His associate, Emmit Reese, notes that the quake caused no major damage, but seven utility workers are later burned to death in a storm drain at MacArthur Park . One escapes and survives, but is severely burned on one side of his face . As a precaution, Roark tries to halt the subway lines which run parallel to where the deaths took place, but Los Angeles MTA Chairman Stan Olber mulishly opposes, feeling that there is no threat to the trains . Against regulations, Roark and his coworker Gator Harris venture down the storm sewer in the park to investigate . They are nearly burned alive and barely escape with their lives when hot gases suddenly spew out of a crack in the concrete lining and flood the tunnel .

Minutes later, in the La Brea Tar Pits, thick black smoke and ash billows out, with lightning crackling from it . Then, lava bombs burst out of the tar pits, which ignites several buildings . Steam explodes from the sewer system, while a subway train derails underground, Meanwhile in the subway tunnel, the passengers in the derailed subway train are exposed to the severe heat and toxic gases, which causes them all to eventually lose consciousness . </P>
