The Types of Geologic Fault Lines in 99 Seconds

Earthquakes are primarily triggered by fault lines. However, there are multiple types of fault lines which move in different ways. This video will discuss the main types of fault lines, including strike-slip, normal fault, reverse fault, and oblique faults.

I hope there are more of these little geology basics videos on the way.

[jrkorman]

Excellent - I like these little "back to basics" type of videos. Please continue to do the same with of the more common geology nomenclature

[whiteknightcat]

ALL of these faults have one thing in common ... none of them are MY fault!

[FirefuryAmahira]

Ah, the Northridge thrust fault. The one that taught a whole lot of Los Angeles residents the term "blind thrust fault." Good times! Loving these "-in 99 seconds" geology basics vids!

[xwiick]

Thanks for all the hard work on these videos.

[briankepner]

Thank you I thought it was much more complicated than that actually thank you for making it simple

[rickkearn]

Very cool new type of video, GH! 99 seconds...great idea. Thumbs up.

[scrappydoo]

You have been doing an excellent job on the short duration basics vids geo hub 👍
I hope you do more

[LadyAnuB]

GH,
Thank you for this video. I requested this one some time ago and you've come through!
For your section on creep, you can use the Hayward Fault for that. There is a long section in the East Bay that has had this happening for 100+ years. Memorial Stadium on the Cal campus had to have repairs done to it thanks to this creep on the Hayward Fault and there are plenty of other spots where this creep shows.

Nice, quick and informative video. Thank you, Sir.

Thought this was a repost, whoops.

You gonna cover Etna tomorrow GH?

[ausnorman]

So not to be difficult but, if you're standing on a the fault @1:11 if you pin 180' then how do you determine if its a right or left fault?

[psalmerperena]

Is it possible for the Main Himalayan Thrust to produce a magnitude 9 earthquake?

[tomolson]

Now there's a shift, it's really nobody's fault!

[NonnoNao]

Looking forward for an update on Etna and Stromboli

[ThomasWLalor]

And the crack of Dawn ?!?? Whose fault is that??!! (Earthy humour)

[BlackCloudCV]

Thank you for teaching geology centered content. I have a question. A right or left lateral strike-slip fault "When viewing along the axis of a strike-slip fault if the righthand side is moving towards you, it is a right lateral strike-slip fault..." if two observers are both looking at the same fault, 1, 000 feet apart, and facing each other, one would see a right lateral while the other would see a left lateral. Which observer is right?

[bothewolf]

Meanwhile Etna is belching her guts out XD #Timing

99 seconds...
this was well over a minute...

[PlayNowWorkLater]

It’s your fault that I know more about faults.
