8.1 |
Thirty deaths.
All houses were destroyed in Dzun Bogd
and Bayan Gobi. Subsidence, faulting
and fissures occurred in the Bahar Uula
and Ih Bogd Uul Mountains. The largest
fissure was 250 km (155 mi) long with
as much as 9-11 m (30-36 ft) of
vertical and 3 m (10 ft) of horizontal
offset. Because of the extremely sparse
population in the area, this is perhaps
the least damaging great earthquake to
have occurred on land in the 20th
Century; the direct opposite of the
Agadir, Morocco earthquake of 29 Feb 1960.
