Ahhh how time flies!
Maybe I'll join in w/ an eruption!

You can clearly see the "unzipping" of the fissure from right to left starting at 0:09 (after the fog clears). The fissure is a linear crack from which the lava flows (seen as a hot, yellow line in the thermal image)

This short video shows thermal camera footage of the onset of the #MaunaLoa eruption from the volcano's summit. The temperature in degrees C is shown by the colored scale bar on the right. For additional information visit: usgs.gov/volcanoes/mauna-loa… #MaunaLoaErupts

VANCOUVER! VANCOUVER! THIS IS IT! At this moment 42 yrs ago, (May 18, 8:32 am), a M5.1 earthquake triggered the largest recorded landslide, causing eruption of @MtStHelensWA
The eruption produced a 670 mph lateral blast, pyroclastic flows, deadly lahars, & ash that circled the 🌎 – at Nashville, TN
#OnThisDay 42 years ago, @MtStHelensWA erupted and became the UGLIEST volcano in the Cascades! The eruption reduced her summit by 1,314 feet and left a 1 mi wide horseshoe crater scar.
That ash-hole killed 57 humans that day! Despicable!
El Chichon erupted 40 yrs ago today...
Some of us are just a bit more gassy than others... its nothing to be embarrased about! Seems like the humans could use a bit of global cooling from a volcanic eruption right now.... I will see what I can do😉

#OnThisDay 40 yrs ago, the worst volcanic disaster in Mexico's history.
After 600 yrs of dormancy, El Chichón volcano erupted explosively, producing a Plinian ash column > 27 km high. This + eruptions on April 3rd and 4th destroyed 9 villages and killed over 1,900 people (1/3)
@GlacierPeak and I are the only Cascade volcanoes that erupt sticky "rhyolite" magma capable of producing huge explosive eruptions.
We're in the top 15 "Very High Threat" volcanoes list.
Yet, Glacier Peak only has ONE SEISMOMETER! Have some respect, humans! Before it's too late!
Here's a recent NEWS story. Excellent use of click-bait saying that @GlacierPeak is at a "very high threat" of erupting, although it has had that designation since 2005, and there is no new activity.....
UNLIKE ME!!!

Curious about how the scientists at @USGSVolcanoes ranked the threat levels for US volcanoes?
They used a 24-part scoring matrix based on: history of explosive eruptions, potential hazards, eruption recurrence, and nearby population.
Here's the report:

The USGS has detected new uplift at South Sister volcano (image USGS) using satellite radar & GPS. This looks like a continuation of uplift observed between 1992-2020 & does NOT mean eruption is imminent. Uplift likely represents deep intrusion of small amounts of magma at depth.

WE'RE BACK, BABY! Do not anger us, humans!
Scientists have detected ~1 inch of ground uplift near South Sister since August, which likely results from magma pulses 4 mi below! (Don't freak out yet, humans. The USGS scientists are closely monitoring our activity)
#CVO researchers detect subtle increase in the rate of uplift, 3 mi west of #SouthSister volcano, of #ThreeSisters in central Oregon. Episodes uplift observed in this area before. Volcano status unchanged. 1/6 volcanoes.usgs.gov/hans2/vie…

#OnThisDay in 1914, Sakurajima #volcano in S. Japan has a large VEI 4 eruption, Japan's most explosive eruption in the 20th century. It produced a 15 km ash cloud that buried the surrounding area (see pic I took of the buried 3-meter Torii, a traditional Japanese gate)

You've heard of the Continental Divide, but have you heard of Triple Divide Peak, MT?!
If a raindrop falls to the:
North- it will flow 3,094 km (1922 mi) to Arctic Ocean
West- it'll flow 1,915 km (1190 mi) to Pacific Ocean
SE- it'll flow 5,825 km (3620 mi) to Atlantic Ocean!

#OnThisDay in 1580, Spanish Conquistadors observe Galeras volcano (Columbia) erupt explosively, the 1st historical account of Columbia's most active volcano.
In 1993 tragedy struck when 6 volcanologists, attending a science conference, were killed when it erupted unexpectedly!

Can anyone provide advice on preparing a successful IODP participation plan/ application to sail?
Most overrated lake: YOU @LakeSuperior
