UPDATE: A transnational Task Force coordinated by the Central Security Service worked with scientists from Star Nations to transmute and render harmless the nuclear wastes dumped in the Farallon Islands Federal Nuclear Waste Dump. This clean-up was completed by the Dec. 31, 2017 deadline and thus there was no 9.6 M Great Quake in the San Francisco area.

[Earlier Provisional Warning:]
On December 31 (2017) San Francisco is set to be shaken by an enormous and highly-destructive Great Quake and tsunami. The Quake's magnitude is to be 9.6 (vastly stronger than the 1906 San Francisco 7.8 Quake.)
A number of structures in the San Francisco Bay Area would fail in a 9.6 quake. For example the Golden Gate Bridge has been retrofitted to withstand an 8.3 quake, but will fail in a 9.6 Quake.
This end-of-December 2017 Quake's epicenter will be located 17 miles west of San Francisco in the ocean floor's Farallon Trench midway to the Farallon Islands. A major tsunami will also be generated.
That rolling Tsunami would surge through the Golden Gate, and fan out across San Francisco Bay, reaching the shorefront of bayfront communities and spreading into San Pablo Bay and Suisun Bay to the north, and lower San Francisco Bay to the south.
That 9.6 Quake's shaking would also collapse some of the fragile earthen levees of several Bay Delta islands to the north, thereby damaging California's through-Delta fresh water conveyance system from Northern California to Southern California. Result: loss of a significant amount of the water relied upon by the Los Angeles-Southern California area and California's key agricultural Central Valley.
The south-bay surge of the tsunami likely would inundate the Bay Area's two major airports (basically at sea level), San Francisco International (SFO) and Oakland International Airports.
Authorities in the greater San Francisco Bay Area should prepare for a large number of Bay Area residents to flee their ruined or damaged homes.
Disaster agencies will be overwhelmed. The enormity of the quake will require those not so nearby to lend a helping hand as well.
However, if U.S. authorities heed this warning and mobilize in time to clean up the damage being done to Earth by the radioactive waste dumped in the Farallon Trench (remove and neutralize that waste), then Earth will not need to generate this enormous Earthquake in an effort to bury and entomb the radioactive waste poisoning the ocean and sea life.
So the principal thing to note is that the great quake and tsunami are conditional. They will or will not happen depending on whether enough humans get serious about this environmental clean-up to get their demands heeded that the Government clean up all that waste. (And ask Star Visitors' technical help.) Otherwise the Farallon Trench will be the epicenter of that Great Quake.
Let's get active and demand that the U.S. Government clean up the Farallon Islands Nuclear Dump now!
