Runup Data

The Runup Table summarizes the elevations and inundation distances computed to date. The data are listed from south to north along the coast using the local name for the area. In this table Rmax signifies the runup height at the maximum inundation distance whereas R'max signifies the maximum observed water surface at any location. Lmax refers to the inundation distance onshore (See photo above).

Tsunami Deposits Noted during Surveying.

Observations have been classed as A, B, or C according to the dependability of the data. The term "na" indicates survey data that are not yet available. The runup data have been corrected for the tide difference at the time of measurement and the computed tide at the time of the tsunami. Place names have been abbreviated for insertion into the table. Runup heights generally varied between 2 and 3 m except in areas where there was some topograhy to focus the tsunami.

Although the runup heights were not extremely high, inundation distances were sometimes quite large because of the flat beach slopes. Several of the inundation distances were well over 200 m. In one instance the tsunami inundated an entire isthmus, near El Dorado, approaching from both sides to cover a distance of 1500 m and carrying fishing boats 300 m onshore.
