NEW ANIMATIONS!


Megathrust Earthquakes and Alaska!
http://www.iris.edu/hq/programs/education_and_outreach/animations

In recognition of the 50th anniversary of the magnitude 9.2 Great Alaska
Earthquake of March 27th, 1964, IRIS offers a set of three animations
made in collaboration with the U.S. Geological Survey and the Alaska
Earthquake Center. Although the animations share some elements in
common, they each offer a unique story.

*1) The 1964 Great Alaska Earthquake*. Description of the magnitude 9.2
megathrust earthquake, 2nd largest earthquake ever recorded by modern
instruments. The animation explains the magnitude (/Just how big is
9.2/?), rupture processes, elastic rebound, and resulting tsunami. Data
from this earthquake confirmed important aspects of the then-new theory
of plate tectonics.

*2) Tsunamis Generated by Megathrust Earthquakes*. An animation about
tsunami-generating megathrust earthquakes uses examples from Japan,
Chile, and Alaska to describe structures that generate deadly tsunamis
including: megathrust plate-boundary displacement; deformation of the
overriding plate by splay faulting and/or folding; and
earthquake-generated landslides.

*3) Tectonics & Earthquakes of Alaska**---More than just plate
boundaries.* Describes earthquakes of the Aleutian subduction zone
boundary, one of the most seismically active in the world, and the Queen
Charlotte Transform Fault. Explains how Yakutat terrane accretion drives
mountain building and crustal fault earthquakes like the 2002 M7.9
Denali earthquake.
