Is there any literature on ground motion studies of the 2002 Denali earthquake?

Mark Tingay

Hi Chenna,

Not sure if these help. But, there are lots of studies of ground motion on this earthquake.

Good luck,

Mark

Dear Mark,

Thank you for your information. I need what could be the ground motion record at the location of maximum horizontal slip (8.8 m) occurred along the Denali fault.

Yes, you can read the paper:

The recordings at PS10 in all 3 directions (2 perpendicular horizontal components and 1 vertical component) are available from the PEER NGA-West2 Ground Motion Database. You can set up a free account and access the records. The M7.9 Denali earthquake recording at PS10 is PEER record sequence number (RSN) 2114, so you can get the record you want easily (just search for RSN 2114). As you say, this recording has an estimated Rrup of 2.74 km, but an estimated Rjb of 0.18km. You might be able to use a ground motion prediction model and tweak the input parameters to approximate PS10 intensity, then use all the same parameters except R=0 to estimate intensity at the fault.
