#EarthquakeReport #EarthquakeToot #TsunamiReport for M 7.3 #Earthquake near Tonga Trench
Here are the plots for gages that the PTWC listed as having #Tsunami waves
Pago Pago record is clear, Nukualofa record is more noisy (is it a tsunami?).
Note the difference in scale on tsunami size axis (on the right)
updated these to the report

#EarthquakeReport #TsunamiReport for M 7.3 #Earthquake Tonga trench
I missed this since the gage is on the nodal plane for the earthquake. BUT there was a #Tsunami recorded on the Pago Pago #AmericanSamoa tide gage.
Here is a screenshot

#EarthquakeReport #EarthquakeToot for M 7.3 #Earthquake near the Tonga trench #toottoot
thrust (compressional) earthquake along the outer rise
no #Tsunami observed on tide gages
report here includes my interpretation and a regional tectonic summary:

reverse (compressional) mechanism
south of analogues incl tsunamigenic 2009 M 8.1 (tho that was extensional)

#EarthquakeReport for the M 7.6 (likely) subduction zone #Earthquake in #Mexico on 19 Sept 2022 #TootToot #toot
catching up on reports that happened after my website went down
generated 0.6-1.7m wave height #Tsunami
probably triggered landslides/induced liquefaction
report (and higher resolution figures) here:
https://earthjay.com/?p=10472
#EarthquakeReport for M 6.9 #Earthquake in Taiwan on 18 September 2022
there was lots of damage and some casualties :-(
landslides and liquefaction models show that there was a high likelihood for these.

i am filling in some #EarthquakeReport #Toots as I just got my website back up and running after almost two months of arduous work (steep learning curve getting web services set up on a robust server)
Greetings tooters!
this account is for Dr. Jason "Jay" R. Patton (aka EarthJay) and I march for science. #hashtag #Introduction #MastodonIntroduction
His main education/outreach effort is voluntarily writing up #EarthquakeReport posts on earthjay.com. These are for #earthquake and #tsunami events of interest, sorted in different ways; sorted by year here: https://earthjay.com/?page_id=3220
they are an engineering geologist (PG license 9758) who serves the public while at the California Geological Survey, Seismic Hazards and Tsunami programs. https://www.conservation.ca.gov/cgs/
he has been studying the tectonics of the Cascadia subduction zone (a convergent plate boundary fault system) for over 25 years (MS thesis at cal poly humboldt, dept geology). he is an adjunct professor at this dept. https://geology.humboldt.edu/
they studied marine sedimentary records (submarine landslide deposits called turbidites) of earthquakes offshore of Sumatra/Cascadia for my marine geology & geophysics PhD at oregon state university. https://ceoas.oregonstate.edu/
capital letters are over rated but chocolate and oxford commas are not.
#EarthquakeReport for M 6.0 #earthquake in northeast Pacific
unclear about how this relates to the Murray fracture zone
the tectonics south of the MFZ are complicated
