Our analysis indicates that increasing pressure in the magmatic system, which far exceeds the change in pressure modeled as due to rainwater infiltration, was the primary driver in triggering the 2018 eruption.
For HVO, the smoking gun is found in the ground deformation record across a broad region of Kīlauea Volcano leading up to the eruption.
...
In summary, our consensus interpretation of HVO's monitoring data is that magma pressurization was the driving force in triggering the events of late April and early May of 2018.
No external process, such as rainfall, is needed to explain this.
But what about the rainfall hypothesis? While the role of groundwater and rain infiltration impacting the behavior of the volcano remains an interesting area of research, we know that extreme rainfall events have occurred many times in the recent past when no eruptions occurred, and the spring 2018 rains were no greater than many previous rainstorms.
Shipping might be a little high if you're buying just that, but they do will-call pickup in Oakland too.
It's good - it has a light fruit flavor, and has a bit of coffee tastes without being bitter.
0: Sweet Maria's is a great shop and resource for green coffee and roasting. If you drink even a moderate amount of coffee, roasting your own is pretty easy and pays for itself in a few months. If it sounds up your alley, skip the air popper and get a real roaster, though.
What Andy says is absolutely true. This machine learning class was easily the best class I took at Caltech. Prof. Abu-Mostafa got a standing ovation at the end of the course the term I took it. I wish I could have taken more of his classes.
It was also fairly difficult -- the assignments were hard, but at every step, you could look at what you'd done and say "I know why I'm doing this, and I can see how this works."
I remember at the end of the term he took several students' notes and made copies of them, so that he could compare the students' notes with what he was trying to convey, and could know if he wasn't teaching certain parts of the class well enough.
It's a shame that not all professors are as dedicated and responsive to their teaching obligations as Prof. Abu-Mostafa.
Oh, also, "introductory" in this context is meant to differentiate it from "graduate level". Every student (mostly juniors and seniors) in this class will have had several terms of math, theoretical CS, and practical programming classes.
I realized this morning that the post doesn't explain the original title of the piece. We got posted to SMBC, and someone re-tweeted Zach's awesome comment into Spanish:
"Estos chabones hacen CATAPULTAS. Con qué? CON LASERS. Por qué? POR LA CIENCIA http://kck.st/gj3byf
I was using it in a tounge-in-cheek way, but it didn't really come through in the title. I couldn't tell you what the difference is between "pivoting" and "starting over" either.
Except that if "starting over" discourages you, try "pivoting" instead!
