Status of Mangroves in the Coastal Environment Changes: A Case Study after the Nias Earthquake, March 2005 | Chapter 07 | Emerging Challenges in Environment and Earth Science Vol. 2

 Sixteen years ago, on December 26, 2004, a 9.3 magnitude earthquake struck the Andaman Islands, followed by tsunamis in the Aceh region, resulting in massive losses of human life in Indonesia's coastal areas and neighbouring countries. Hundreds of hectares of coral reef ecosystem were hoisted into the ground after an 8.7 Mw earthquake struck Nias on March 28, 2005. Drought killed many corals, and quake vibrations caused many to fall. Similarly, raised land caused most mangroves to relocate away from the shoreline.

The goal of the study is to track the evolution of coastal ecosystems, particularly mangrove adaptability to physical and ecological changes. Landsat imageries were analysed using remote sensing techniques and coastal profile measurements were employed in the study. On Augustus 2005, December 2014, and December 2015, a series of field researches were conducted.

Mangroves had relocated away from the shoreline, and while most died due to drought, others survived and developed towards the new coastline, according to the findings.
