Two automated tsunami sirens in South Andaman will undergo a scheduled sound test on August 13, part of an ongoing effort to maintain the islands’ readiness against potential coastal hazards. The sirens, located at the premises of the District Office in South Andaman and the Tehsil Office in Ferrargunj, will be sounded between 10 am and 3 pm.
Authorities have informed residents that the activation is purely for testing purposes. They have urged the public not to panic when the sirens sound and to remain calm during the process. The check is aimed at verifying the operational status, sound range, and clarity of the alerts, ensuring that the system can deliver a clear and audible warning in the event of a real emergency.
The Andaman & Nicobar Islands, given their location along the seismically active “Ring of Fire” in the Indian Ocean, are considered one of India’s most sensitive zones for earthquake and tsunami risk. The memory of the 2004 Indian Ocean tsunami, which claimed thousands of lives across multiple countries, remains a key reason for sustained investment in early warning systems here.
The automated sirens are part of a broader disaster management network that includes seismic monitoring, ocean buoys, and communication protocols designed to relay alerts from the Indian National Centre for Ocean Information Services (INCOIS) in Hyderabad to local administrations. Once a tsunami warning is issued, the sirens serve as the last-mile alert mechanism, especially critical for communities without instant digital access.
Testing these systems is more than a technical formality. Sound checks help identify mechanical issues such as battery failure, speaker damage, or wiring faults that could compromise performance in an actual emergency. They also give residents an opportunity to familiarise themselves with the sound pattern of the warning siren, an essential factor in ensuring quick and correct public response when every second counts.
Earlier coverage by The Wave Andaman on tsunami preparedness highlighted how timely warnings can significantly reduce casualties and damage, particularly when backed by clear evacuation routes and community drills (Read the full preparedness report here). This latest test fits into that same safety framework, reinforcing the operational readiness of frontline alert systems.
Officials say the testing window between 10 am and 3 pm has been chosen to maximise the likelihood of staff availability and public awareness while minimising disruption to daily routines. By informing residents in advance, the administration aims to avoid unnecessary alarm and prevent emergency lines from being overwhelmed by calls reporting the siren as a live warning.
In many coastal regions worldwide, such as Japan and parts of the Pacific Northwest, monthly or quarterly siren tests are standard practice. In the Andaman & Nicobar Islands, where the terrain and scattered settlement patterns can make rapid mass communication challenging, sirens remain a critical physical-layer alerting tool.
The test also serves as a reminder for households and institutions to review their own emergency response plans. Knowing the nearest safe zones, keeping basic emergency kits, and having pre-agreed family communication points can make a substantial difference in the aftermath of a tsunami or earthquake..
As August 13 approaches, residents in the vicinity of the District Office, South Andaman, and the Tehsil Office, Ferrargunj, are advised to treat the siren activation as a familiarisation exercise. Recognising the sound and understanding its purpose are key components of community resilience in a hazard-prone region.
