The much expanded sixth edition of Environmental Hazards provides a fully up-to-date
overview of all the extreme events that threaten people and what they value in the 21st …

Occurrence of large earthquakes close to cities in California is inevitable. The resulting
ground shaking will subject buildings in the near-source region to large, rapid displacement …

We combine 6 years of Global Positioning System (GPS) data with 20 years of trilateration
data and a century of triangulation, taped distance, and astronomic azimuth measurements …

In this release of hazard maps we present numerous maps and data with varying
parameters. The computations for these maps and data used 50 year return periods on firm …

High-rise flexible-frame buildings are commonly considered to be resistant to shaking from
the largest earthquakes. In addition, base isolation has become increasingly popular for …

Abstract After the 1987 Whittier Narrows and 1994 Northridge earthquakes revealed that
blind thrust faults represent a significant threat to metropolitan Los Angeles, a network of 250 …

It is well established that sedimentary basins can significantly amplify earthquake ground
motion. However, the amplification at any given site can vary with earthquake location. To …

Estimates of surface rupture displacement and magnitude for crustal earthquakes from the
preinstrumental era (pre-1900) tend to be greater than the corresponding estimates derived …

Changes in stress in southern California are modeled from 1812 to 2025 using as input (1)
stress drops associated with six large (7.0≤ M< 7.5) to great (M≥ 7.5) earthquakes through …

Paleoseismological data suggest the occurrence of four bursts of seismic moment release in
the Los Angeles region during the past 12,000 yr. The historic period appears to be part of …
