Quickly plotted the rough location of the 2025 Mw8.8 Kamchatka earthquake (USGS hypocenter) on Figure 1 in Pinegina et al. (2018). It would be interesting to know:

1. Did the 2025 event re-rupture the northern rupture of the 1952 Mw9.0 event?

2. Did the 2025 event rupture across the "segment boundary" at ~N53?

Random find in a "forgotten" filing cabinet, no clue about who wrote it or when. Any idea? Let us know...

Di Giacomo et al. had a fresh look at the time-dependent uncertainty related to early analog instrument picks. Their findings translate into a more reliable location uncertainty estimation. @ISCseism
