Because seismic waves are slower than internet signals, it’s possible to send an alert after an earthquake starts, but before the shaking reaches you. A few seconds’ warning is enough to pull over to the side of the road, climb down from a ladder, step away from a high shelf or window, put down a scalpel, etc.

Mexico and Japan both have systems like this, and Los Angeles has launched a pilot program with apps for both Android and iOS.

Somehow this year has just gotten away from me as far as posting general photos. Oh, I made sure to post albums from events like comic conventions and hiking trips. But the random one-offs and two-fers? I’ve been tossing them up on Instagram, Pixelfed, and/or Mastodon, but I haven’t been maintaining my Flickr gallery.

Part of that is just that this has been a weird year. Part of it, I think, has to do with unexpectedly replacing my phone back in February when my previous phone died without warning. (Almost everything was backed up, at least.)

Whatever the reason, I’ve got eight or nine months of random photos, some just barely interesting enough to share, some really good (IMHO), that I haven’t been curating for Flickr. And the longer I go without posting them, the less it becomes a cool thing to do and the more it becomes a Task To Be Done.

So I sat down tonight after putting the kid to bed, hooked up my camera and my phone to my computer, and started moving and categorizing photos. I eventually got tired of it, but I freed up a lot of space. Even though I’m not quite done with that stage, I went through all the photos I’ve got so far and picked out the ones I want to highlight.

There are enough that I’m breaking them into categories to upload in small batches over the next week or two. If you upload more than three at a time, Flickr will only show the most recent three to your followers. Hopefully they’ll be interesting enough to convince them to click through to the rest of the batch, but I’ve noticed that the top three in a batch always get viewed more than the rest, and always get more feedback. A lot of the more serious photographers I follow won’t even post batches bigger than two or three at a time.

The first batch went up tonight: It’s Los Angeles cityscapes. Continue reading

The air has finally cleared up enough to see Downtown Los Angeles and the mountains. After several weeks of smoggy days, wildfire smoke, and occasional gloom, it’s nice to be able to see something other than a gray blur in the distance!

Also interesting: seeing how much the view changes from late afternoon to really late afternoon. These shots were taken at 4:22 and 5:52pm on the same day. Unfortunately I seem to have held my camera at two different heights, so the foreground jumps around, but the skyline and mountains are in nearly the same spots, and you can see not just different colors, but different details as the shadows move.

Hazy view of mountains with some snow on top, not much lower down. A city skyline is visible between the mountains and a canopy of trees and low buildings.

From yesterday: the first significant snow in the mountains above Los Angeles this winter, courtesy of last week’s storm.

Unfortunately, it’s almost spring. The weather has already warmed up again. Last week I was wearing sweaters and a medium jacket. Today I’m back to short sleeves, and I had to put the jacket away on my lunchtime walk.

And there’s not much of that snow left today.

KQED has some great photos of snow in the Sierra Nevadas after the same storm. That’s more important, as California depends more on the Sierra snowpack for water during the summer.

They’re expecting another storm to come through next weekend. I guess we’ll see how much snow we get. And how long it sticks around.

Smoke rises from Mt. Wilson above Los Angeles on Tuesday around noon. The wildfire has threatened the observatory and critical communications towers. Today it’s too hazy to see anything but the barest suggestion of the downtown skyline, much less the mountains behind it. Not that it looked quite this clear even on Tuesday – I ran the photo through auto white balance to make everything easier to see.

I’m reminded of the last time the mountaintop complex was threatened by fire, during the 2009 Station Fire… and the photos I scanned from a 1992 tour of the observatory, wondering if that had been my only chance to see it.
