A bicyclist went around the barricades at the California Highway 1 Devil’s Slide Tunnel project after work hours and rode his bike through one of the tunnels, recording video as he went. I don’t advocate that kind of dangerous behavior, but I must admit that it is neat to see a tunnel nearing completion after several years of work. [Source: YouTube]

New Study Shows Odds High for Big California Quakes

California has more than a 99% chance of having a magnitude 6.7 or larger earthquake within the next 30 years, according scientists using a new model to determine the probability of big quakes.
The likelihood of a major quake of magnitude 7.5 or greater in the next 30 years is 46%-and such a quake is most likely to occur in the southern half of the state.
[Editor] At Left: Figure 1. The colors on this California map represent the UCERF probabilities of having a nearby earthquake rupture (within 3 or 4 miles) of magnitude 6.7 or larger in the next 30 years. As shown in the table, the chance of having such an event somewhere in California exceeds 99%. The 30-year probability of an even more powerful quake of magnitude 7.5 or larger is about 46%.

Tunnel Proposed to Link Europe and Africa at Straits of Gibraltar
The proposed railway tunnel will link Spain and Morroco underneath the Straits of Gibraltar. The depth of the straits ranges from 1,000-ft to nearly 3,000-ft. To put that in perspective, the English Channel is only 150-ft deep, and the Chunnel is another 130-ft below the sea floor. (Photo by chodaboy)
