	Abstract = {We used the joint hypocenter determination (JHD) method
to relocate 3611 crustal
earthquakes that occurred from 1988 to 1999 in central Alaska. The new
earthquake locations provide
more details on the structure of the Kantishna cluster and better
locations for the aftershock
sequence of the 29 November 2000 M-L 5.6 earthquake in the Minto Flats
seismic zone. The JHD
locations for the aftershocks of the 1995 M-W 6.0 Minto Flats earthquake
and 22 October 1996 M-W 5.8
earthquake near the Denali fault are also available. A catalog, of 196
fault-plane solutions
consisting of the moment tensor solutions for the earthquakes with
magnitude 4.0 or above and P-wave
first-motion solutions for the earthquakes with magnitude 3.4 and above
that occurred from 1988 to
2000 was composed. Moment tensor solutions were calculated using
regional broadband data. This
catalog was used to calculate principal stress orientations in the
crust. The stress orientations
change across central Alaska. In particular, the maximum principal
stress orientation rotates
clockwise from SE-NW to SSW-NNE direction as one moves from west to
east. These stress orientations
are consistent with the stress field transferred from the plate
convergence in southern Alaska. In
addition, we tested different velocity structures in the moment tensor
inversion procedure to
identify velocity models for calculating the Green's functions. The
moment tensor inversion study
shows that it is possible to obtain a reliable moment tensor solution
for moderate-sized earthquakes
(M-L greater than or equal to 4) using three-component records from a
single broadband station when
the epicentral distances are between 50 and 300 km.},
