4.6 is really small, what's the actual news here? Was it strangely shallow or something?

Many of us on this website live in the bay area. The earthquake woke us up with a stern jolt and now you're witnessing a shared moment in the community as we try to drift back to sleep.

Over in Redwood City, I was woken up by MyShake, and we carefully felt for something, anything... but it was not to be.

Everyone is secretly (or openly) waiting for Teh Big One we’ve been promised for decades, when Western California will fall into the ocean and Las Vegas become a seaport.

This was the plot of a James Bond movie and when I was a teen I thought it was brilliant. Crack California off at the San Andreas- what could go wrong?

Same as Superman I -Lex Luthor steals a nuke to hit the San Andreas fault and turn Luthor's real estate into beachfront property.

Same. Been 12 years in SF and this was the strongest. We were awake as well so we felt the whole thing. I think I saw the walls move. Luckily it was short.

Contrast that with my experience in Ireland - 10 years and I heard thunder only twice, and saw a lightning strike only once. We sometimes get alerts due to some tropical storm that made its way up here, and the most we need to do is to collect our garbage bins and avoid biking because of the gusts.

This can't be true. We have thunder and lightning on a regular enough basis. The lightning is rarely of the fork variety though. And although the 'named' storms usually pass without much damage, it's not uncommon for people to be killed by falling trees etc. and large numbers of people to lose power. We're very lucky when it comes to lack of dangerous natural phenomena or animals but thunder is incredibly common.

There's no thunder in Ireland? Why?

There is. "In 2024, Ireland recorded almost 3,400 cloud-to-ground lightning flashes (lightning strikes), marking a moderately stormy year, but well below the exceptional year of 2023, which set a record with more than 9,000 cloud-to-ground lightning flashes detected."[1]

It's also worth noting that a mag 8 is about the maximum expected from the San Andreas fault, a strike-slip fault, and most quakes come in well under that. The two largest quakes I'm aware of, the 1906 San Francisco and 1857 Fort Tejon quakes, were mag 7.8 and 7.9 respectively. Significant damage can be experienced starting at about mag 6, though that tends to be pretty specific (individual structures, often pre-dati…

The Cascadia earthquake in January 1700 produced a tsunami that traveled all the way across the ocean and hit Japan with 16-foot waves. That's what mag 9 looks like.

Similarly, the Boxing Day tsunami in 2004 was from a 9.1 magnitude quake in Indonesia.

I live in Dublin. People say the weather is much milder here. I would expect the other coasts to be much, much worse.

I'm from Georgia where summer thunderstorms are extremely common and we had ones that were so explosive that candles would vibrate off the fireplace mantle. I moved to SoCal and i'm always amused when a small storm comes by once a year and people freak out. I miss those storms man. Nothing like sitting on the porch and watching them roll through

As we called it in Missouri: good sleeping weather. I can nap through a tornado, j tell you.

I grew up in São Paulo, Brazil. The thunderstorms there are GLORIOUS!

That's actually surprising to me. Being in the North Atlantic, I would have thought thunder storms would be common. I lived in LA for 5 years, and I definitely missed thunder and lightning. If I were going to space, I'd bring rain/thunder/lightning sounds to listen to like we've seen in sci-fi films even more so than the ones with cricket sound tracks.

I live in Dublin, which is shielded from the worst storms. Still, the weather patterns are not conducing to thunderstorms and lightning strikes average to around 10 per day over the whole island.
