solid Earth is one of the fundamental components of the Earth system,
and both influences and reacts to forcings from the oceans and atmosphere.
Understanding the dynamics of the solid Earth is critical for developing
an interconnected view of Earth science. The dynamics of the solid
Earth are, in fact, quite varied: tectonic plates shifting, coasts
eroding, and volcanic eruptions occur from geologic timescales to
sudden, catastrophic moments. The manifestation of many of the solid
Earth processes and the influences on the ocean and atmosphere are
the cause of the most dangerous natural hazards we face. Investigating
the behavior of the solid Earth and developing applications to mitigate
natural hazards yield direct societal benefits.
conducted over the past decade have shown that it is possible to
study the dynamics behavior of the Earth from space. Satellite-based
measurements are among the most practical and cost-effective techniques
for producing systematic data sets over a wide range of spatial
and temporal scales. The combination of space-based and surface
measurements has the potential to mitigate the hazards and manage
the risks associated with natural disasters.
activities will contribute substantially to our understanding of
the processes leading to natural hazards. NASA observations and
analyses, integrated into ongoing hazards programs in federal, state,
and international agencies, will reduce the loss of life and property
through improved planning, improved response, and more efficient
