When you are driving through the mountains of obviously one of the highlights is …. a 3D printed concrete version of the white tower of Minas Tirith!

Looking over my photos from the Golden Gala in of I find that the audience reaction is sometimes even more entertaining than the actual achievement involved!

A fun evening at the Golden Gala in watching and taking lots of photos. started his comeback attempt, dominated her race, Italians loudly supported their athletes (and others) and there were some close races!

Nice view of Lake Como.
Oh yeah, and then a bunch of cyclists came flying by…

The SpaceX Dragon capsule that reentered the atmosphere on Saturday caused a sonic boom. I retrieved ground motion velocity data for seismometers throughout California & the N wave overpressure of the sonic boom generated a clear signal on most. Shown is an example.

East, North and vertical ground motion velocity time series for the re-entry of the SpaceX Dragon capsule recorded by a broadband seismometer in the Verdugo mountains, showing the N wave overpressure of the sonic boom. This is just an example, most Southern California seismometers show similar signals.

Spent a lovely day at the Tuscan coastline, thinking we should rent a boat next time

For more context on today’s M6.2 in the Sea of Marmara, a figure from Bohnhoff et al. (2013) shows the major North Anatolian Fault Zone segments with potential future rupture scenarios and their associated magnitudes. Today’s quake is located near the center of the Marmara segment.

Major NAFZ fault segments in the Marmara and Izmit regions in northwestern Turkey (simplified). Two potential future rupture scenarios and their associated earthquake magnitudes are shown reflecting the activation of the Marmara segment of the NAFZ as one single (∼7.4 M) or multiple (∼7.0 M) events. Green, orange/red and brown lines mark major fault segments of the Ganos 1912, Izmit 1999 and Düzce 1999, M>7, rupture zones, respectively. The Marmara seismic gap between the Ganos and Izmit zones has not experienced a similar sized event since 1766. The numbers between segment boundaries are observed time delays between the initiations of slip on consecutive segments. Question marks indicate potential segment boundaries beneath the Sea of Marmara.Historical seismicity map generated using GMT by Jascha Polet

This event may have occurred on the Marmara fault segment of the North Anatolian Fault, thought to present a significant hazard to Istanbul.
