very low rates of seismic activity. In recent years, tremors from
earthquakes in neighbouring states have been felt, most notably in
1969. Minor seismic activity has been recorded (2)
in the vicinity of Chiraikund and Muirpur along the border with Madhya
Pradesh. A few faults which form the eastern section of the
Narmada-Son Fault Zone have shown movement during the Holocene epoch (2).
Another active fault (2) is
the Tatapani Fault which trends in an east-west direction in the
vicinity of Manpura in Sarguja district. In the south, the Godavari
fault, which forms the northern flank of the Godavari Graben run
through the southern part of the state and is also active (2).
The seismic hazard map of India was
updated in 2000 (4) by the Bureau of
Indian Standards (BIS). The main change in the map for the state of Chhatisgarh
was the merging of Zones I and II under which much of the state falls. A sliver
of the district of Dantewara lies in Zone II. Parts of the the northern
districts of Bilaspur, Janjgir, Jashpur, Korba, Koria and Sarguja lie in Zone
III. Since the earthquake database in
India is still incomplete, especially with regards to earthquakes prior to the
historical period (before 1800 A.D.), these zones offer a rough guide of the earthquake hazard in any
particular region and need to be regularly updated

Earthquake in Chhattisgarh
10 October 2000 -
Surta-Ambikapur area, Chhatisgarh,
mb 4.5 (7).
23.060 N, 82.917 E,

This event is located to the north-east of Korba. This event had an ML of 3.7 (3).
The following list briefly outlines known earthquakes in this region
which either had observed intensities of
or higher (historical
events) or had known magnitudes of
M4.5 or more
(instrumented events). General locations are provided for historical events for
which "generalized" epicentral co-ordinates are available.
Some events which were significant for other reasons are also included.
This list will be updated whenever newer information is available. Please note
that Magnitude and Intensity are NOT THE SAME. All events are within the state
or union territory covered on this page unless stated otherwise.
