- NDMA’s seismo.gov.in website crashed during the tremors, hindering access to crucial information.
- Google’s Android Earthquake Early Warning system sent alerts in regions near the India-Nepal border where shaking was stronger, the tremors in Delhi did not trigger alerts due to their lower intensity
