There’s been a series of non-stop discussion on the recent quake that hit the Visayas these past few days amid the relief and disaster operation conducted at the heavily-stricken areas. I’ve heard facts and non-facts-at-all from radio broadcasters who talked like experts on earthquakes and tsunamis.
I’ve been keeping this manual on “Earthquake and Tsunami” published in 1990 by the Philippine Institute of Volcanology and Seismology (PhiVolcS) that serves as a guide for my news reportage.
Many of the facts in the manual are nowhere can be found in the internet because of the inability of the PhiVolcS to upload it to the cyberspace for some reasons.
One fact that stands out in the manual is the Tsunami map where all of the 27 local tsunamis from 1603 – 1975 are plotted. The map proves the claims of non-experts that tsunamis occur only in open seas are indeed WRONG. The map shows several places in the Philippines with inland seas that were hit by tsunamis. One of which is the coastline of now the Metro Cebu area as indicated in the map. The exact date of this tsunami that hit Cebu once-upon-a-time is not indicated in the map.
