I still try to catch up with all the amazing new stories on earthquakes, tsunamis and paleoseismology that made it to the media last week. Here is #2 on a reviewed tsunami database for Australia.
Australian tsunami database updated
A recent article by Goff & Chagué-Goff (2014) has some bad news for our friends down under. The compilation of known tsunamis that hit Australia now includes 145 events. This is a threefold increase of the numbers that were published up to now. The evidence comes not only from reports and historical sources, but also from paleotsunami research. For a tsunami in 1911 the authors report waves as high as 13 m in Victoria. “The largest historical event in the database is now the 17 July 2006, Java, Indonesia, tsunami that had a run-up height of 7.90 m at Steep Point, Western Australia.” (Goff & Chagué-Goff (2014). Here are a few more details on this event, which occurred after a magnitude 7.7. thrust quake off Java.
New South Wales has seen the most events, but Tasmania and Queensland also experienced a number of tsunamis. The database is likely to grow when more research is done especially on pre-historic paleotsunami events.
