October 21, 1907 Earthquake: Karatag, Tajikistan

Oct 21, 1907, 04:23:20 UTC, 38.5 N, 67.9 E, depth 35 km, magnitude 7.4 MS, intensity IX.

Oct 21, 1907, 04:44 UTC, 38.7 N, 68.1 E, depth 24 km, magnitude 7.3 MS.

According to the reports "...A grandiose misfortune encompassed. .. the whole region on the southern slope of the Gissar Range .... The misfortune resulted from a series of average earthquakes. In terms of the size of the affected area, the extent of damage, and in the number of victims. The region of greatest destruction primarily encompassed the southern slope of the Gissar Range.

... The earthquake hit the mountains, destroying

all the mountain kishlaks (villages in Central

Asia). . . . Besides Karatag, almost destroyed by the

earthquake, several other kishlaks in the Gissar and

Denau regions also were heavily damaged--some to an

even greater extent. The earthquake inflicted human

losses and killed domestic stock. Topographic

changes...occurred in many places in the macroseismic

zone. They were limited mainly to landslides of steep

forested river banks, ravines, and steep slopes of high

hills . . . Slides of rooted rock were also noted in

several places."

Two tremors are clearly isolated on the seismograms of the European stations, providing a separate definition of the M (an independent determination of the MLH was made by Professor M. Bath for the two tremors). Macroseismic information for the two tremors is

difficult to separate. According to N. V. Shebalin,

the first tremor may be linked with the meridian fracture, and the second with the latitudinal fracture.
