Webby the method of smoothing or regularization imposed during analysis. At many volcanoes high velocity anomalies are observed in the shallow regions below active areas where conduits, dykes or sills are expected to be present. At other locations low velocity perturbations are seen and interpreted as magma accumulation.

WebAs shown on the right-hand part of Figure 9.1.4, the upper approximately 100 km of the Earth is known as the lithosphere. This includes the rigid upper part of the mantle (or lithospheric mantle) and the crust. The next 150 km is the asthenosphere or low velocity zone (because seismic waves are slowed as they pass through that material).
