What’s TSUNAMI?

Tsunami is a series of waves of long wavelength

. . .usually generated by a violent, impulsive undersea disturbance

. . or activity near the coast

. . or in the ocean.

What’s TSUNAMI?•When a sudden displacement of a large volume of water occurs,

•or if the sea floor is suddenly raised or dropped by an earthquake •or non seismic disturbances such as volcanic eruptions

•or underwater landslides occurs

- big tsunami waves can be formed by forces of gravity.

What’s TSUNAMI?It should be noted that not all

earthquakes generate tsunamis. Usually, it takes an earthquake with a Richter magnitude exceeding 7.5 to produce a destructive tsunami.

Difference between Tides & Tsunamis

Normal Tides are caused by the extraterrestrial, gravitational influences of the moon, sun, and the planets.

Which are likely zones for Tsunami?

By far, the most destructive tsunamis are generated from large, shallow earthquakes - -with an epicenter or fault line near or on the ocean floor.

These usually occur in regions of the earth characterized by tectonic subduction along tectonic plate boundaries.

History of TsunamisOne of the largest and most destructive tsunamis ever

recorded prior to the latest was generated in August 26, 1883 after the explosion and collapse of the volcano of Krakatoa (Krakatau), in Indonesia. This explosion generated waves that reached 135 feet, destroyed coastal towns and villages along the SundaStrait in both the islands of Java and Sumatra, killing 36, 417 people.

History of TsunamisIt is also believed that the destruction of the Minoan civilization in Greece was caused in 1490 B.C. by the explosion/collapse of the volcano of Santorin in the Aegean Sea.

Tsunamis-Where & How often?Most tsunamis occur in the Pacific

Ocean and its marginal seas. The reason is that the Pacific covers more than one-third of the earth's surface and is surrounded by a series of mountain chains, deep-ocean trenches - where most earthquakes occur.

Tsunamis-Where & How often?

On the average about half-a-dozen times per century, a tsunami from one of the Pacific regions sweeps across the entire Ocean.

Tsunamis-Where & How often?In the last decade alone, destructivetsunamis have occurred 13 times…Nicaragua (1992), Indonesia (1992, 1994, 1996, 2004),Japan (1993), Philippines (1994), Mexico (1995), Peru (1996,2001),Papua-New Guinea (1998), Turkey (1999), and Vanuatu (1999).

SRI Guest House – a Venue for

Shelter and

Crisis Management Operations

• Some of our colleagues lost their life. • Some lost their near and dear. • Most of the unfortunate victims were women

and children.• Some lost their entire life’s earnings.• Let all the traumatised overcome the grief,

sorrow and shock at the earliest. • Anupuram township provided much needed

shelter to many residents of Kalpakkam Township.

• SRI Guest House provided shelter to thousands of Kalpakkam residents including many from nearby villages.

• Imagine the plight of many if we did not have the Anupuram Township and SRI Guest House
