This did generate some beautiful/classic surface waves across the continent. My basement seismometer (Raspberry Shake) recorded it nicely.

I love you.

+1 if I was dating and had to create a profile with a list of ideals, seismologist would be listed. - totally serious. This stuff fascinates me. ‘My basement seismometer’ ....swoon....

Wait. Assuming that the posters responding are women, are we assuming Seimologist is a man? Seismologist, are you a man?

I am a man. All of the basement seismometers in NoVA are owned by men (I know who they are . The hardware is remarkably easy to set up. it is from https://raspberryshake.org. It costs a few to several hundred dollars. The device works remarkably well.

As for swooning for me, I never thought my PhD in seismology could be used to pick up women. In my generation, most seismologist were male (80+%), but today, about half of the grad students are female. I think this is great.

Fascinating! You were able to pick up the activity from Alaska here in NOVA? How often does your Raspberry Shake pick up activity?

Activity, all the time. Usually It is local clutter like cars/trucks hitting the speed bump in front of my house, our HVAC/Laundry, etc. Seismic events, about 1-2x per month usually.

sigh. he's married.....

and to follow up on this, what's up with the "my generation" comment.... I take that to mean you are not mid-career?

Mid 50’s.

I am from Southern California so when I think of seismologists I think of think of the amazing Caltech professor- a woman who was always on the news explaining the magnitude, epicenter, etc. Ask anyone from Southern California and they will know who I am talking about.

Lucy Jones!!!!! Right?
I’m from CA and know exactly who you mean. She’s super awesome.

Lucy is probably the best seismologist for communicating with the general public. It is not an easy skill. In 1994, after being woken up by the Northridge earthquake, she knew she needed to go to the office. But, she did not have child care (her husband is also a seismologist). So, she gave interviews while holding her child.

At the time, I did not understand how good she was in her role. I met her first at an AGU meeting in 1989; her poster was on the other side of the board as my poster (we were both reporting on the Loma Prieta Earthquake). She was friendly. Her work was more on human effects whereas I was looking at source complexity. As I have grown up, I have realized how important her role is. After a big earthquake, I am hyper, excited. She is calm. She makes people feel like everything will be all right. She is smart but also has a high EQ.

Seismologist, please tell that warming poster that earthquakes along fault lines are caused by tectonic plates shifting, not fracking and not atmospheric warming.

I already did. 0733 was by me.

You're a seismologist. Sure you are.


What you ARE is a global warming denier and a proponent of fracking and fossil fuels. Basically a useful idiot for the billionaires who are poisoning this plant.

That's what YOU are.

1) I am not a global warming denier, 2) Fracking has real issues.
But neither had anything to do with the Alaska Earthquake. Fracking only impacts within a few km of the the injection site. You only frack in regions that have shale, which can contain oil/gas. The rocks in that area are igneous and metamorphic. There are no petroleum products in southern Alaska. Therefore, there would be no reason to Frack there.

Similarly, there is no fracking in Central VA, as the rocks of he Piedmont are metamorphic. The people who do the fracking do it to make money. They are not going to do it in a place where they will not make money.

And earthquakes only may tangentially related to global warming in that in regions were large scale glacial melting (e.g., Greenland) will cause isostatic rebound (look it up, I do not feel like lecturing morons). At the edge of the of the rebound, a lot of stress and strain can accumulate, which can trigger earthquakes.

That is not what is happening in AK. In AK, the pacific plate is subducting under AK. The earthquake yesterday was the result of stress transform related to the subduction.

You deny the ice caps in Alaska are shrinking.

You're a fraud.

Alaska does not have a continental ice-cap (such as Greenland or Antartica Have). It does have ice fields and glaciers and the glaciers are retreating. The the Alaska seismicity were caused by ice melting, there would be similar seismic activity surrounding Greenland and Antartica, which is simply not happening. We can observe the subduction and the plate moments. Looking at the motion associated with the earthquake, you see the earthquake mechanism is consistent with a shallow normal fault under Anchorage. That normal fault system is why the Cook Inlet exists.

That PP needs to chill and leave the science to the grown ups.

Earthquakes happened before fracking and global warming...there are historical records of earthquakes going back for centuries.

Climate change is real, but so is plate tectonics and all that other geology stuff your boy is talking about. They aren't mutually exclusive.
