@patton_cascadia I am currently refreshing some of the sea level stations in the area on the IOC repository; nothing so far but still watching.

Did you feel it? Here are the waveforms from this afternoon's M3.8 in western PR. For more information see: https://t.co/BvK2ZliC9G

Rapid map and waveforms from this evening's M5.6 Northwest of PR. The earthquake is near the northern tip of Mona Caynon; I will need to run a focal mechanism tomorrow.

@SeisLOLogist @SeismoSocietyAm Unfortunately I won't be there this year but I will send my grad student to come say hi.

@SupportRequests @Support FYI your bot did not recognize my verification tweet and the X system no longer recognizes my phone number as valid (aka can't receive text). Any way to get help adding my email to recover/change my password?

SSA is offering a special two-part course on 2 and 4 April on how to title and open a great presentation, led by Temblor CEO and Stanford instructor Ross S. Stein. The course is free to SSA members. Not a member? Join SSA today! https://t.co/4yNJdskxfl

Map and record section of this morning's M4.45 earthquake in SW PR. My computer is quietly running a Bayesian inversion of the focal mechanism (aka will be calculating many Green's functions for the next few hours).

@geosmx @theAGU Access? The AGU travel grants my students (all underrepresented in geoscience) qualify for don't even cover the air fare cost. The AGU meeting is flat out inaccessible to many of my students now.

Finally the NA/SA plate Boundary reference: Bird, P. (2003) An updated digital model of plate boundaries, Geochemistry Geophysics Geosystems, 4(3), 1027, doi:10.1029/2001GC000252. (9/9)

Warning Scientist handwaving! Looking at the July 10 M6.6 my current interpretation is that it is likely an infrequent earthquake occurring along a pre-existing structure in the NA plate. The USGS mechanism aligns well with structure evident in the free air gravity anomaly. (1/9)
