Caldera
1 reportCaldera is a geological feature interpreted through shape, composition, age, structure, and the processes that formed it. Researchers test interpretations with rock composition, geophysical signature, and geological setting, while incomplete records, model assumptions, and measurement limits constrain certainty.
Coverage places hazards or resource implications; field and geophysical observations; and formation history within the wider context of Caldera. The account anchors formation history in field mapping and uses seismic or geochemical measurements to test whether the pattern extends beyond one dataset; the comparison must account for the fact that subsurface structure is often inferred indirectly and can support multiple models.

Landsat 8 Captures Anak Krakatau Eruption from Orbit
NASA and USGS's Landsat 8 satellite recorded Anak Krakatau's eruption as volcanic gas and ash reached the atmosphere, grounding flights and halting local activity while the volcano remains active
