Interviews of the residents and measurements of tsunami trace height revealed only a small seismic intensity in a sharp contrast with a large tsunami. Tsunami height of 2-10 meters above mean sea level was obtained along the whole Nicaraguan coast, although the seismic intensity was only 2 or 3 in the modified Mercalli scale. The small seismic intensity suggests that the present event was a tsunami earthquake characterized by small excitation of short period seismic wave in comparison with large excitation of the tsunami.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"127068","nameIdentifierScheme":"WEKO"}],"names":[{"name":"ABE,
