Submarine eruption in late March-April 2022
Kita-Ioto (also known as “Kita-Iwo Jima”) is located about 1,100 km S of Tokyo, Japan. It is a highly eroded stratovolcano with a steep-sided cone that rises about 800 m above the ocean surface. Eruptions from the Funka Asane submarine vent, 4-5 km NW of the main cone (figure 1), have been recorded since 1780, characterized by submarine eruptions during 1780, 1880, and 1930-1945, discolored seawater, and some degassing. This report summarizes previous events of discolored water and degassing, and includes a more recent events consisting of an eruption plume and discolored water during March-April 2022. Information for this report comes primarily from the Japan Coast Guard (JCG), the Japan Meteorological Agency (JMA), the Tokyo Volcanic Ash Advisory Center (VAAC), and satellite data.

Summary of activity. Visual observations of discolored water, and later, occasional degassing bubbles have been made at Funka Asane since May 1953 (table 1). Discolored water typically originates from a point source and appears pale green, yellow-green, blue-white, or milky white; on 5 November 2003, for example, discolored bluish-white water was visible from a single point (figure 2). Some of the discolored areas extended in different directions for 10-200 m, the latter of which occurred on 26 January 2000 and 10 March 2003. On 25 January 2000 three points of bluish-white discolored water appeared at 1410-1425. Pumice-like material was observed floating to the NE of the discolored water with a width of over 500 m and a length of 1.5 km. By the 26th during 0925-0930, the three points decreased to two points and the thin, milky white discolored water extended 200 m NNW, and no floating material was observed. On 16 March 2006 bubbles were first observed during 0942-0949. This type of event occurred intermittently through 9 March 2012. During 1330-1334 on 5 August 2021 light blue-white discolored water was reported by JCG to the S of Kita-Ioto. JCG also made observation flights over the area where they noted no activity. These flights were made on 14 June 2005, 26 February 2009, 30 June 2013, 17 August 2015, 24 December 2016, 24 March 2017, 11 December 2017, 18 July 2018, 29 January 2019, 19 November 2019, 8 June 2021, 9 July 2021, 11 November 2021, 27 December 2021, 15 March 2022, and 29 March 2022.

Activity during March-April 2022. A submarine eruption at Funka Asane was reported by JMA based on satellite images at 1800 on 27 March 2022. An eruption plume rose to 5.5 km altitude at 2100 and may have contained some ash (figure 3). By 2330 and through at least 0300 on 28 March, the plume had risen to 7 km altitude, according to HIMAWARI satellite images (figure 3). The altitude of the plume had dropped to 3.6 km at 0820 on 28 March, and by 1420 it was no longer visible. Aerial observations by JCG on 29 March did not detect discolored water or floating objects surrounding Funka Asane.
A small amount of brown floating material was observed during 1329-1400 on 18 April, originating from the N crater, about 5 km SE from Funka Asane, according to observations made by JCG. Some light brown and yellow-green discolored water were seen off the N coast to the W coast of the volcano (figure 4).

Submarine eruption in late March-April 2022
Kita-Ioto (also known as “Kita-Iwo Jima”) is located about 1,100 km S of Tokyo, Japan. It is a highly eroded stratovolcano with a steep-sided cone that rises about 800 m above the ocean surface. Eruptions from the Funka Asane submarine vent, 4-5 km NW of the main cone (figure 1), have been recorded since 1780, characterized by submarine eruptions during 1780, 1880, and 1930-1945, discolored seawater, and some degassing.

On 25 January 2000 three points of bluish-white discolored water appeared at 1410-1425. Pumice-like material was observed floating to the NE of the discolored water with a width of over 500 m and a length of 1.5 km. By the 26th during 0925-0930, the three points decreased to two points and the thin, milky white discolored water extended 200 m NNW, and no floating material was observed. On 16 March 2006 bubbles were first observed during 0942-0949. This type of event occurred intermittently through 9 March 2012. During 1330-1334 on 5 August 2021 light blue-white discolored water was reported by JCG to the S of Kita-Ioto. JCG also made observation flights over the area where they noted no activity. These flights were made on 14 June 2005, 26 February 2009, 30 June 2013, 17 August 2015, 24 December 2016, 24 March 2017, 11 December 2017, 18 July 2018, 29 January 2019, 19 November 2019, 8 June 2021, 9 July 2021, 11 November 2021, 27 December 2021, 15 March 2022, and 29 March 2022.

Activity during March-April 2022. A submarine eruption at Funka Asane was reported by JMA based on satellite images at 1800 on 27 March 2022. An eruption plume rose to 5.5 km altitude at 2100 and may have contained some ash (figure 3). By 2330 and through at least 0300 on 28 March, the plume had risen to 7 km altitude, according to HIMAWARI satellite images (figure 3). The altitude of the plume had dropped to 3.6 km at 0820 on 28 March, and by 1420 it was no longer visible. Aerial observations by JCG on 29 March did not detect discolored water or floating objects surrounding Funka Asane.
A small amount of brown floating material was observed during 1329-1400 on 18 April, originating from the N crater, about 5 km SE from Funka Asane, according to observations made by JCG. Some light brown and yellow-green discolored water were seen off the N coast to the W coast of the volcano (figure 4).

