1. Figure 1 - Possible inflation of Augustine (about 2 cm, outlined in white) during August – October 2005, before the Jan 2006 eruptions. Atmospheric artifacts are visible on the eastern flank of the volcano.

2. Inflation of 2-4 cm Figure 2 – Inflation (right panel) associated with magmatic intrusion at Tanaga volcano, in the western Aleutian arc, likely associated with a seismic swarm during September-October 2005 (left panel). InterferogramSeismicity

3. Figure 3 - InSAR results from Uzon volcano, Kamchatka Peninsula, showing inflation during 2000-2003. Each color cycle represents 2.8 cm of line-of-sight surface displacement. Kamchatka Peninsula

4. Figure 4 - Complex pattern of deformation revealed by an ENVISAT interferogram spanning 2004-5. Inflation of the entire caldera is apparent, as is subsidence of the Norris thermal area, which had been inflating in the early 2000s. caldera inflation Norris subsidence

5. Figure 5 - Observed (left), modeled (center), and residual (right) line-of-sight displacements around Mount St. Helens. The model includes a point source at 12 km depth with a volume loss of 27 million cubic meters.

6. inflation subsidence KILAUEA MAUNA LOA Figure 6 - ENVISAT interferogram spanning November 2003 to January 2006 and showing inflation of the summits of Kilauea and Mauna Loa volcanoes, along with subsidence along both of Kilauea’s rift zones.

7. Figure 7 - ENVISAT interferogram spanning July 2003 to December 2005, showing small patches of subsidence at Kilauea volcano. At Alae and Makaopuhi, the subsidence may be related to large masses of cooling lava when the craters were filled in the 1970s. The deformation mechanism in the north caldera is unclear. north caldera Alae crater (former site) Makaopuhi crater KILAUEA CALDERA EAST RIFT ZONE
