Earthquake History
Chhatisgarh has 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).

Seismic Hazard

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 (See also: GSHAP Hazard Map for Chhattisgarh).

Largest Instrumented Earthquake in Chhattisgarh
10 October 2000 - Surta-Ambikapur area, Chhatisgarh, mb 4.5 (7).

23.060 N, 82.917 E, D=005.4 kms, 06:11:32 UTC (

Significant Earthquakes  in Chhattisgarh
The following list briefly outlines known earthquakes in this region which either had observed intensities of
V 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.

Acronyms Used:
D=Depth, OT=Origin Time, Mw=Moment Magnitude, Ms=Surface Wave magnitude, Mb=Body Wave Magnitude, ML=Local Magnitude, M?=Magnitude Type unknown

This listing will be modified without notice. Please check back for the latest version when using it elsewhere. Additionally, please reproduce using appropriate CITATIONS/CREDITS.
