The 1941 Andaman Islands earthquake struck the
Andaman and Nicobar Islands, India and British Ceylon (now known as Sri Lanka). There may have been damage and deaths in Bangladesh, Myanmar, and Thailand
due to the tsunami.
Effects
The earthquake partially collapsed
sand volcanoes were reported. Roads, bridges, embankments, seawalls and jetties were seriously damaged. Large fissures occurred in the ground. Large trees were tilted and uprooted. According to eyewitness accounts, these trees fell in a westernly direction. There was an unspecified number of deaths only described as "few". Shaking was felt over a very wide area; felt reports also came from Colombo, Chennai, Kolkata and Mumbai.[3] Islands located in a passage between Little Andaman and South Andaman Islands subsided by over 1.5 m (4 ft 11 in).[2]
Tsunami
Although no
Times of India did not mention a tsunami while reporting the event. No news or scientific reports made mention of a large death toll from the tsunami. It was also unlikely that a 1 m (3 ft 3 in) tsunami could result in a high death toll. Reports of the tsunami effects along the Andaman Islands also did not mention any fatalities.[4]
Geology
The earthquake occurred in a
normal-faulting intraslab earthquake located within the Indian Plate beneath the islands.[5]
