Intermediate to deep focus earthquakes with a focal depth of 60 km or greater are immediately ruled out as the source because no known historical events of the same kind have generated a large tsunami. The 1938 Banda Sea earthquake, an intermediate depth magnitude 8.5 event only caused a minor tsunami. [1]
In the Class 7 textbook topic titled “Our Pasts-2”, pages 48 and 49 have been excluded. These pages mentioned “Mughal Emperors: Major campaigns and events.” The deletions also affected Biology and Chemistry textbooks as the theory of evolution and the periodic table were also purged from class 10 NCERT textbooks.

Amplitude, Wave Height, or Tsunami Height: Refers to the height of a tsunami relative to the normal sea level at the time of the tsunami, which may be tidal High Water, or Low Water. It is different from the crest-to-trough height which is commonly used to measure other type of wave height.
Tsunami On Shikoku, the greatest inundation heights were 7.5 m in Mugi , 7.5 m in Kamikawaguchi ( Japanese : 上川口) of Kuroshio , [ 10 ] 7.2 m at Asakawa on the Tokushima coast, 7.4 m at Usa , 8.4 m at Ōnogō in the Susaki area, 8.3 m at Kure on the Kōchi coast and 5 m at both Hisayoshiura and Kaizuka on the coast of Ehime .

A megathrust earthquake caused a 15 m (49 ft) tsunami, which was recorded to have affected the Banda Islands about 30 minutes after the quake. The effects of the tsunami were reported as far as 230 kilometres (140 mi) away in Ambon. [2] Many trees in the Banda Islands were reported to have been uprooted. [3]
The tsunami triggered by the mainshock was large and corresponded with a tsunami magnitude (M t ) of 8.7. Estimates of the moment magnitude range from 8.3 to 8.6. [ 11 ] The length of the plate boundary that ruptured during the earthquake is estimated to be 300 to 450 km (190 to 280 mi).
