SUMMARY:Surface Water and Ocean Topography (SWOT) mission
DESCRIPTION:The Surface Water and Ocean Topography (SWOT) mission is a satellite altimeter jointly developed and operated by NASA and CNES\, the French space agency\, in partnership with the Canadian Space Agency (CSA) and UK Space Agency (UKSA). \nThe objectives of the mission are to make the first global survey of the Earth’s surface water\, to observe the fine details of the ocean surface topography\, and to measure how terrestrial surface water bodies change over time. While past satellite missions like the Jason series altimeters (TOPEX/Poseidon\, Jason-1\, Jason-2\, Jason-3) have provided variation in river and lake water surface elevations at select locations\, SWOT will provide the first truly global observations of changing water levels\, stream slopes\, and inundation extents in rivers\, lakes\, and floodplains. In the world’s oceans\, SWOT will observe ocean circulation at unprecedented scales of 15–25 km (9.3–15.5 mi)\, approximately an order of magnitude finer than current satellites. Because it uses wide-swath altimetry technology\, SWOT will almost completely observe the world’s oceans and freshwater bodies with repeated high-resolution elevation measurements\, allowing observations of variations. \nLinks:\nSurface Water and Ocean Topography at NASA.gov \nOcean Surface Topography from Space at NASA.gov \nCnes project Library at CNES.fr \nAVISO+ portal for SWOT

SUMMARY:Mount Lewotobi Laki-laki - eruptions June / July 2025
DESCRIPTION:Lewotobi is a twin volcano located in the southeastern part of the island of Flores\, Indonesia\, it has two peaks; the Lewotobi Laki-laki (Male Lewotobi) and Lewotobi Perempuan (Female Lewotobi) stratovolcanoes\, the more active Lewotobi Laki-laki is about 2.1 km northwest of the taller Lewotobi Perempuan. \nOn 21 March\, Lewotobi Laki-laki erupted\, sending ash clouds over 8 km high. Authorities raised the alert to the highest level\, and Jetstar canceled some flights to Bali. The eruption followed smaller ones since 13 March. One person was injured during the evacuations\, although the details reported were unclear. Bali airport remained open\, but seven international flights were canceled. The geological agency warned of lava floods and continued activity. Lewotobi Laki-laki erupted again on 18 May\, prompting authorities to raise Indonesia’s highest volcanic alert level. Lewotobi Laki-laki erupted on 17 June\, sending ash clouds 11 km high\, prompting authorities to raise Indonesia’s highest volcanic alert level again\, with a plume visible from a distance of 90 km to 150 km. Multiple flights were cancelled due to the amount volcanic ash released into the atmosphere. Two major eruptions occurred on 7 July\, ejecting debris as far as 8 km away and producing pyroclastic flows that reached 5 km from the crater and an ash cloud 13 km high. At least 24 flights were cancelled in Bali. \nLinks:\nIndonesia’s Mount Lewotobi Laki-laki spews 11 kilometre high ash cloud after eruption \nAlert raised to the highest level after Indonesia’s Mount Lewotobi Laki Laki volcano erupts \nIndonesia volcano spews ash more than 6 miles into sky\, dozens of Bali flights canceled \nLewotobi – Pusat Vulkanologi dan Mitigasi Bencana Geologi

SUMMARY:#10April #InternationalDayOfVolcanoes #JournéeInternationaleDesVolcans #GiornataInternazionaleDeiVulcani #DiaInternacionalDeLosVolcanes – petition 2025
DESCRIPTION:Petition proposing an ‘International Day of Volcanoes’ to be observed officially by the United Nations and we are asking that the U.N. General Assembly please consider a resolution for establishing an ‘International Day of Volcanoes’ on 10th April every year. \nTanguy De Saint-Cyr\, owner of French volcano tour company\, that came up with the concept for an ‘International Day of Volcanoes’ and Jeannie Curtis\, a New Zealand technical writer and educator are proposing an ‘International Day of Volcanoes’ to be officially recognised and observed by the United Nations and ask that the General Assembly please consider a resolution for establishing an ‘International Day of Volcanoes’ on 10th April. The date of 10th April has no recognised international day and we propose this date for the following reason: On 10 April 1815 Gunung (Mount) Tambora in Indonesia erupted and generated massive pyroclastic flows and tsunami that instantly killed 10\,000 locals\, who were unaware of the danger. The massive eruption injected huge amounts of aerosols into the Earth’s stratosphere\, causing a global haze which reflected back the incoming sunlight and cooled our planet by half a degree (celsius). This affected the planet’s climate for three years\, causing crop failure and famine\, resulting in up to 60\,000 more human deaths globally – as well as affecting animals\, fauna and agriculture. Tambora is still the deadliest eruption in recorded history\, and 10th April is a date in which the people of the World can reflect upon an “International Day of Volcanoes’ \nLinks:\nSUPPORT a proposal to United Nations for an ‘International day of Volcanoes’ to be recognised on 10th April \nInternational Day of Volcanoes

SUMMARY:EGU General Assembly 2025
DESCRIPTION:The European Geosciences Union (EGU) is a non-profit international union in the fields of Earth\, planetary\, and space sciences whose vision is to “realise a sustainable and just future for humanity and for the planet“. \nThe organisation has headquarters in Munich\, Germany. Membership is open to individuals who are professionally engaged in or associated with these fields and related studies\, including students\, early career scientists and retired seniors. The EGU publishes 19 public peer-reviewed open-access scientific journals and a number of other science publications. It also organises several topical meetings\, as well training events and summer schools\, and provides support and funding for numerous education and outreach activities. Its most prominent event is the EGU General Assembly\, an annual conference that brings together over 18\,000 scientists from all over the world. The meeting’s sessions cover a wide range of topics\, including volcanology\, planetary exploration\, the Earth’s internal structure and atmosphere\, climate change\, and renewable energies. The EGU has 22 scientific divisions that reflect the interdisciplinary nature of the organisation. The EGU General Assembly 2025 brings together geoscientists from all over the world to one meeting covering all disciplines of the Earth\, planetary\, and space sciences. The EGU aims to provide a forum where scientists\, especially early career researchers\, can present their work and discuss their ideas with experts in all fields of geoscience. \nLinks:\nEGU General Assembly 2025 \nBritish Antarctic Survey scientists lead polar search at key international conference
