![]() | The title of the 1925 article published by Kiyoo Wadati, distinguished Japanese seismologist, is "On Mohorovičić Wave appeared in Tazima-Earthquake", published in the Journal of the Meteorological Society of Japan in No. 8, 1925. It is indeed a big surprise to see such an echo of Mohorovičić's pioneering work in seismology. As we can see, his name appears already in the title of the article. The MOHO discontinuity, the notion now in current use throughout the world, has been discovered in Zagreb by this great scientist in 1909. |
From the abstract of the article: "Some seismograms of the destructive earthquake occurred on May 23rd, 1925 in North Tazima district, show distinctly so-called the Mohorovičić wave. One of them is shown in Fig. (4) magnified from the seismograms of Wiechert's 200kg. seismograph installed at the Central Meteorological Observatory in Tokyo. (Epicenter distance about 450km.) ..."
Note that the name of Mohorovičić appears already in the title.
