前言
The magnitude Ms 8.0 (Mw 7.9) Wenchuan earthquake occurred on 12 May 2008 in the LongmenShan region of China——the topographical boundary between the Tibetan Plateau and the SichuanBasin——resulting in extensive damage throughout central and western China. To understand theseismic faulting mechanism and surface deformation features associated with the Wenchuanearthquake, including rupture length, geometric characteristics, and slip distribution of co-seismicsurface rupture, our survey group traveled to the epicentral area 2 days after the earthquake andundertook 10 days of fieldwork, during which time we collected fundamental data related torupture structures and the spatial distribution of offset along faults. Based on the results of thispreliminary fieldwork, we carried out additional detailed fieldwork along the co-seismic surfacerupture over the following year.This photographic atlas shows the main deformation characteristics of co-seismic surfacerupture and the nature of the earthquake disaster and subsequent relief operations, based onphotographs taken during our field investigations. This atlas is intended not only for geologists,seismologists, and engineers as a means of furthering their understanding of the seismicmechanisms and surface rupture deformation characteristics of large intracontinental earthquakes,but also for advanced undergraduates and graduate students as a textbook.We are grateful to the many organizations and individuals who helped to make this bookpossible. Thanks are also due to Professor Dong Jia and Dr. Xiaojun Wu of the NanjingUniversity for their assistance in the field.
内容概要
The Great Wenchuan Earthquake of 2008S: A Photographic Atlas ofSurface Rupture and Related Disaster focuses on the main deformationcharacteristics of co-seismic surface rupture, including rupture length andslip distribution of co-seismic surface rupture caused by the WenchuanEarthquake and its associated relief operation. The magnitude Ms 8.0(Mw 7-9) Wenchuan Earthquake occurred on 12 May 2008 in the LongmenShah region of China, the topographical boundary between the TibetanPlateau and the Sichuan Basin, resulting in extensive damage throughoutcentral and western China. This atlas contains distinct photographs obtainedduring the field investigation carried out immediately 2 days after thequake. The atlas is designed for geologists, seismologists and architectureengineers engaged in seismic mechanisms and surface rupture deformationcharacteristics of large intracontinental earthquakes.

investigations
reveal
that
the
Ms

earthquake
of
12
May
2008
produced
a
285-kin-long
surface
rupture
zone
along
the
Longmen
Shan
Thrust
Belt,
eastern
margin
of
the
TibetanPlateau,
mainly
along
the
pre-existing
Yingxiu-Beichuan,
Guanxian-Anxian,
and
Qingchuanfaults,
which
are
three
of
the
main
active
faults
within
the
thrust
belt.These
faults
define
a
left-stepping

with-10

(generally

Based
on
the
geometry
and
distribution
of
deformation
structures,
the
Wenchuan
rupture
zonecan
be
divided
into
the
northem,
central,
and
southem
segments.
The
northern
segment,
restricted
tothe
fault
trace
of
the
Qingchuan
Fault,
extends
for
-50
km,
terminating
at
the
town
of
Shazhou
in
thenortheast,
near
the
border
between
the
Sichuan
and
Gansu
provinces.
The
central
segment,
-105
km
inlength,
occurs
along
the
northeastern
segment
of
the
Yingxiu-Beichuan
Fault.
The
southem
segment,-130
km
in
length,
branches
into
two
parallel
sub-rupture
zones:
one
along
the
southwestern
segmentof
the
Yingxiu-Beichuan
Fault
between
the
towns
of
Beichuan
and
Yingxiu,
terminating
to
thesouth
of
Yingxiu
town,
and
another
along
the
Guanxian-Anxian
Fault
(which
forms
the
topographicboundary
between
the
Longmen
Shan
Range
and
the
Sichuan
Basin),
terminating
to
the
south
ofDujiangyan
City
near
the
epicentral
area
of
the
Wenchuan
earthquake.Field
investigations
demonstrate
that
(i)
the
Wenchuan
earthquake
occurred
upon
pre-existingactive
faults
of
the
Longmen
Shan
Thrust
Belt;
(ii)
the

into

and
(iii)present-day

of

mostly
