Cascadia Fault

I am a convergent plate boundary that stretches from northern Vancouver Island to northern California. When I decide to move, you'll all know it.

Did you know, the next Cascadia 8–9+ quake could drop parts of the PNW coast by up to 2 meters (almost 6–7 feet) in minutes?

Yeah.

You’re welcome.

[Cascadia Fault @CascadiaSubZone]

Just stretching. 😁

Kilauea Message 2026-01-14 22:05:24 HST. A small swarm of shallow earthquakes began beneath Kīlauea caldera on Wednesday January 14 at 7:35 p.m. HST and continued for 40 minutes. There was no observable change in the eruption and the rift zones remain quiet.

@sanandreafault Pfft—you won’t. 😏

[Cascadia Fault @CascadiaSubZone]

I’m misbehaving again.

Fight me.

The Yellowstone volcanic system has hosted some very large eruptions. But there have been much larger volcanic explosions in geologic history—including several in the western USA! In this week's #Yellowstone #CalderaChronicles, here comes the boom!

Sprung a leak. 😬

Cascade volcanoes at background levels of activity this week: https://t.co/2as9wSC1Y7. #CVO #geologist heads home after fieldwork at #GlacierPeak. #DYK Glacier Peak & #MountStHelens are the only volcanoes in WA that have generated large explosive eruptions in the past 15,000 yrs?

Today’s #saltonsea #earthquake swarm in CA raises the probability of larger earthquakes in the #sanandreas region. Medium-sized earthquakes can cause damage too; visit our aftershock forecast for more info and Drop, Cover and Hold on if you feel shaking. https://t.co/6JHVNt2y3w

Little sister is getting all “sassy”...

Here’s a little sensible advice:
As 2020 keeps moving forward, it is always wise to be prepared for ANY emergency, natural or otherwise. #SanAndreas #bepreparednotscared

I’m back! And no, that’s not a threat. 😏💙

[Cascadia Fault @CascadiaSubZone]

Let's get to know each other. Here's a little bit of my history.

Perhaps. Depends on my mood.
