September 25, 2003 Tsunami: Hokkaido Island, Japan

Name: September 25, 2003 Tsunami: Hokkaido Island, Japan
Start: 2003-09-25
Location: Hokkaido Island, Japan

September 25, 2003 · 4.4 m · 2 deaths · $90 million · Definite tsunami

A tsunami caused by a magnitude 8.3 earthquake began at Hokkaido Island, Japan on September 25, 2003 at 19:50:06 UTC. The water rose as high as 4.4 meters. Its effects were recorded at 268 places in at least 4 countries. It killed 2 people, counting the earthquake or eruption that caused it.

Travel times

How long the first wave took to reach each part of the ocean, one line for each hour up to 24, estimated from the source and the depth of the sea.

The travel times are computed in your browser, which needs JavaScript.

1 to 4 hours
5 to 6 hours
7 to 14 hours
15 hours and more

Computed in your browser the way NOAA’s own travel time maps are: the wave travels at the square root of gravity times the depth, over NOAA’s ETOPO1 depths averaged to a 10 arc-minute grid. Checked against NOAA NCEI’s maps for 21 tsunamis over the first 24 hours, these lines fall within 10 minutes of NCEI’s at half the points compared and within 52 minutes at 9 in 10. They give when the first wave could arrive, not how high it is; bays, harbors and island chains finer than the grid can see it later. Not for use in a warning: see tsunami.gov.

What the record says

NCEI’s account, from the sources it cites.

Reference #1053:

A tsunami was generated with a maximum wave height of

4 meters along the southeastern coast of Hokkaido.

Reference #3819:

26 September, 2003. A large Tokachi-oki earthquake occurred at the southern coast of Hokkaido, Japan. The earthquake generated large tsunamis causing damage along the southern coast of Hokkaido. The largest tsunami height was 4 m to the east of Cape Erimo, around Bansei-onsen, and locally at Mabiro. The large tsunamis arrived at the Pacific side of the coast of Hokkaido and Tohoku about 2-3 hours after the time of the high tide. In general, the tsunami run-up heights were gradually decreased to the east and to the west away from those two places except Mabiro where the large tsunami height about 4 m is locally observed. The tsunamis generated by the 2003 Tokachi-oki earthquake were observed at tide gauges in eastern Hokkaido and the northern Tohoku regions. The large later phase observed at the tide gauge in Urakawa is the edge wave propagating from Cape Erimo along the west coast of the Hidaka area.

Reference #3819:

At the Tokachi harbor, several cars parked at the quays were washed away by the tsunami. Tokachi harbor was one of the regions most damaged by the tsunami. At thirty survey points in Tokachi harbor, tsunami heights were 2.4-3.2m; these were mostly measured from water lines marked along the buildings or constructions by the tsunami.

The Ootsu harbor is one of the regions most damaged by the tsunami. Several ships collided or were washed away by the tsunamis. The most intensive tsunami survey was conducted in this region. At the northeastern end of the harbor, the tsunami heights were measured from water level lines left by the tsunami on the buildings and other structures. The tsunami heights in the Ootsu harbor ranged 1.8-3.3m, but mostly 2.4-2.9 m.

2003.9.25, Hokkaido Japan event has 1 death and 1 missing. (from Kyodo News of Japan, 2005, in Japanese). (reference #12372)

Injury. Hokkaido: Two people missing [In the vicinity of the mouth of the Tokachi River in Toyoko Town, two anglers (69-year-old male, 66-year old male Sex) is missing (a fire awakening around 16:00 on 26th)], 847 injured people (severe injury 68 people, minor injuries 779 people); Aomori Prefecture: Injured person 1 person (seriously injured 1 person); Iwate Prefecture: Injured person 1 person (slight injury 1 person).
