1. Hello Radix’ers, @akgungor_c here. I’m glad to be with you this week. It will be a pleasure for me to post here. My thing is to generate and “mobilize” information & knowledge to assist organizations and communities with respect to emergencies & disasters.
2. An eternity ago, I defended a Ph.D. thesis in political science in which I had mainly focused on #disaster and #sociopolitical #change. At that time, I thought I would not spend a single more minute on that text but instead leave it to collect dust in the French archives.
3. And after I walked away from academia, I literally forgot about it for a long period, until a couple of years ago. In fact, I’m catching myself -more and more- thinking about some of the conclusions I had drawn back then.

#CVO researchers detect subtle increase in the rate of uplift, 3 mi west of #SouthSister volcano, of #ThreeSisters in central Oregon. Episodes uplift observed in this area before. Volcano status unchanged.  1/6 volcanoes.usgs.gov/hans2/view/not…
Between June 2020-Aug 2021, #satellite data show uplift of ~0.9 in (about the width of your thumb) over a broad area 12 mi in diameter, west of South Sister. On-the-ground GPS monitoring confirms, detecting ~0.2 in of uplift since Aug 2021. #ThreeSisters 2/6
Uplift has been occurring in same area for ~25 years. From 1995 to 2020, area rose ~12 in (height of 2L soda bottle) at its center. Current uplift rate is slower than max rate from past - but distinctly faster than rate observed before 2020. #ThreeSisters 3/6

The eruption is over but the ground is still shaking - there have been dozens of #earthquakes around the #HungaTonga #volcano (magnitude 4.5-5), continuing today. 1/3

#GoogleEarth #Tonga #earthquake
Many are likely due to slip on existing faults or fracturing of new ones due to changes in crustal stress caused by the eruption. Others may be linked to magma movement, although that usually produces a more persistent signal called #volcanictremor. 2/3

I haven't seen any focal mechanisms for these events, which would tell us more about the type of #earthquake - it may be difficult to extract that information as these events are M5 or less, and seismic networks are sparse in this region. 3/3

Oh, cool!

Stress is basically how much the rocks are being squeezed, and in which direction. If we can know that, and also know how *strong* the rocks are, we can estimate whether they will break.

But it's super hard to measure... 1/n
When rocks *do* break (#earthquake!), we can use that to estimate stress. If you know the direction of slip, you can do even better. This even works for earthquakes that occurred long ago, if they left scratches on the fault!

Or, if you have a lot of money and time, you can drill into the Earth and measure the orientation of maximum squeezing based on how the borehole deforms.

Ever look at global #earthquakes from the top down? The #NorthAmericanPlate and #EurasianPlate seem simple around the Atlantic - they're pulling apart - but if you follow that boundary across the pole to Russia, it gets weird and diffuse. 🧵1/4

#tectoplot Image
#Iceland provides a remarkable view of the plate boundary. Here, the plates are pulling apart over a #hotspot, so the spreading center is on land instead of at the bottom of the sea.

And just look at the result! Pictured here: #LakeThingvallavatn. 2/4

But follow that plate boundary past the pole and under the ice, and you find yourself in Russia. Suddenly the #earthquakes are scattered and the plate boundaries poorly defined.

There's actually a whole extra baby plate here - the #OkhotskPlate. 3/4

A long thread--Well, that was an interesting night. There was a powerful 8.2 magnitude earthquake around 10:15pm 75 miles south of Kodiak in the Gulf of Alaska which triggered a tsunami warning that included Seward, where I'm working on the boat.
I did feel it here. It felt like the wind rocking the boat, not violent at all, but it went on for a really long time. I got an automated safety alert on my phone around 10:25, followed by a call from Devany to evacuate a couple of minutes later.
I grabbed the computer, jumped in the truck, headed uphill out of town about 5 miles, and parked in one of the pull-offs on the Seward Highway by 10:35, which gradually filled up with other cars and motorhomes.

NITI Aayog Islands Development Project: Megathread
The project involves:
- Redevelopment and Industrialisation of #GreatNicobar
- Redevelopment into a Model City of other islands, starting with #LittleAndaman Island
ensciencopedia.com/2021/05/niti-a… [1/16]
PART 1: REDEVELOPMENT AND INDUSTRIALISATION OF #GREATNICOBAR ISLAND
- The project involves construction of an #airport, #port, & a transportation system
- #Galathea WLS was denotified for the project
- The WLS is known for being the nesting site of the #LeatherbackTurtle. [2/16]
The denotification of the WLS in January contradicted the National Marine #Turtle Action Plan (released Feb 2021) which declared the Galathea WLS as one of India’s few ‘Important #Coastal and #Marine #Biodiversity Areas’ and ‘Important Marine Turtle #Habitats’. [3/16]

Strong signs of a potential #volcano #eruption near #Keilir on #Reykjanes peninsula. Scientists reporting #earthquake patterns that are similar to the start of an eruption. Eruption likely to start within the next few hours. Image
The ICAO airport code for @kefairport and #Reykjavik airport have been raised to Orange - which indicates a high likelihood of imminent eruption. Rescue teams are being put on standby. Coast Guard @gaeslan helicopter to fly over the area shortly. Press briefing scheduled for 1600
This potential eruption is not expected to cause any damage to infrastructure and towns/cities according to @almannavarnir. The eruption has not yet started and is far away from habited places.

#Iran #Teheran #Earthquakes

-THREADE-

Technology for earthquake prediction has not been founded in the world yet. In Tehran, 26 seismographs have been deployed so far.
The mayor of Tehran, Pirooz Hanachi, hopes to install 200 more in areas around Tehran that are prone to earthquakes. Tehran is one of the most dangerous metropolis in the world. The planet is at risk of numerous natural disasters ,
such as earthquakes, floods , droughts, droughts, landslides and fires. And earthquakes following. Tehran has a population of over 8,300,000 people with a mixture of old non-resistant structures and new high-rise buildings.

The active plate boundaries around the Pacific Rim are fairly simple, but plate tectonics are more complicated where continents collide. The Alpine-Himalayan belt, which stretches from Europe to the Himalaya, comprises complex and distributed zones of faulting.
These faults are moreover mostly on land, creating a wide zone of high seismic hazard, the yellow-red swath in the map below. Image

The Philippine Institute of Volcanology and Seismology (Phivolcs) said on Monday that it was monitoring Mount Kanlaon in Negros Occidental province after it recorded over 130 earthquakes since Sunday.
The institute issued a statement reminding the public that Kanlaon Volcano remains on alert level 1, "which means that it is at an abnormal condition and has entered a period of unrest", reports Xinhua news agency
