Having lived on Kwajalein for some time and having family there
during typhoon and other storms. I survived the Good Friday
Earthquake and Pacific tidal wave. It reached the island with
a height of 6'.
I fell the Hawaii islands are old. The big one is young. The ones
far to the North west - under water are the oldest and have melted
into the sea. The whole set is sweeping towards the north west and
to the south east of the big island a new island begins.
One of my favorite pictures I took was after a Typhoon hit and
brought us a massive tree. Trees are known to take worms within
as they float. - How about eggs. Or snails.
So transportation upon ocean currents is world wide and North-South
Pacific in specific. e.g. follow the shoes as they float around
after a transport spill.
(Yea - I have a number of those from Kwaj)
