🜃 Hawaiian Plume & Seamount Glyphs

• Above ~30°N latitude: The plate moves northwest, toward Kamchatka, Aleutians, and Japan
• Below ~30°N: The motion shifts westward with a slight northern tilt, toward Philippines, Taiwan, and Mariana Trench

This creates a fan-like drift, where the plate expands outward, not uniformly, but directionally stretched.

The Hawaiian plume stays anchored, but its surface expression—volcanism—fans out as the plate moves. This leads to:

• Lo‘ihi/Kamaʻehuakanaloa rising southeast of Hawai‘i
• Older islands eroding northwestward
• A widening volcanic corridor, not because the plume expands, but because the plate spreads over it

• The plume itself doesn’t migrate toward California or Asia
• The volcanic chain expands, like ink dragged across parchment
• The bend in the Hawaiian–Emperor chain (~47 Ma) may reflect a change in plate motion, not plume movement

• Younger, active, and aligned with the current Pacific Plate motion
• Includes Lo‘ihi/Kamaʻehuakanaloa, Mauna Loa, Mauna Kea, and the Big Island chain
• Formed as the Pacific Plate drifts northwest over the stationary Hawaiian hotspot

• Older, extinct volcanic remnants
• Stretch northward toward Kamchatka and the Aleutians
• Formed when the Pacific Plate was moving more northerly, before the bend

• Marks a change in plate direction, not plume movement
• Possibly caused by:
  • Collision of India into Asia, altering mantle flow
  • Subduction zone reorganization in the western Pacific
  • Mantle drag or plume tilt

This bend is a glyphic hinge—a ceremonial inflection point in the planetary archive.
