Scientists Looking at 2012: a Sick Earth or Psychological Imbalance: An Interview with
Professor Li Yonggang, Senior Research Fellow, Southern California Earthquake Center
With earthquake headlines, fears of “super disasters” prevail. Quakes are actually countless but mostly very minor and disable effective
warning on major ones, e.g., Tangshan and Wenchuan had no “introductory shocks”. Lower-class creatures are unlikely to be more
sensitive: the coincidental behaviour and natural phenomena are merely linked retrospectively. Inside the Earth, the Mantle is extremely
hot but the Ocean/Continental Crust is cool; the resultant drift splits and the Continents form. The Lithosphere between the Mantle and
the Crust rupture and volcanoes and quakes result. Major quakes occur once in decades: despite a few “super disasters” throughout
the Earth’s age of 4.5 billion years, she is now maturing into “healthy adulthood”, with even less true disasters. As our 100-year life is
dismal compared with the Earth’s age, the chances of encountering a true disaster is non-existent. To minimize quake impacts, detail
documentation and understanding of the frequency and sites of major quakes, regular drills, e.g., the annual one involving ~10M
people in California are mandatory. The Earth is not “sick” but our minds are: 2012 is OK!
