Traditional Structures

The damage sustained by buildings and structures in the Andaman and Nicobar islands area was due to earthquake shaking and/or giant tsunami waves. While damage on Little Andaman Island and all the Nicobar Islands was predominantly tsunami-related, damage on islands north of Little Andaman Island was primarily due to earthquake shaking even though tsunami waves and high tides were also a concern. In general, the building stock consists of a large number of traditional and non-engineered structures. Many traditional structures are made of wood, and they performed well under the intensity-VII earthquake shaking sustained along the islands. However, a number of new reinforced concrete (RC) structures suffered severe damage or even collapse. Also, extensive damage occurred to the coastal and harbor structures in the Andaman and Nicobar islands.

Lifeline Systems

Lifeline systems in the Andaman and Nicobar islands performed poorly during the December 2004 Great Sumatra earthquake and tsunami. Several power stations and transmission lines were damaged by the ground shaking, affecting the electric power supply to parts of the islands. Telecommunication services were severely affected because of destruction of several telephone exchanges. These services were restored quickly by government agencies. The dams and reservoirs, which supply potable water, sustained minor damage from ground shaking. However, segmented pipelines connecting the dams and reservoirs to various storage sites broke at several places, which significantly affected the water supply for a few days. Ground shaking damaged several elevated as well as ground-supported storage tanks. Damage related to tsunami waves was substantial in the 500–1,000- m strip immediately next to the coastline.

Takahashi (1942) described Dialeurotrachelus cambodiensis, the type species of the monotypic whitefly genus, Dialeurotrachelus Takahashi from three syntype specimens collected on an unidentified tree in Cambodia, which were subsequently lost or destroyed. It was rediscovered after eight decades in the Indian territories of the Andaman and Nicobar Islands. A neotype is designated for D. cambodiensis Takahashi, from specimens collected on Diospyros kurzii Hiern (Ebenaceae) from Andaman Island, India. It is recorded for the first time from the Indian territories, Andaman and Nicobar Islands. Pupal morphology is assessed for redefining the generic description with differential diagnoses from related genera, and anomalies involved with structure of the vasiform orifice and associated structures are discussed. Illustrations are provided of the puparia in life, camera lucida drawings, slide mounts, and scanning electron photomicrographs.

Boats and ships are the major modes of transportation among the Andaman and Nicobar group of islands. The Andaman Trunk Road also forms an important part of the transportation system in the Andaman Islands north of Port Blair. The harbor structures in the islands were the most affected during the ground shaking; the result heavily disrupted the lives of the island residents. These transportation systems are expected to be in working condition after a major disaster, to facilitate the search and rescue operations and the relief work in the affected areas. A reconnaissance team surveyed the damage that the 2004 earthquake and tsunami caused to the transportation structures in the islands. Damage was observed in all transportation systems, including harbors, highways, airports, and hangars.

Reconnaissance Surveys

Plate tectonics after the 26 December 2004 Great Sumatra earthquake resulted in major topological changes in the Andaman and Nicobar islands. Aerial and land reconnaissance surveys of those islands after the earthquake provide evidence of spectacular plate tectonics that took place during the earthquake. Initial submergence of the built environment and the subsequent inundation upon arrival of the tsunami wave, as well as emergence of the new beaches along the islands—particularly on the western rims of the islands and in the northern islands—are the major signatures of this Mw=9.3 event.

A New Species

The systematic position of the agamid genus Coryphophylax (Squamata: Agamidae) is given as monotypic and endemicto the Andaman and Nicobar Islands in the Bay of Bengal, India. After having surveyed intensively in thirteen differentIslands and examined several individuals in the Andamans group of islands, we describe a second species ofCoryphophylax from the lowland rainforests of the South Andaman Island. Coryphophylax brevicaudus sp. nov. isdifferentiated from its congener, C. subcristatus (Blyth, “1860” 1861) by its smaller size, relatively shorter tail, presenceof nuchal and dorsal crests in both sexes, midbody scale row counts and colour pattern. The new species lives in sympatrywith C. subcristatus. The taxonomic history and systematic status of the genus Coryphophylax are discussed, and the need for continued surveys in the Islands is emphasized.

Rescue And Relief

The rescue and relief work undertaken in the Andaman and Nicobar islands and in mainland India after the 26 December 2004 Indian Ocean tsunami was massive. A number of new initiatives undertaken by the government and nongovernmental agencies were innovative and successful. Also, since the tsunami was not a typical disaster for India, it raised a number of new concerns related to reconstruction along the coast.
