i'm phil torres and i'm here with kosta and marita.ow, scientists are detecting millions of earthquakes around the world. what technology do you study to help mitigate them? >> here is san francisco's bay bridge. they absorb the areas of the earthquake while leaving the rest of the infrastructure intact. really, really cool. let's check it out. rising from the san francisco bay is the newest architectural jewel of northern california. the new bay bridge, which connects san francisco and oakland, is now open for business. and what a sight it is to see! roughly 280,000 vehicles travel the east and westbound lanes each day. it's now the widest bridge in direction. this is six years worth of round the clock time lapse video of the new 2.2 mile east span. the project cost $6.4 billion. this is earthquake country. the great san francisco quake of 1906 wiped out 80% of the city. the old bay bridge opened in 1936. and it sits in the worst possible spot: right between two major fault lines. the san andreas and the hayward faults. and the worst-
