White Island Volcano Case Study
The uninhabited island covers an area of approximately 325 ha (800 acres), which is only the peak of a much larger submarine volcano. White Island is privately owned. It was declared a private scenic reserve in 1953. Visitors cannot land without permission, however, it is accessible by authorised tourist operators by boat and helicopter.

The Hunga Tonga-Hunga Ha'apai (HTHH) volcano (20.536°S, 175.382°W) is an underwater caldera volcano located ~70 km north-northwest of Tonga's capital, Nukualofa. Recent Surtseyan-style eruptive activity was observed in 2009, from 2014 to 2015, and from 20 December 2021 to 15 January 2022 ( 17 ). In the lead-up to the 15 January 2022 ...
Report on La Palma (Spain)
Seismic events at La Palma during 12-19 September 2021 showed distinct changes during those days. During 12-14 September (left) the seismicity migrated westward and was located at depths of about 7-13 km. The color scale on the left indicates the time of the events in hours before 0925 on 14 September, with red as the most recent.

Impact of the Hunga Tonga volcanic eruption on stratospheric
The Hunga Tonga-Hunga Ha'apai (HTHH) volcanic eruption (20.54° S, 175.38° W) on 15 January 2022 produced a shock wave felt around the world and released more water vapor into the stratosphere than any other volcano on record (2, 3).The powerful eruption sent aerosols, gases, and water in both vapor and condensed phases into the stratosphere with some material reaching over 56 km high into ...

Barren Island volcanism and seismicity: An intriguing finding
The Barren Island volcano is the part of the Neogene Inner Volcanic Arc (NIVA) (Mitchell 1985; Halder et al. 1992) which extends from the Mt. Popa and Mt. Wuntho (extinct volcanoes) in Myanmar in the north to the Sumatra and Java in the southeast and intersects the Pacific Ring of Fire (figure 3).This volcanic arc is related to the subduction of Indo-Australian plate beneath the SE Asian plate ...

Monitoring Active Volcanoes: Some Case Studies
Investigations carried out as part of the USGS Volcano Hazards Program provide case studies of monitoring two of the world's most active and best understood volcanoes, Mauna Loa and Kilauea on the "Big Island" of Hawaii.Since 1980, the USGS has expanded its monitoring studies to include other volcanoes in the United States and, in cooperation with foreign scientists, in a few other countries.
