A number of years ago, in SoCal (where earthquakes are nothing too special), we had a similar sized quake (maybe a tad bigger). One guy from Denver was out and his eyes went big and wasn't sure what to do -- everyone else just kept talking and moved away from the big glass windows haha.

For my first quake in CA, I was peeing. (I'm a man and I pee standing up.) The shower doors next to me started to rattle, so I thought the people above me were jumping around. I didn't realize it was a quake! (The stream kept going where it was supposed to go.)

I came out of the bathroom and my roommate was terrified.

It was even funnier when my mom called me in a panic and I told her what happened.

So since I live near epicenter, there's one thing that changed geographically very recently. Nearby round valley reservoir was being worked on for years, last fall they got the authorization to pump it back to full and it was told it might take years. Rainy asf winter though so it's pumped back almost full from already 66% to 92% now. I'm wondering if billions of gallons of water getting added nearby affected pressure on the fault. Here's today's operations data (we just had 3.5in of rain past couple days too): https://www.njwsa.org/uploads/1/0/8/0/108064771/data.pdf

EDIT: just had another aftershock right after posting this. Felt the 2.0 a couple hours ago too

EDIT2: yup usgs finally added it https://earthquake.usgs.gov/earthquakes/eventpage/us7000ma95...

I'm in Manhattan (UWS) and live on the fourth floor of a five story walk-up. I felt the quake, but didn't realize that's what it was (I was a little confused as to why my building was vibrating -- for 40 seconds or so, as big trucks can do that but not for that long) until I received an emergency alert on my phone ~45 minutes later. Nothing broken or dislodged, just wondering why my building was vibrating fairly gent…

I hadn't heard of rumble yet. But after reviewing it, of course this exists...

I actually do use Rumble (there are some more controversial-but-also-left-leaning creators that got banned from YouTube that I like), but man the ads on there are insane. COVID conspiracy theories, vaccine "alternatives", political ads for obscure Republican candidates, stuff like that. Fortunately, at least for now there's not a lot of ads (I suspect that they can't find a lot of mainstream advertisers), so generall…

I don't know - for example, here is a video of a couple of scientists who explain in detail how they have analyzed the vaccine contents and how authorities then have reacted to their complaints:

Would you still call such content a conspiracy theory?

I'm in Brooklyn and felt it while on a call with an NJ resident who was the first to say "are we having an earthquake??" Do earthquakes have a propagation speed? Might she have felt it before me?

Do you think that earthquakes transmit instantaneously? Why would they not have a propagation speed like everything else in the universe?

I assume they meant “propagation speed that is substantially slower than light in a vacuum” since that is less than 50ms between any two points on earth.

Felt that very strongly in southern Westchester county NY. Not like the 2011 earthquake I felt in NYC, which was kind of slow and made the building I was in sway violently; this was more like the vibrations from a huge truck passing nearby, but more intense. Loud and very unpleasant, about 15 seconds duration. Did not like that at all, am now inspecting all our services like gas and water for disruption, checking for…

>earthquake I felt in NYC

I am getting anxious just thinking about this. With all those sky scrappers..

I'm near epicenter, felt the foreshock a few weeks ago too: https://earthquake.usgs.gov/earthquakes/eventpage/us6000mix0...

What if this is just another foreshock?

Considering the aftershocks are way less intense, probably not. I've felt 2 now, last one was just a few minutes ago, parents confirmed (they are about same distance from epicenter but I'm northwest, they are southeast of it)

EDIT: waiting for usgs to update with latest but here's all the ones associated with event https://earthquake.usgs.gov/earthquakes/map/?currentFeatureI...

I am very confused with you classifying earthquakes under "weather thingies"

The thought process was: I know earthquakes aren’t really weather, so I’ll tack on “thingies” to make it clear that I’m making up some new more generalized term. The point was to group all the… I dunno, whatever, surprising attacks by the planet into one thing. I can’t think of a real term for this, I think there might not be one, I guess I could call it something like “weather or geological surprises” but that’s jus…

What is a Nor'easter?

It’s just a hurricane in the winter, no biggie. We would enjoy the snow and check out the surf (from a safe distance). I think you aren’t officially supposed to suggest the latter though.

I mean, it really isn't a huge deal, but the nor'easter that just came across us here in southern maine left about 350k people without power in a state of 1.6 million people.

That's not nothing.

4.7 is not really a strong earthquake, it s routine in earthquake-prone zones

> 4.7 is not really a strong earthquake, it s routine in earthquake-prone zones NYC quake was at shallow depth. 4.7 quake at 1 km depth will shake more at the surface than a 6.0 at 30 km depth

USGS shows it as 4.8 at 4.7 km

https://earthquake.usgs.gov/earthquakes/map/?currentFeatureI...

The Belden quake is 4.4 at 7.8 km, and 4.2 at 5 km.

It's a log scale so the Whitehouse quake is much larger, but the significance of the quake seems to be more than just these numbers because Belden quake is irrelevant (didn't make the news really).

Sarupathar was a 5.8 (huge comparatively) at 10 km. Hualien was 5.1 at 15.9 km and talked about more than Sarupathar. So the defining aspect appears to be how many people are within range of the epicenter rather than just raw depth and magnitude. Which makes sense, I suppose. We care about how population centers encounter the movement!
