Description:
"Myanmar is one of the earthquake prone countries since it is located in the Alpide
Earthquake Belt. Myanmar has already experienced many destructive earthquakes and for
examples are 1839 Innwa earthquake, 1930 Bago earthquake, 1956 Sagaing earthquake,
1912 Maymyo earthquake. All of these events are of the magnitude ≥ 7.0 (Mw). These
earthquakes caused several hundreds casualties and damages of various kinds of buildings.
The 1839 Innwa earthquake caused about 400 deaths as the total in and around Amarapura;
and many buildings destroyed. The deadiliest earthquake happened in Myanmar is the 1930
Bago earthquake strucked on May 30 and the magnitude is 7.3 Mw. It caused 500 deaths in
Bago and 50 in Yangon; and many buildings damaged. The 1930 Bago earthquakes seems
to be one of the four major earthquakes sequence; August 8, 1929 (Swa) earthquake, May
5, 1930 (Bago) earthquake, December 3, 1930 (Phyu) earthquake in the southern segment
of Sagaing Fault and January 27, 1931 (Putao) earthquake in the northern segment of that
fault. All of these events were originated from the right-lateral strike-slip Sagaing Fault. It can
be therefore regarded that the cities located along this fault are very high in the future
occurrences of the large events. The major cities lied along that fault are Sagaing,
Mandalay, Meiktila, Naypyitaw, Taungoo and Bago.
As the first step, with the aid of the United Nations Human Settlements Programme
(UN-HABITAT), Myanmar Geosciences Society (MGS), Myanmar Engineering Society
(MES) and Myanmar Earthquake Committee (MEC) conducted the seismic risk assessment
for three cities; Sagaing City (Sagaing Region); and Taungoo and Bago Cities (Bago Region).
The project will include two portions as the seismic hazard assessment (SHA) and seismic
risk assessment (SRA). MGS and MEC conducted SHA, while MES performed SRA. This
report will represent the results of SHA for one of these three cities, Bago City, Bago Region.
The main objective of the present project is to develop the seismic hazard and risk
maps of the city. To develop the seismic hazard maps, the methodology of probabilistic
seismic hazard assessment (PSHA) is applied and the resulted seismic hazards are
presented in terms of peak ground acceleration (PGA), spectral acceleration (SA) and peak
ground velocity (PGV) for 10% and 2% probability of exceedance in 50 years (475 years and
2,475 years recurrence intervals). The resulted seismic hazards are lead to use in the SRA
and additionally these hazard maps are very useful for the urban land-use planning and the
seismic resistance building construction purposes..."
