Planet Earth’s
  Convergent Plate
  Motion Causes:


Tsunamis
 (e.g., 3-4 m
 waves in
 Japan)
LOCATION: 133 KM (80 MI) OFF
  EAST COAST OF HONSHU
   OFFSHORE EPICENTER
• It only took seconds for the P-
  and S-waves and minutes for
  the tsunami waves to reach
  Sendai..
   PRELIMINARY SOCIETAL
         IMPACTS
• Ground shaking lasted 300 seconds
  (compared with about 10 - 20 seconds
  for the 1994 Northridge, CA or the 1995
  Kobe, Japan quakes).
• Hundreds of aftershocks, many in the
  M6+ range and comparable in size with
  the damaging 1971 San Fernando CA
  quake, followed the main shock.
   PRELIMINARY SOCIETAL
         IMPACTS
• The tsunami following within about 10
  minutes, changing coast lines and
  inundating land that will never be used
  again.
• The earthquake ground shaking and the
  tsunami wave run up together caused
  major damage in northern Japan.
• Simultaneously, wide spread fires
  burning out of control seared the land.
   PRELIMINARY SOCIETAL
         IMPACTS
• Some of the nuclear power plants in the
  region shut down automatically, leading
  to an evacuation of several thousand.
• Radiation levels 1,000 times normal
  levels at some locations.
• Four million left without electricity.
• Metro and trains shut down.
PASSENGERS STRANDED:
   SENDAI STATION
   PRELIMINARY SOCIETAL
         IMPACTS
• Vertical evacuation to escape the
  tsunami wave run up was a priority.
• Search and rescue: an urgent need over
  a wide geographucal area.
• Mass care and health care needs
  escalated.
• With so many people missing, deaths
  are expected to reach in the thousands.

  of Japan, sweeping away boats, cars,
  homes and people, then raced across
  the Pacific at 800 mph before hitting
  Hawaii and the West Coast of the USA..
