Acehnese peopleThe Acehnese (also written as Atjehnese and Achinese) are an indigenous ethnic group from Aceh, Indonesia on the northernmost tip of the island of Sumatra. The area has a history of political struggle against the Dutch colonial rule. The vast majority of the Acehnese people are Muslims. The Acehnese people are also referred to by other names such as Lam Muri, Lambri, Akhir, Achin, Asji, A-tse and Atse. Their language, Acehnese, belongs to the Aceh–Chamic group of Malayo-Polynesian of the Austronesian language family.
Rayleigh waveRayleigh waves are a type of surface acoustic wave that travel along the surface of solids. They can be produced in materials in many ways, such as by a localized impact or by piezo-electric transduction, and are frequently used in non-destructive testing for detecting defects. Rayleigh waves are part of the seismic waves that are produced on the Earth by earthquakes. When guided in layers they are referred to as Lamb waves, Rayleigh–Lamb waves, or generalized Rayleigh waves.
Earthquake predictionEarthquake prediction is a branch of the science of seismology concerned with the specification of the time, location, and magnitude of future earthquakes within stated limits, and particularly "the determination of parameters for the next strong earthquake to occur in a region". Earthquake prediction is sometimes distinguished from earthquake forecasting, which can be defined as the probabilistic assessment of general earthquake hazard, including the frequency and magnitude of damaging earthquakes in a given area over years or decades.
Nicobar districtNicobar district is one of three districts in the Indian union territory of Andaman and Nicobar Islands. The district's administrative territory encompasses all of the Nicobar Islands, which are located in the Indian Ocean, between the Bay of Bengal and the Andaman Sea. The headquarters of the district is the village of Malacca, located on the island of Car Nicobar. The district administration is headed by a Deputy Commissioner, who in turn reports into the Lt. Governor of the Andaman and Nicobar Islands.
GalleGalle (ගාල්ල; காலி) (formerly Point de Galle) is a major city in Sri Lanka, situated on the southwestern tip, from Colombo. Galle is the provincial capital and largest city of Southern Province, Sri Lanka and is the capital of Galle District. Galle was known as Gimhathiththa before the arrival of the Portuguese in the 16th century, when it was the main port on the island. Ibn Batuta, a Moroccan Berber Muslim traveller in the 14th century, referred to it as Qali.
Phuket provincePhuket (ˌpuːˈkɛt; ภูเก็ต, phūː.kèt, Bukit or Tongkah) is one of the southern provinces (changwat) of Thailand. It consists of the island of Phuket, the country's largest island, and another 32 smaller islands off its coast. It lies off the west coast of mainland Thailand in the Andaman Sea. Phuket Island is connected by the Sarasin Bridge to Phang Nga province to the north. The next nearest province is Krabi, to the east across Phang Nga Bay. Phuket province has an area of , somewhat less than that of Singapore, and is the second-smallest province of Thailand.
CuddaloreCuddalore, also spelt as Kadalur (kʌdəˈlɔər), is the city and headquarters of the Cuddalore District in the Indian state of Tamil Nadu. Situated south of Chennai, Cuddalore was an important city and port during the British Raj. While the early history of Cuddalore remains unclear, the city first rose to prominence during Pallavas and Medieval Cholas' reign. After the fall of Cholas, the town was ruled by various dynasties like Pandyas, Vijayanagar Empire, Madurai Nayaks, Thanjavur Nayaks, Thanjavur Marathas, Tipu Sultan, French and the British Empire.
Volcanic arcA volcanic arc (also known as a magmatic arc) is a belt of volcanoes formed above a subducting oceanic tectonic plate, with the belt arranged in an arc shape as seen from above. Volcanic arcs typically parallel an oceanic trench, with the arc located further from the subducting plate than the trench. The oceanic plate is saturated with water, mostly in the form of hydrous minerals such as micas, amphiboles, and serpentines. As the oceanic plate is subducted, it is subjected to increasing pressure and temperature with increasing depth.
AcehAceh (ˈɑːtʃeɪ , aˈtʃɛ(h); Acèh atʃeh), officially the Province of Aceh (Provinsi Aceh), is the westernmost province of Indonesia. It is located on the northern end of Sumatra island, with Banda Aceh being its capital and largest city. It is bordered by the Indian Ocean to the west, Strait of Malacca to the northeast, as well bordering the province of North Sumatra to the east, and shares maritime borders with Malaysia and Thailand to the east, Maldives, British Indian Ocean Territory, Sri Lanka to the west, Andaman and Nicobar Islands of India and Myanmar to the north.
Megathrust earthquakeMegathrust earthquakes occur at convergent plate boundaries, where one tectonic plate is forced underneath another. The earthquakes are caused by slip along the thrust fault that forms the contact between the two plates. These interplate earthquakes are the planet's most powerful, with moment magnitudes (Mw) that can exceed 9.0. Since 1900, all earthquakes of magnitude 9.0 or greater have been megathrust earthquakes.
