#EarthquakeReport #EarthquakeToot for #OTD in 2018 M 6.7 earthquake

along the Jan Mayen transform fault offshore of #Greenland and #iceland

along the Mid Atlantic Ridge plate boundary between the North America plate and the Eurasia plate

#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:

#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

see the magnetic anomaly maps
