Through telework and other adaptations we continue to maintain our monitoring networks and analysis of the incoming data. Volcano Observatories Continue Operations Amid COVID-19The five volcano observatories of the USGS Volcano Hazards Program continue to monitor the volcanoes of the United States and issue forecasts and regular updates of volcanic activity. Here's how we can support them, delves into topics such as infrastructure donation, research and operational motives, and training of observatory staff, while maintaining the key goal of supporting the autonomy and authoritative role of the local observatory. The article, Volcano observatories reduce risk around the globe. Two scientists from the USGS Volcano Disaster Assistance Program (VDAP is funded largely by USAID) penned a short overview of ways that different entities such as academia, governments, NGOs, and the global insurance industry can work together to bolster global resilience to volcanic disasters through support of front-line science institutions, like volcano observatories. One way to keep everyone secure is to ensure that volcano observatories around the world have the expertise and resources to detect and forecast volcanic activity, and can provide useful warnings and messages used by both local and global populations. It was like hyper-fuel for a mega-thunderstorm," Bedka said, adding, "The plume went 2.5 times higher than any thunderstorm we have ever observed, and the eruption generated an incredible amount of lightning.When a volcano erupts, there can be global ripples caused by interruptions of air travel, agriculture, and tourism. "The combination of volcanic heat and the amount of superheated moisture from the ocean made this eruption unprecedented.
It's a technique they developed to study severe thunderstorms in the stratosphere.
They ran an algorithm that compared the images from the satellites, and the different angles at which they were taken, to construct a 3D profile of the plume. To map the ash plume from the initial eruption, Bedka and his NASA colleague, Konstantin Khlopenkov, used images from the two satellites, the same way our brains use images from our two eyes. The World Bank estimates that the event caused $90.4 million in damages - 20% of Tonga's GDP. Three people died in the aftermath of the eruption.
That land was uninhabited, but the eruption and the tsunami it triggered destroyed homes, boats, and fisheries in populated islands nearby, and severed the undersea internet cable that keeps Tonga online. Nearly a decade of low-level volcanic activity culminated in a series of violent eruptions in January, which wiped out the newborn island and took off large chunks of Hunga Tonga and Hunga Ha'apai.
