Resolution
*Warning: Take backups of any files prior to modifying them. Ensure the backups are in a location that will not be overwritten (i.e. the Desktop).

The citect.ini file contains the path to where the alarm index is saved. See the example below:

[Alarm]
CacheLength = 2500
IsolationDetectIP1 = 172.18.32.1
IsolationDetectIP2 = 172.18.32.23
SavePeriod = 600
SavePrimary = D:\ProgramData\Schneider Electric\PowerSCADA Expert\v8.1\User\Stennis_Main
SaveSecondary =
ScanTime = 500
Sound1 =
Sound1Interval =
Sound2 =
Sound2Interval =
Sound3 =
Sound3Interval =
SummaryLength = 5000
SummaryTimeout = -1
UseConfigLimits = 1

The save primary gives the location of the alarm logs. In that folder there will be two files named: projectname_cluster#_almindexsave.dat and projectname_cluster#_almsave.dat.
Removing those files and restarting the project will clear the alarm log data.
