Minimal impact predicted

Based on scientific estimates by the US Geographic Survey (USGS), the risk of high fatalities for this earthquake is classified at level GREEN (low). They expect an 65% likelyhood of between 0 and 1 fatalities, and a 96% chance that the number of fatalities falls no higher than 10.

The USGS classifies the economic impact of this earthquake at level GREEN (low). They expect an 65% likelyhood of between 0 and 1 million US Dollars in economic damage and impact, and a 96% chance that the economic impact of this earthquake falls no higher than 10 million USD.

Roughly 50 million people exposed to shaking

The USGS has published a report estimating the number of people exposed to this earthquake. Acoording to their analysis, roughly 50 million have been exposed to shaking at an MMI level of II or higher.

The highest earthquake impact level for this earthquake is V, which corresponds with moderate shaking and very light damage. Roughly 1,080 people are expected to be exposed to this level. Intensity level III was experienced by the majority of people (around 31 million). In their region, weak shaking and probably no damage can be expected.

People in 4 countries have been exposed to shaking. In India , around 35 million people, with impact levels up to V (moderate shaking, very light damage). In Bangladesh , around 15 million people. Other countries where people were exposed to shaking include Bhutan and China.

People	MMI Level	Shaking	Damage
64,450	I	Not noticable	None
9,044,000	II	Very weak	None
30,790,000	III	Weak	Probably none
10,340,000	IV	Light	Likely none
1,080	V	Moderate	Very light
0	VI	Strong	Light
0	VII	Very Strong	Moderate
0	VIII	Severe	Moderate to heavy
0	IX	Violent	Heavy
0	X	Extreme	Very heavy

Nearby towns and cities

3 countries can be found within 300km of the epicenter of this earthquake: India , Bangladesh and Bhutan .

Morigaon in Assam, India is the nearest significant place from the epicenter. The earthquake occurred 9 kilometer (6 mi) north-northwest of Morigaon. Morigaon experienced an earthquake intensity (MMI Scale) of roughly IV. That level implies light shaking and likely no damage.

Multiple large cities are in proximity of today's earthquake. Guwahati is located 58 km to the west-southwest and experienced an intensity of IV (light shaking, likely no damage). Sylhet is located 165 km to the south-southwest and experienced an intensity of III (weak shaking, probably no damage). Shillong is located 94 km to the south-southwest and experienced an intensity of III (weak shaking, probably no damage).

A complete list of nearby places is included below. Estimated intensity data (MMI) sourced from a shake-map published by the US Geographic Survey is shown where available (cities without data probably experienced little impact).

This is likely an aftershock

This earthquake was an aftershock. A larger mag. 5.2 earthquake struck 10 km (6 mi) east-northeast in advance of this 4.9 earthquake around 13 sec earlier.

Overview of foreshocks and aftershocks

Detected MAG2.5+ earthquakes within within 100km (62 mi), that occurred in the three days before and after the main shock.
Classification	Magnitude	When	Where
Main Shock	M 5.2	Jan 5, 2026 04:17 (Kolkata Time)	-
Aftershock This Earthquake	M 4.9	13 sec later Jan 5, 2026 04:17 (Kolkata Time)	10 km (6 mi) WSW from Main Shock.

More earthquakes coming?

The risk of aftershocks decreases rapidly over time. Usually, aftershocks are at least one order of magnitude lower than a main shock.

The chance that a significant earthquake like this one is followed by an even larger earthquake is not so large. On average, scientists estimate a 94% chance that a major earthquake will not be followed by an even larger one. It is still adviced to be aware of this risk

Earthquakes like this happen often in the region

Earthquakes of this strength are very common in the region. In total, 33 earthquakes with a magnitude of 4.9 or higher have been registered within 300km (186 mi) of this epicenter in the past 10 years. This comes down to an average of once every 4 months.

Tsunami very unlikely

DISCLAIMER: We strongly suggest to closely monitor advice from local authorities with regards to tsunami risks. Our analysis is based on automatically collected data from external sources, and these might contain mistakes. In addition, earthquakes can cause landslides that may lead to a tsunami, or be a followed by another, potentially stonger, earthquake.

While MAG-6.5+ earthquakes may cause tsunami's, it appears that the epicenter of this earthquake hit under land. In addition, the reported depth is deeper than 100km, making the risk of a tsunami even less likely. However always stay cautious and monitor advice from local authorities.

Tsunami Risk Factors

Factor	Under Sea?	MAG-6.5 or stronger?	Shallow depth?
Explanation	Almost all tsunami's are caused by earthquakes with their epicenter under sea or very near the sea. However stay cautious in coastal areas as earthquakes on land may cause landslides into sea, potentially still causing a local tsunami.	Under MAG 6.5: Very unlikely to cause a tsunami. MAG 6.5 to 7.5: Destructive tsunami's do occur, but are uncommon. Likely to observe small sea level changes. MAG 7.6+: Earthquakes with these magnitudes might produce destructive tsunami's.	Most destructive tsunami's are caused by shallow earthquakes with a depth between 0 and 100km under the surface of the earth. Deeper tsunami's are unlikely to displace to ocean floor.
This Earthquake	Not this earthquake. This earthquake appears to have struck on land far from any coast.	Not this earthquake. This earthquake had a magnitude of 4.9. Earthquakes of this strength are unlikely to trigger a tsunami.	This earthquake occurred at a depth of of 35 km (22 mi). Earthquakes this shallow could trigger a tsunami.
