New earthquake hazard maps from the U.S. Geological Survey show increased earthquake risk areas beyond typical hotspots like California. Geologists say planners and local officials should react to the maps by updating building codes.
"The maps by the U.S. Geological Survey (USGS) reflect the discovery of more earthquake faults in California, a new 7.4-magnitude-quake risk in Utah, as well as more ways to rock the Midwest, South Carolina and the Pacific Northwest than you can shake a stick at."
"Unlike last week's forecast of possible ruptures along faults in California, the National Seismic Hazard Maps calculate the likely intensity of shaking at any given location -- caused by any regional fault giving way -- over a period of 50 years."
"As a result, the new maps are vital for updating local building codes and a direct response to the old geologist truism: Earthquakes don't kill people, buildings kill people."

When the Earth Turns to Liquid
A 7.5 magnitude earthquake struck the Indonesian island of Sulawesi on Sept. 25, followed by a massive tsunami. Soil liquefaction caused by the tremor resulted in 1,700 homes being "swallowed" as the soil shifted. Deaths exceeded 1,400 on Oct. 3.

As the death toll from Mexico's 7.1 magnitude earthquake on Sept. 19 climbs above 300, the San Francisco Chronicle investigates how well prepared the Bay Area is for an earthquake of comparable magnitude. Not very well.
Mexico City Earthquake Should Raise Questions About Building Safety
The epicenter of Tuesday's quake was in the state of Puebla, 80 miles southeast of Mexico City. Soft soil and unreinforced buildings magnified the damage. The quake comes two weeks after an 8.1 quake struck off the coast of the state of Oaxaca.
