Costs and consequences of natural hazards can be enormous; each year more people and infrastructure are at risk. We develop and apply hazards science to help protect U.S. safety, security, and economic well being. These scientific observations, analyses, and research are crucial for the Nation to become more resilient to natural hazards.

Ecosystems throughout the western U.S. are often dependent on a particular fire regime to reduce hazardous fuels and rejuvenate forests or even guide evolution of plant life and regulate ecological communities. Today fire’s role is more complicated. For example, fire can favor invasive plants and these invaders may, in turn, alter the fire regime.

Organisms have different abilities to adapt to disturbances. Some disturbances can be catastrophic to one species and inconsequential to another. Our Forest and Rangeland Ecosystem Science Center (FRESC) scientists are studying the effects of disturbances on species, biogeochemistry, water quality, habitat connectivity and landscape patterns.

In the late summer of 2005, the remarkable flooding brought by Hurricane Katrina, which caused more than $200 billion in losses, constituted the costliest natural disaster in U.S. history. However, even in typical years, flooding causes billions of dollars in damage and threatens lives and property in every State.

A Direct Method for Calculating Instrument Noise Levels in Side-by-Side Seismometer Evaluations

INTRODUCTION The subject of determining the inherent system noise levels present in modem broadband closed loop seismic sensors has been an evolving topic ever since closed loop systems became available. Closed loop systems are unique in that the system noise can not be determined via a blocked mass test as in older conventional open loop...
