Thread on the Contentious Communication session at #GSA2019
Our 1st speaker is @honu_girl from the Geological Survey of Alabama speaking about communicating #earthquakes to the public.

“Part of being a voice for science is being yourself” - Dr. Hill
Alabama has oil shales! This alarmed the citizens, in part because of incorrect media articles.

@honu_girl corrected misinformation, held public meetings and gave the citizens agency to make their own choices.

“What does your audience need? What are their concerns?”

#California #earthquakes hit dead center of the China Lake naval military weapons base. One of the most secretive bases! I’m highly suspicious! Perhaps it was NOT a natural EQ! Something far more nefarious might be going on! Comments from the China Lake FB page!
Check out this article on Tiger Woods regarding his military father and the China Lake naval military CIA weapons base, the epicenter of the #californiaearthquake! He just might be an MKULTRA mind control victim! LINK:…

Another earthquake. 7.1 from @USGS 11 miles from Ridgecrest. Here in south Corona, hanging items are still moving.

Hope all are safe.

Downgraded to 6.9. The 6.4 was a foreshock. @DrLucyJones knows her stuff. You want to know anything about #earthquakes SHE IS THE ONE TO LISTEN TO!
Aaaaaand upgraded back to 7.1.

I don't usually all-caps but I'm going to. NO ONE CAN PREDICT EARTHQUAKES. We just can't do it. The difference between a prediction and a forecast is essential. We (scientific community) *can* forecast aftershocks--quakes that come after a mainshock (main earthquake). See link:
Prediction: Say the time, place, magnitude (when, where, what/how big). We *cannot* do this for #earthquakes. If someone claims to know any of these three things, it is unfounded.
Forecast: Probability. We *can* do this, to an extent, and are working to get better. How likely is an event? We can use math for that. ... But nothing is certain.

The Great Alaska Earthquake occurred on March 27, 1964 and rocked the state with strong ground shaking that lasted four and a half minutes. #AlaskaEarthquake #earthquake
At M9.2, it was the 2nd largest quake ever recorded. This event also rocked the scientific community by confirming a major principle of #platetectonics with the observation that the oceanic Pacific Plate dives beneath the continental North American Plate at the Aleutian trench.
On average, #Alaska has 24,000+ measured earthquakes every year. Usually, there is at least one M7 every year. Between 1899 and 1986, eight #earthquakes of M8 or greater impacted different areas of the Aleutian subduction zone.

Subduction-zone mega-thrust #earthquakes, the most powerful earthquakes, can produce #tsunamis through a variety of structures that are missed by simple models. (THREAD)
The basic model shows rock above the convergent plate boundary being compressed and bent as it stores elastic energy. Once friction is overcome, the overriding plate slides abruptly up the fault causing the leading edge to heave seawater upward generating a #tsunami.
In 2011, the M9 #Japan #earthquake ruptured a fault area 500kms x 200kms over an interval of nearly 3 min. Surveys of sea-floor bathymetry before and after the earthquake document up to 50 m of fault displacement at near the Japan Trench.

Hi @GlenPhillips and @ToadWetSprocket! You asked me a question about #earthquakes in the PNW at one of your shows DC in Aug (that’s me in the @500womensci shirt). I’ve finally got a more complete response for you! (THREAD)
The Pacific Northwest is a region of high #earthquake risk because of megathrust earthquakes on the plate boundary, deep earthquakes within the subducting plate, and shallow crustal earthquakes.
Along the western edge of the PNW, the Juan de Fuca Plate dives beneath the margin of the North American Plate in a process called subduction. On Jan 26, 1700 a M9 earthquake ruptured the full 1,000 km length of that plate boundary.

Japan has more measurable #earthquakes than any other country. This is because #Japan is wedged among four major tectonic plates. (Thread)
80% of earthquakes worldwide occur around the circum-Pacific region chiefly along the subduction-zone boundaries, known as the “Pacific Ring of Fire”, so named because of the more than 400 active volcanoes that occur there.
The earthquake and volcano belt sweeps through Japan where about 20% of worldwide measured earthquakes occur. There are more than 100,000 earthquakes recorded in Japan every year. Of those about 1,500 are strong enough for people to notice.

So here are my extended thoughts on the #KenyaCrack, or #KenyaGully if you prefer. The narrative that’s going around is that this is a great gash that opened up and is splitting Africa in two. That's incorrect. Africa is being split but very slowly. This is called rifting.
Riting is definitely happening in Africa. This is not really disputed. There is lots of scientific literature on the subject.…
But rifting occurs over a very long period of time, like millions and millions of years.
Rifting progresses through earthquakes and volcanic eruptions and other geologic forces. Here is an animation showing how the crust thins before it splits. (This example is from the US, but the process is similar)
