Describe
what
occurs
in
the
lead-up
to
a
megathrust
earthquake.
The
tectonic
plate
moves
toward
one
another
continually
but
can
get
stuck
in
contact.

How
does
a
core
sample
from
the
ocean
floor
reveal
a
past
earthquake
event?
The
sample
contains
bands
of
rocks
and
chunks
of
wood
debris
which
are
the
results
of an
earthquake,
revealing
what
happened
during
the
earthquake.

Why
was
the
Christchurch
earthquake
of
2011
a
surprise
to
scientists?
Scientists
didn’t
even
know
there
was
a
fault
in
the
region.
4.
What
is
the
proposed
reason
for
the
seismic
activity
on
Baffin
Island
in
Nunavut?
Seismic
activity
may
be
caused
by
the
group
slowly
rising
thousands
of
years
after
the
glaciers
that
once
covered
it
melted

What
is
currently
occurring
on
Vancouver
Island
that
provides
a
clue
to
a
potential
future
earthquake
there?
Surface
of
the
island
is
rising
2
mm
per
year
on
its
western
edge.

to

amount
of

What
are
the
beneficial
applications
of
the
motion
sensors
that
Oceans
Network
Canada
is
currently
prototyping
on
Vancouver
Island?

How
have
the
Indigenous
Peoples
on
the
west
coast
of
the
island
been
preparing
for
a
potential
tsunami?
They
are
building
subdivisions
on
the
hill
which
are
high
grounds,

the
kids,
who

15
minutes
to

Based
on
the
window
forecasted
by
the
scientists
at
the
Sidney
laboratory,
in
what
time
range
will
the
next
strong
earthquake
occur
in
the
region?
(Provide
the
range
by
giving
the
specific
years).
