Keywords:tsunami caused by a volcanic eraption, accurate measurement of height of a tsunami, the tsunami generated by the 1741 Oshima-Ooshama volcanic eraption
Our field surveys were made during 14th to 16th December, 2015 on Hokkaido coast. Fig. 1 shows the result of tsunami height distribution. White circles on the coast show the measured points with high reliability , and black circles show that with less accuracy or reliability.
