中文摘要
我们调查了南开海槽沿岸日本西南部岛屿沿岸池塘和湖泊的岩心沉积物,以揭示南开地震的史前证据。海啸事件的平均复发间隔为300-350年。这个值远远大于100-200年的历史事件的值。这一结果表明,只有在沉积物中记录到了较大的南开地震。
英文摘要
We investigated core sediment from ponds and lakes along the coast of southwestern Japanese Islands along the Nankai Trough to reveal pre-historical evidence of Nankai earthquakes. The average recurrence interval of tsunami events were 300-350 years. This value was much larger than the value, 100-200 years, of the historical events. This result implies that relatively large Nankai earthquakes only have been recorded in the sediments.
