Want to better understand EQ Data? Debi Kilb has some annotation for that...

IGPP Seismologist Debi Kilb annotated this ANZA network-generated image to better explain yesterday's Independence Day M6.4 earthquake in Ridgecrest, CA.

Final instrument recovery in Alaskan Megathrust complete

Director Constable and his crew are have successfully completed their survey and recovered each deployed instrument—with a bit of time to spare—and are returning to Seward along the scenic route.

SUESI sets a second record.

Congratulations go out to SUESI 1, and her doppelgänger SUESI 2, currently enjoying some well earned R&R aboard RV Sikuliaq. The instrument(s) followed up their own tow depth record of 5100m w/a new record of 5200m, collected data successfully, and have since been setting off a rather large number of alerts that indicate the instruments are bit battle worn.

Fialko co-chairing The Applications of Mechanics to Geophysics Symposium

Registration is now open for the Applications of Mechanics to Geophysics symposium to be co-chaired by Yuri Fialko and Xanthippi Markenscoff.  The two day event includes a international list of speakers and is open to the public. For more information, please click here.  A poster session will occur on the second day.  Registration is available here, those interested in presenting a poster should include their poster  in the respective box.

SUESI has a new tow depth record!

Congratulations to SUESI! She has beaten her *own* tow depth record by 100m. The EM lab's Scripps Undersea EM Source Instrument or SUESI recently recached a depth of 5100m while collecting data for the Alaskan Megathrust project. Read more about the data (and occasional coral) SUESI and her fellow instruments are collecting on Steve Constable's cruise blog here: https://marineemlab.ucsd.edu/Projects/Megathrust/

Sikuliaq drama, two OBEMs damaged, coffee supply meets crew needs

A bit of high seas drama over the weekend aboard R/V Sikuliaq. Two of the first six ocean-bottom (OBEM) instruments were run over the ship's thrusters during their recovery. While the instruments can't be put to use again this cruise, at least their data loggers were recovered. Not a complete tragedy in the Shakespearian sense, but a rough day nonetheless.

Costable's EM Lab, blogging from Alaska

Follow along as IGPP Director Steven Constable and his team travel to the Alaska Peninsula to collect data about how the regional transport and release of water impacts seismic activity. The first instruments were deployed last Sunday: https://marineemlab.ucsd.edu/Projects/Megathrust/.

HPWREN workshop highlights ALERTWildfire and "Virtual Fire Towers"

The ALERTWildfire network of cameras, some of which are hosted by HPWREN, proved effective in pinpointing remote, forested regions of Southern California fire locations in the summer of 2018. This success has fostered plans to broaden the network by creating "virtual fire towers."This success has fostered plans to broaden the network by creating "virtual fire towers." On April 24th, HPWREN co-founders Hans-Werner Braun (SDSC) and Frank Vernon (IGPP) workshopped with stakeholders and first responders at Palomar Obervatory to discuss the network deterimine its future growth.

Walter Munk: October 19, 1917 - February 8, 2019

It is with heavy hearts that we share the loss of IGPP's founder and first director, Walter Munk, who passed away Friday, February 8th.

Born October 19, 1917, Walter was an intellectual giant, and his pioneering research into surf forecasting, swell propagation, ocean currents, tides, time series analysis, ocean acoustics, and ocean temperature, along with his abundant prizes and accolades, will be remembered by many.  However, all those of us who frequented the halls of the Institute of Geophysics and Planetary Physics La Jolla will have a special memory of him.