There is no Deformation History data available for Kita-Ioto.
There is no Emissions History data available for Kita-Ioto.
Maps are not currently available due to technical issues.
The maps shown below have been scanned from the GVP map archives and include the volcano on this page. Clicking on the small images will load the full 300 dpi map. Very small-scale maps (such as world maps) are not included.
There are no samples for Kita-Ioto in the Smithsonian's NMNH Department of Mineral Sciences Rock and Ore collection.
Copernicus Browser | The Copernicus Browser replaced the Sentinel Hub Playground browser in 2023, to provide access to Earth observation archives from the Copernicus Data Space Ecosystem, the main distribution platform for data from the EU Copernicus missions. |
MIROVA | Middle InfraRed Observation of Volcanic Activity (MIROVA) is a near real time volcanic hot-spot detection system based on the analysis of MODIS (Moderate Resolution Imaging Spectroradiometer) data. In particular, MIROVA uses the Middle InfraRed Radiation (MIR), measured over target volcanoes, in order to detect, locate and measure the heat radiation sourced from volcanic activity. |
MODVOLC Thermal Alerts | Using infrared satellite Moderate Resolution Imaging Spectroradiometer (MODIS) data, scientists at the Hawai'i Institute of Geophysics and Planetology, University of Hawai'i, developed an automated system called MODVOLC to map thermal hot-spots in near real time. For each MODIS image, the algorithm automatically scans each 1 km pixel within it to check for high-temperature hot-spots. When one is found the date, time, location, and intensity are recorded. MODIS looks at every square km of the Earth every 48 hours, once during the day and once during the night, and the presence of two MODIS sensors in space allows at least four hot-spot observations every two days. Each day updated global maps are compiled to display the locations of all hot spots detected in the previous 24 hours. There is a drop-down list with volcano names which allow users to 'zoom-in' and examine the distribution of hot-spots at a variety of spatial scales. |
WOVOdat
Single Volcano View Temporal Evolution of Unrest Side by Side Volcanoes |
WOVOdat is a database of volcanic unrest; instrumentally and visually recorded changes in seismicity, ground deformation, gas emission, and other parameters from their normal baselines. It is sponsored by the World Organization of Volcano Observatories (WOVO) and presently hosted at the Earth Observatory of Singapore.
GVMID Data on Volcano Monitoring Infrastructure The Global Volcano Monitoring Infrastructure Database GVMID, is aimed at documenting and improving capabilities of volcano monitoring from the ground and space. GVMID should provide a snapshot and baseline view of the techniques and instrumentation that are in place at various volcanoes, which can be use by volcano observatories as reference to setup new monitoring system or improving networks at a specific volcano. These data will allow identification of what monitoring gaps exist, which can be then targeted by remote sensing infrastructure and future instrument deployments. |
Volcanic Hazard Maps | The IAVCEI Commission on Volcanic Hazards and Risk has a Volcanic Hazard Maps database designed to serve as a resource for hazard mappers (or other interested parties) to explore how common issues in hazard map development have been addressed at different volcanoes, in different countries, for different hazards, and for different intended audiences. In addition to the comprehensive, searchable Volcanic Hazard Maps Database, this website contains information about diversity of volcanic hazard maps, illustrated using examples from the database. This site is for educational purposes related to volcanic hazard maps. Hazard maps found on this website should not be used for emergency purposes. For the most recent, official hazard map for a particular volcano, please seek out the proper institutional authorities on the matter. |
IRIS seismic stations/networks | Incorporated Research Institutions for Seismology (IRIS) Data Services map showing the location of seismic stations from all available networks (permanent or temporary) within a radius of 0.18° (about 20 km at mid-latitudes) from the given location of Kita-Ioto. Users can customize a variety of filters and options in the left panel. Note that if there are no stations are known the map will default to show the entire world with a "No data matched request" error notice. |
UNAVCO GPS/GNSS stations | Geodetic Data Services map from UNAVCO showing the location of GPS/GNSS stations from all available networks (permanent or temporary) within a radius of 20 km from the given location of Kita-Ioto. Users can customize the data search based on station or network names, location, and time window. Requires Adobe Flash Player. |
DECADE Data | The DECADE portal, still in the developmental stage, serves as an example of the proposed interoperability between The Smithsonian Institution's Global Volcanism Program, the Mapping Gas Emissions (MaGa) Database, and the EarthChem Geochemical Portal. The Deep Earth Carbon Degassing (DECADE) initiative seeks to use new and established technologies to determine accurate global fluxes of volcanic CO2 to the atmosphere, but installing CO2 monitoring networks on 20 of the world's 150 most actively degassing volcanoes. The group uses related laboratory-based studies (direct gas sampling and analysis, melt inclusions) to provide new data for direct degassing of deep earth carbon to the atmosphere. |
Large Eruptions of Kita-Ioto | Information about large Quaternary eruptions (VEI >= 4) is cataloged in the Large Magnitude Explosive Volcanic Eruptions (LaMEVE) database of the Volcano Global Risk Identification and Analysis Project (VOGRIPA). |
EarthChem | EarthChem develops and maintains databases, software, and services that support the preservation, discovery, access and analysis of geochemical data, and facilitate their integration with the broad array of other available earth science parameters. EarthChem is operated by a joint team of disciplinary scientists, data scientists, data managers and information technology developers who are part of the NSF-funded data facility Integrated Earth Data Applications (IEDA). IEDA is a collaborative effort of EarthChem and the Marine Geoscience Data System (MGDS). |
