While there's no scan that specifically states "she was controlling and fueling it"
We know she was because that's what the bio blatantly suggests.
I mean,
if the Chaos Wave on panel revived Jaspers,
and Three separate bios are stating that,
Jaspers was revived by the "Scarlet Witch's Reality Warp"
What does that tell you?
Obviously that the Chaos Wave = Scarlet Witch's Reality Warp.
(Her Power in action)
.....................................................................................................
But I guess these scans might add to that a bit:
(These scans are from the very beginning of HOM)
Here Roma speaks about Wanda's initial Warp which was Global:
(It then spread across the 616 Universe and warped it into Reality 58163)

We are witnessing a Trans-Temporal Tsunami (Chaos Wave)
Originating from Earth 616"
.....................................................................................................
The definition of Originate is "Have a specific beginning ... Create"
.....................................................................................................
Roma knows it's coming from 616 (where coincidentally Wanda is)
but she doesn't know what's actually causing the Wave:

"The localized affects are so severe I am unable to ascertain the cause"
.....................................................................................................
What she does know, is that it's a "Chaos Wave" and,
it's expanding through a "Breach" withIN the 616 Reality:

"Until the Breach itself is sealed, this Chaos Wave will keep expanding"
"Chaos Wave" (another coincidence that Wanda's power is "Chaos Magic"
.....................................................................................................
Cool, so we know it was created in 616,
we know it's pouring into the Omniverse from 616,
so what's going on in 616?
Who's power is over-writing 616?
(from the Official Handbook of the Marvel Universe 2006 Saturnyne bio)
http://img256.imageshack.us/img256/748/w1ka9.th.jpg
"She (Saturnyne) was later present on Otherworld
when Dimension-616 was Engulfed in the Scarlet Witch's Reality Warp ...
Saturnyne showed little hesitation in suggesting destroying 616
to Prevent the Warp SPREADING"
.....................................................................................................
Here is that scene On Panel,
Satynyne talking about the Chaos Wave or as the Official Bio puts it,
the Scarlet Witch's Reality Warp:
http://img142.imageshack.us/img142/223/15473921vq0.th.jpg
"Your Dimension is a Cancer,
bringing Devastation to Branes ALL Along the Sidereal String ...
Sparing Yours condemns the Rest"

Also,
ExodusCloak has done a fine job finding many recent references
to Wanda being responsible (as in it was her power) for cracking the Omniverse.

Or in other words, applying the Chaos Wave (her power) to Re-Create the Omniverse.
