Preface of Special Issue on “Reconnaissance Report on the ,**-
Bam Earthquake in Southeastern Iran”
This is a reconnaissance report on the Bam earthquake (Mw0./), which occurred in
southeastern Iran on December ,0, ,**-. This earthquake caused catastrophic damage to
Bam city and neighboring villages with a collective population of about +.,,***. ,0,,1+
persons were killed [Statistics Center of Iran] and tens of thousands of people were injured.
This means that about +3 of the population in and around Bam city were killed. The
well-known historic citadel Arg-e-Bam, which was the biggest adobe (mud brick) complex
in the world and recently added to the list of World heritage sites by UNESCO, was also
severely damaged by the Bam earthquake (Fig. + next page). The main reason for such
massive damage is the weakness of adobe and brick houses. However, the damage was
disproportionately and unexpectedly large in comparison with the magnitude of the
earthquake. The Bam fault (Fig. , next page), which was well known before the earth-
quake, extends along the west side of Baravat village, about /km southeast of Bam city.
Just after the earthquake it was supposed that the mainshock had occurred in the
geological Bam fault. However, clear evidence of big dislocation on this fault could not be
found (Okumura et al. in this volume). The earthquake has drawn strong interest among
researchers and those who are concerned about earthquake disaster mitigation in Japan,
because earthquakes with such a magnitude have occurred in the past and will occur in
the near future under urban areas in Japan.
To investigate seismological and geological issues, earthquake damage to buildings
and lifelines, and rescue and relief, Japanese reconnaissance teams were dispatched to
Bam city mainly with grand-in aid for scientiﬁc research No. +/2***+- from Monbu-
Kagaku-Sho (The Ministry of Education, Culture, Sports, Science and Technology of
Japan). This special issue presents the papers of those investigations. We thank the
Earthquake Research Institute (Dr. Makoto Ueshima in charge of Scientiﬁc Report Com-
mittee), the University of Tokyo for allowing presentation of these papers in this special
issue of the Bulletin of the Earthquake Research Institute.
