[138], The widespread devastation caused by the tsunami led GAM to declare a cease-fire on 28 December 2004 followed by the Indonesian government, and the two groups resumed long-stalled peace talks, which resulted in a peace agreement signed 15 August 2005. Khao Lak also experienced the largest tsunami run-up height outside of Sumatra. [63] The second wave was the largest; it came from the west-southwest within five minutes of the first wave. The Mw 9.3 Sumatra-Andaman earthquake on December 26, 2004 was the second largest earthquake recorded during the last century. Tsunami run-up measurements along the Sri Lankan coasts are at 2.4–4.11 m (7 ft 10 in–13 ft 6 in). The ground level was about 2 m above sea level, and there were many cottages and hotels. [37] Since movement was vertical as well as lateral, some coastal areas may have been moved to below sea level. [80] In Chuckchucha and Lapati, the tsunami arrived in a three-wave cycle with a maximum tsunami wave height of 12 m (39 ft). Local eyewitnesses described three large waves, with the first wave rising gently to the foundation of the buildings, followed minutes later by a sudden withdrawal of the sea near the port of Ulee Lheue. In the great Aceh–Andaman earthquake of 26 December 2004, most of the estimated 280 000 deaths resulted from the associated tsunami rather than from the earthquake shaking. Most of the loss of life, property and well-being stemming from the great Sumatran earthquake and tsunami of 2004 could have been avoided and losses from similar future events can be largely prevented. [73] Moreover, the largest death toll occurred at Khao Lak, with about 5,000 people killed. Sri Lanka reported that it had received no foreign government aid, while foreign individuals had been generous. Uncountable wells that served communities were invaded by sea, sand, and earth; and aquifers were invaded through porous rock. The second and third waves were 15–30 m (49–98 ft) high at the coast and appeared like gigantic surfing waves but "taller than the coconut trees and was like a mountain". A 'megathrust' earthquake in a subduction zone was the cause of the 2004 Boxing Day tsunami which killed 230,000 people in the Indian Ocean, and the 2011 Tohuku tsunami in … The highest death toll was in Hafun, with 19 dead and 160 people presumed missing out of its 5,000 inhabitants. The maximum runup height of almost 9 m (30 ft) was recorded in Bandarbeyla. [143] In response, the Indian Minister of Home Affairs announced that a fresh onslaught of deadly tsunami was likely along the southern Indian coast and the Andaman and Nicobar Islands, even as there was no sign of turbulence in the region. This ripple effect could especially be felt in the inland provinces of Thailand, such as Krabi, which acted as a starting point for many other tourist destinations in Thailand. Many villages in the state of Andhra Pradesh were destroyed. The waves radiated outwards along the entire 1,600 km (1,000 mi) length of the rupture (acting as a line source). January 21, 2016 January 31, 2016 / cascadiaearthquake / Leave a comment. The United Nations Environment Programme (UNEP) is working with governments of the region in order to determine the severity of the ecological impact and how to address it. Local video recorded that before the arrival of the tsunami, people can be seen swarming the beach to check on stranded fish from the exposed beach. This considerably outweighed the allocation by the government to disaster relief and reconstruction of £75 million and came to an average of about £5.50 (US$10) donated by every citizen. Areas with dense coconut groves or mangroves had much smaller inundation distances, and those with river mouths or backwaters saw larger inundation distances.
