Oh my, word. Did you hear it? We received a few emails mentioning it, but NBC 11 confirms:

"As of 4:10 p.m., PG & E activity in the vicinity of California and Drumm streets is disrupting regular cable car service on the California line," read a Muni alert. "Service will be provided by bus shuttles. The 1-California and the 41-Union are switching back at Clay and Drumm streets in both directions. Muni Metro service is not affected."

But that's not the scary part. This is:

This is near the Embarcadero Center, ACLU and Walgreens. There is also a large Wells Fargo branch in the area.

Not Walgreens! Even if it is the not-so-nice Walgreen, which it is, it still pains us deeply. Yuo see, know Walgreens, know peace; no Walgreens, no peace. Anyway, no one was hurt during the underground blast, but the Hyatt was rattled. Details to come.

Update: Here's a shot of the scene just after the explosion. Also, is that Chu standing there? It is! Looks like the ban has been lifted. Happy now?
