根据近海波浪计、GPS浮标、有线海底压力计和海啸浮标记录的海啸到达时间估算，2011年东北太平洋沿岸地震产生的海啸源区长约500公里，最宽约200公里。 2011年海啸震源区包括此前多次发生大地震的几个区段。然而，日本海沟大段的北部和南部不包括在源区中。日本海沟段的房总半岛南部部分有可能在不久的将来引发大海啸地震。
The source area of the tsunami generated by the 2011 off the Pacific coast of Tohoku Earthquake estimated from tsunami arrival times recorded at offshore wave gauges, GPS buoys, cabled ocean-bottom pressure gauges, and tsunami buoys is about 500-km long with a maximum width of approximately 200 km. The 2011 tsunami source area includes several segments of previous recurring large earthquakes. However, the northern and southern parts of the large Japan Trench segment were not included in the source area. The southern off-Boso-Peninsula part of the Japan Trench segment has the potential to generate a large tsunami earthquake in near future.
