Himawari satellite found a series of gravity waves moving towards northwestern Australia over the Indian Ocean on September 11 and 12, 2024.
Model unlocks real-time estimation of large earthquakes and provides earlier warning of tsunamis
Recently discovered speed-of-light prompt elastogravity signals (PEGS) have raised hopes for rapid and reliable estimation of large earthquake magnitude (above M8) to help mitigate the risks associated with strong shaking and tsunamis.
Gemini Observatory records volcanic gravity waves over Hawai’i, U.S.
Hours after the massive eruption at Hunga Tonga-Hunga Ha'apai1 volcano on January 15, 2022, cameras at the Gemini Observatory on Mauna Kea, Hawai'i, U.S. recorded red waves rippling over Hawai'i. "These are gravity waves, a type of atmospheric…
Planetary wave supercharging noctilucent clouds over Antarctica
An atmospheric wave about half as wide as the Earth is supercharging noctilucent clouds (NLCs) in the southern hemisphere, with NASA's Aeronomy of Ice in the Mesosphere (AIM) spacecraft detecting the phenomenon in this series of south polar images from November…
Large ocean swell hits Pacific coast of Central and South America
Strong waves are lashing the Pacific coast from Mexico to Chile since May 2, 2015. According to media reports, at least three people were killed, one is missing and hundreds had to evacuate from the coastline.One person was swept away in Panama by strong waves that prom
Atmospheric gravity waves over the Arabian Sea
On November 15, 2011, the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Aqua satellite passed over the Arabian Sea and captured this true-color image of a large-scale, overlapping wave pattern. The wave pattern is not caused by ocean waves, however.
Meteotsunami hit Indian Morjim and Baga coastal region
The unusual flooding of Morjim and Baga beaches showed signs of respite on Thursday, but a tsunami expert said it may have been caused by a meteotsunami on the lines of a similar phenomenon in Kerala during the past decade. There were no strange meteorological…
