Document Summary
Lecture 16: tsunami 1 last class: immediate quake impacts. Poorly constructed buildings and buildings on landfill ( made-land ) or alluvial (soft, less dense) plains are destroyed. Land created by sediment deposits from rivers (and alluvial delta, or alluvial plain) acts in a similar way to land created by pushing debris in the ocean. If water is in the sediment, the earthquake causes it to shake and the sediment liquefies. The ground seemed to twist under us like a top while it jerked this way and that, and up and down and every way. remove buildings to create firebreaks. Water pipes had been broken by the quake. Civilian fire brigades brought water to help fight fires (very successful) Explosions (explode buildings) meant to create firebreaks restrict fire from moving severed more water pipes, worsening the situation. Military forces prevented civilian intervention, and used gunpowder to create firebreaks, which caused more fire rebranding earthquake as an ordinary fire.
