August 9, 1173, construction of the tower of #Pisa begins. Unfortunately, 5 years later the yet unfinished building starts to tilt as it unevenly compresses layers of mud and sand beneath its foundations. But its inclination may explain why it survived 600 years of #earthquakes.

A good reminder: Disaster preparedness is certainly important, but post-disaster recovery planning, including waste management, is also important (but often overlooked).

This Temblor article indicates that among U.S. states, WA is better prepared to deal with post-disaster waste management.

@BakerRL75

I make lists(=) too. Points to columns on #Fedilab for #Seattle #earthquakes =local etc etc. I have been getting & still have email notifications for 20 some years from the #USGS for all earthquakes in the world over 5.0 and more local over 3.5. I see the earthquakes, but *scans earthquake column* ... I have yet to see anyone say "omg I just felt an earthquake. Anyone else feel that??" +vids like the social media platform that's been destroyed and it bums me out. Bad.

In a new Temblor blog post, University of Texas Institute for Geophysics postdoctoral scholar Alice Turner details the various seismic risks Portland, Oregon faces from local faults and the offshore Cascadia Subduction Zone.

From Dave McGarvie:
Oct 2021 drone pic & old captions showing prominent subglacial basalt peak of #Keilir (right) around which many recent #earthquakes are clustered. Keilir is near the NE end of the SW-NE magma-filled dike, and is a likely location for an eruption.

@dansup @Gargron case in point, just a few tags that aren’t in trending that are doing trending numbers #news #f1 #formula1 #dogsofmastodon #earthquakes and that was just a few based on my interests of the morning.

Another question the kids may ask.

Why earthquakes happen all the time in Britain but not in Ireland

I lived in the UK until I was in my 20s and never felt an earthquake. However in New Zealand I have lost count.

Natural disasters such as #storms, #earthquakes and #wildfires are widely recognized for their devastating economic impacts. A new study released on March 17, 2023, revealed that #biological #invasions from #invasive species are as economically devastating as these more well-known phenomena... #water https://www.watercanada.net/new-study-shows-biological-invasions-from-invasive-species-are-as-costly-as-natural-disasters/

June 4, 1889, birthday🎂of German-American geophysicist Beno Gutenberg. He helped develop the Richter scale for measuring #earthquakes & studied Earth's interior. The Gutenberg-discontinuity - Earth's core-mantle boundary - was named after him.

#Dams have stoppered nearly 2/3 of 🌎’s major 💦systems, devastating their #ecosystems
✅ Displaced millions of 👨‍👩‍👦‍👦 many from Indigenous societies shattered by forced resettlement
✅ Adversely affected the livelihoods of 1/2 a billion people who relied on 🌱& #animals that no longer thrive
✅ Shifted so much weight geophysicists believe they’ve slightly altered speed of 🌎’s rotation, tilt of its axis & shape of its gravitational field! 😳
✅ Triggered 1000’s of #earthquakes

#WeCanDoBetter !

Geonet's seismometer near #Porangahau was somewhat overwhelmed by this morning's M5.9 and M5.4 #Earthquakes
The recording is sped up 48 times.
The square box formed by the trace is the mass in the seismometer hitting it's mechanical stops.
The #aftershocks continue.
