height of . Inundation limit was found to be up to inland. The impact of the waves was so severe that four oil tankers were thrown almost from the seashore near Malacca to the Air force colony main gate. In Chuckchucha and Lapati, the tsunami arrived in a three-wave cycle with a maximum tsunami wave height of . In Campbell Bay of Great Nicobar Island, the tsunami waves hit the area three times with an inundation limit of . A rise in sea level was observed before the first wave came within 5 minutes of the earthquake. The second and third waves came in 10-minute intervals after the first. The second wave was the strongest. The tsunami waves wreaked havoc in the densely populated Jogindar Nagar area, situated south of Campbell Bay. According to local accounts, tsunami waves attacked the area three times. The first wave came five minutes after the mainshock (0629 hrs.) with a marginal drop in sea level. The second wave came 10 minutes after the first one with a maximum height of to 8 m (26 ft) and caused the major destruction. The third wave came within 15 minutes after the second with lower wave height. The maximum inundation limit due to tsunami water was about . The worst affected island in the Andaman & Nicobar chain is Katchall Island, with 303 people confirmed dead and 4,354 missing out of a total population of 5,312. The significant shielding of Port Blair and Campbell Bay by steep mountainous outcrops contributed to the relatively low wave heights at these locations, whereas the open terrain along the eastern coast at Malacca and Hut Bay contributed to the great height of the tsunami waves. Reports of tsunami wave height: at Diglipur and Rangat at North Andaman Island high at Campbell Bay on Great Nicobar Island high at Malacca (in Car Nicobar Island) and at Hut Bay on Little Andaman Island high at Port Blair on South Andaman Island Maldives The tsunami severely affected the Maldives at a distance of from the epicentre. Similar to Sri Lanka, survivors reported three waves with the second wave being the most powerful. Being rich in coral reefs, the Maldives provides an opportunity for scientists to assess the impact of a tsunami on coral atolls. The significantly lower tsunami impact on the Maldives compared to Sri Lanka is mostly due to the topography and bathymetry
