Roundup of Global Volcanic Activity
Kilauea (Hawai'i): The new active lava flow headed to the southeast from Puʻu ʻŌʻō continues to advance and spread laterally. On 28 July it had reached a length of 6.9 km (4.3 mi) from the vent and reached the Pulama pali in the western area of the abandoned Royal Gardens subdivision. Most likely, it will reach the coastal plain today or in the next days, but then slow down and widen, reducing its advance towards the ocean. At the summit caldera, a phase of deflation is in progress. The level of the Halema'uma'u lava lake dropped by about 10 m (33 ft) during 27-28 June.
Etna (Sicily, Italy): There has been no particular surface activity at the volcano since the violent summit eruptions in late May, but the volcanic tremor amplitude has been gradually rising over the past days. This could [speculation!] indicate a phase of magma migrating to the surface, and possibly herald new activity in the near future. Etna, always good for surprises, will tell.
