I bet a lot of people who read this will think "Who cares about what a fiction writer thinks about the tsunami?"
Here's a bit from his bio that makes his opinions more relevant:
Arthur C. Clarke Biography
--------------------------------------------------------------------------------
Arthur C. Clarke was born in the seaside town of Minehead, Somerset, England on December 16, 1917. In 1936 he moved to London, where he joined the British Interplanetary Society. There he started to experiment with astronautic material in the BIS, write the BIS Bulletin and science fiction.
During World War II, as a RAF officer, he was in charge of the first radar talk-down equipment, the Ground Controlled Approach, during its experimental trials. His only non-science-fiction novel, Glide Path, is based on this work.

In 1945 he published the technical paper "Extra-terrestrial Relays" laying down the principles of the satellite communication with satellites in geostationary orbits - a speculation realized 25 years later. His invention has brought him numerous honors, such as the 1982 Marconi International Fellowship, a gold medal of the Franklin Institute, the Vikram Sarabhai Professorship of the Physical Research Laboratory, Ahmedabad, the Lindbergh Award and a Fellowship of King's College, London. Today, the geostationary orbit at 42,000 kilometers is named The Clarke Orbit by the International Astronomical Union.

In 1954 Clarke wrote to Dr Harry Wexler, then chief of the Scientific Services Division, U.S. Weather Bureau, about satellite applications for weather forecasting. Of these communications, a new branch of meteorology was born, and Dr. Wexler became the driving force in using rockets and satellites for meteorological research and operations.MORE...............
