East Coast Current Affairs - 2020

Indian National Centre for Ocean Information launched new Alert System

The Hyderabad based INCOIS (Indian National Centre for Ocean Information) launched a new alert system that will help reduce damage and losses to fishermen due to swell surges. The Swell Surges splash strong waves in the coast damaging boats and nets. The system will help fishermen to get prior alerts about swell surges and safeguard their boats.

Highlights

The INCOIS, an autonomous body operating under Ministry of Earth Sciences launched the alert system that will help provide early warnings about Swell Surges. This is to be launched exclusively for coastal population. The Coastlines of Indian Sub-continent after Tsunami has been experiences damages due to swell waves that originate in distant Southern Indian Ocean.

The Swell Surges are more common in west coast than the east coast.

What are Swell Surges?

A Swell Surge is caused due to surface gravity. They are surface gravity waves and not wind waves (the common waves). Wind Waves are generated by the local winds. On the other hand, swell surges are generated due to distant weather systems.

They take place without any noticeable changes in local winds or coastal environment.

Home Ministry conducts Multi State Mega Mock Tsunami Exercise 2017

The Ministry of Home Affairs (MHA) conducted Multi State Mega Mock Tsunami Exercise 2017 along the entire East Coast in 31 coastal districts across four States.

It was conducted through National Disaster Management Authority (NDMA) and Indian National Centre for Ocean Information Services (INCOIS). The exercise was one of various activities conducted as part of observation of 2nd World Tsunami Awareness Day (observed on November 5).

Key Facts

The exercise was simultaneously conducted in 31 coastal districts across four States – West Bengal, Odisha, Andhra Pradesh and Tamil Nadu and Puducherry (UT) along entire East Coast. It aimed to assess and help improve preparedness, response mechanism and coordination among concerned agencies.

It was for first time entire eastern coast will participate simultaneously in mock exercise. During it, disaster scenario simulating tsunami waves originating due to high-intensity earthquake near Andaman and Nicobar Islands causing massive tsunami along east coast of India was created.

Officials from all important departments such as Indian Army, Navy, Air Force, National Disaster Response Force (NDRF), police, health, education, firefighting, Civil Defense, electricity, transport, public relations, etc. participated in the exercise. The exercise helped participants to get familiarise with their responsibilities, actions required and also helped them to evaluate their Standard Operating Procedures (SOPs) for tsunami warnings.

Participants from 11 Pacific Island countries also observed exercise to take away key lessons and best practices for responding to disaster situation due to Tsunami.

Background

Tsunami is a highly devastating natural hazard, and requires rapid response. India’s eastern coast is susceptible to both floods and tsunamis. The eastern coast of India had faced the devastating tsunami in December 2004 that claimed around 230000 lives. The devastating tsunami in Indian Ocean was formed due to high-intensity earthquake with its epicenter off the west coast of Sumatra, Indonesia.  It had affected lives and the natural environment in six countries in the region including India, Maldives, Sri Lanka, Somalia and Thailand.
