I wrote a new tutorial on how to combine iOS lidar with Structure-from-Motion photogrammetry to make accurately scaled #paleoseismic trench logs. 🚨🚨🚨 🧵

I wrote a thread about Mastodon on Twitter, it needs to be read.

Our new paper on EPS!!
Short-period OBSs and CMT inversion using a 3D model revealed the aftershock activity off Ibaraki after the 2011 Tohoku earthquake.

I feel, as part of my initiation into this space, I must talk about my love of #Medieval elephants.

Yes, you heard me. You see, though bestiaries were very common in Western Europe, elephants were not.

So things like this happen.

"SO... lion body... got it, cloven hooves, okay, big ears and dead bird eyes... long snake face... PERFECTION."

Space Station Flyover time-lapse movie. I captured 163 photos of the ISS flying over on August 4th. Here's a movie of them:

If you download your Twitter archive it arrives wrapped as a static HTML page, which is not very useful for doing anything with, and worse: it requires the original account to be still active to do useful things like enlarge the images since they use t.co links.

So here's a Python script to convert a Twitter archive to markdown or other formats: https://github.com/timhutton/twitter-archive-parser

Now you can archive your tweets in any way you want.

Large earthquakes in #Canada??
Not so often, but yes, some of the world’s largest #earthquakes, including:
M9 (offshore #VancouverIsland in 1700)
M8.1 and M7.8 (offshore #HaidaGwaii in 1949 and 2012, respectively).
More than 4000 earthquakes are located across Canada each year, from coast to coast to coast.

I THINK SOMEBODY JUST FEDERATED MY TOOT

TIL that you can mute accounts for different durations of time, starting at 5 minutes.

Such a thoughtful feature — it understands that sometimes you want just to step away from someone's subject du jour, even if just for your current session. Takes some of the hostility out of the act of muting.

#Mastodon #MastodonTips #TwitterMigration

#Feditip #Newhere #Twittermigration for those new here, be aware the trolls from Twitter are starting instances to try and attack us with. When you get tagged in by said trolls, DON'T ENGAGE! Report them using the tool, THEN name/@/server.instance <- like that rather than tagging them. Also tag in #Fediblock so the various admins monitoring know to block the full instance if it's a troll farm. Do your part right to keep this community going strong!

Initial impression of Mastodon…

A lot of #earthquake activity today. There was a magnitude 7 south of #Fiji this morning. Thankfully deep (650 km) so not dangerous. Notice how there are no surface waves. This is the signal from IU.CTAO (Charters Towers, Australia) - I think we see P, PP, S, and SS (where PP and SS are surface returns) - do you think? Data via IRIS!
