The kinds of geologic hazards that are likely to be experienced
in New Hampshire include floods (both riverine and coastal),
landslides and earthquakes. The New Hampshire Geological Survey
has recently begun focusing its scientific and mapping expertise
to address some of the risks associated with these kinds of
extreme natural events. Flooding is readily acknowledged to pose
the greatest risk to the people and infrastructure of the state.
Consequently, the state of New Hampshire has embarked upon an
initiative to identify areas adjacent to rivers that are
particularly susceptible to erosion and associated bank failures
that can occur during high flow events. The sensitivity to these
risks in New Hampshire was brought home during the major
statewide flood events of 2005, 2006 and 2007. The new
initiative to address these risks is referred to as fluvial
erosion hazards. More information about the fluvial erosion
hazard program in New Hampshire can be found in the DES fact
sheet listed below. The fluvial erosio
