Focal depth

[edit]

If a 102 km surface rupture was formed, would the earthquake's depth be 80 km as mentioned in the infobox? I came across a few papers with their proposed focal depth at between 10-15 km (another said less than 40 km) but none as deep as 80 km. In addition, if this was associated with Basin & Range extension, the event should have a shallow focus right?--Dora the Axe-plorer (talk) 02:55, 15 March 2021 (UTC)[reply]

You're quite right, that doesn't make any sense. Having said that, Solov'ev & Go (1975) give a depth of 80 km in their "catalogue of tsunamis on the eastern shore of the Pacific Ocean", which is used in the NOAA earthquake database here. I've removed it for now as that number has not been picked up by any of the many later journal papers on the earthquake, nor the ANSS comprehensive catalogue.
