A significant earthquake caused severe shaking in Dushanbe, Tajikistan, where residents reported MMI VIII intensity, while moderate tremors hit Kabul and Swat. User reports indicate the seismic event was felt across a wide geographic area, including parts of Uzbekistan, Pakistan, and India, causing objects to rattle and buildings to sway.
Where was the shaking most intense?
According to user-submitted reports, the most severe impact occurred in Dushanbe, Tajikistan. Residents living on the 12th floor described the event as “severe shaking” involving both vibration and rolling that lasted between one and two minutes. This corresponds to a Modified Mercalli Intensity (MMI) of VIII.
Other high-intensity zones included:
- Dharamshala, India: Reported MMI VI (Strong shaking), with residents noting that beds shook “terribly.”
- Kabul, Afghanistan and Swat Haronabad, Pakistan: Reported MMI V (Moderate shaking). Residents in Kabul described the sensation as “very high.”
- Mardan, Pakistan: Reported MMI IV (Light shaking), where the shaking lasted between 30 and 60 seconds accompanied by a continuous low rumbling sound.
In contrast, regions like Sialkot, Pakistan, experienced only MMI II (Very weak shaking), where movement was felt primarily as a slight back-and-forth motion while lying down.
How did the earthquake manifest in different regions?
The physical sensations of the quake varied significantly based on location and building type. In Mazari Sharif, users reported “strong beats” and a constant horizontal swinging that made the floor feel unstable. This sideways movement was a common theme across Central Asia.
In Tashkent, Uzbekistan, the tremors caused physical disruptions in homes. One resident reported that glass closet doors rattled loudly during two minutes of shaking. In Samarkand, the sensation was so pronounced that one user reported feeling dizzy and seeing “rings” form in their tea cup due to the vibration.
In Shymkent, Kazakhstan, the movement was felt even in outdoor settings. Reports included light waves moving through swimming pools and shampoo bottles falling in bathrooms. These varied accounts illustrate how seismic waves interact differently with various environments and objects.
Altitude and Perceived Intensity
Data suggests a correlation between building height and the perceived severity of the tremor. While ground-level residents in some areas reported simple vibrations, those in higher elevations—such as the 12th-floor resident in Dushanbe or the 6th-floor resident in Islamabad—noted more significant swaying and prolonged duration of the movement.
How is crowdsourced reporting shaping seismic awareness?
The rapid collection of real-time data from residents is becoming a critical trend in seismic monitoring. Traditional seismographs measure ground motion, but they cannot capture the human experience, such as the “dizziness” reported in Samarkand or the specific “rumbling” heard in Mardan.
As mobile connectivity improves across Central and South Asia, the integration of citizen-science reports into official disaster response models is likely to increase. This trend allows geologists to map “felt intensity” more accurately, providing a more nuanced view of how earthquake waves travel through specific geological formations in regions like the Hindu Kush.
Frequently Asked Questions
What is the MMI scale?
The Modified Mercalli Intensity (MMI) scale uses Roman numerals (I through XII) to describe the effects of an earthquake on people, buildings, and the natural environment.
Why did some people feel shaking while others did not?
Intensity depends on the earthquake’s magnitude, the depth of the epicenter, the distance from the epicenter, and local soil conditions.
How long do these tremors typically last?
Based on recent reports, shaking durations varied from 2 seconds in Shymkent to approximately 2 minutes in Dushanbe and Tashkent.
