As we enter the summer months in the Northern Hemisphere and the possibility of extreme heat becomes more common, it’s important to stay up-to-date on the science of heat waves and take measures to protect ourselves from this growing public health threat.
Sensors that detect changes in atmospheric pressure due to ground shaking can also obtain data about large earthquakes and explosions that exceed the upper limit of many seismometers, according to new research.
Title 42, the United States pandemic rule that had been used to immediately deport hundreds of thousands of migrants who crossed the border illegally over the last three years, has expired. Those migrants will have the opportunity to apply for asylum. President Biden's new rules to replace Title 42 are facing legal challenges. Border crossings have already risen sharply, as many migrants attempt to cross before the measure expires on Thursday night. Some have said they worry about tighter controls and uncertainty ahead. Immigration is once again a major focus of the media as we examine the humanitarian, political, and public health issues migrants must go through.
An early warning system that quickly classifies submarine earthquakes and determines the risk of tsunami events has been developed by scientists at Cardiff University.
In Physics of Fluids, researchers develop an early warning system that combines acoustic technology with AI to immediately classify earthquakes and determine potential tsunami risk. They propose using underwater microphones, called hydrophones, to measure the acoustic radiation produced by the earthquake, which carries information about the tectonic event and travels significantly faster than tsunami waves. The computational model triangulates the source of the earthquake and AI algorithms classify its slip type and magnitude. It then calculates important properties like effective length and width, uplift speed, and duration, which dictate the size of the tsunami.

The Northwest Pacific coast of Mexico is an area struck by large earthquakes and tsunamis as a result of the interaction of two tectonic plates. However, to date, the structure of the continental margin and, therefore, the causes behind the generation of these natural hazards were unknown.

Find out how an NAU team, led by professor Jim Gaherty, will conduct a seismological study of the Cocos tectonic plate deep beneath the Pacific Ocean.
A novel AI-based approach to detect earthquakes early uses prompt elasto-gravity signals, or PEGS, gravitational changes generated by large-mass motion in megaquakes. PEGS carry information about an ongoing earthquake at the speed of light, arriving much faster than even the fastest seismic waves.
Scientists say they have identified the exact mechanism responsible for the exceptional tsunami that spread quickly across the world after the colossal eruption of the Tonga volcano earlier this year.
The 2004 Sumatra earthquake generated one of the most destructive tsunamis ever recorded, with 100-foot waves that killed nearly 230,000 and resulted in an estimated $10 billion in damage.
New research by an international team from 17 countries including Lawrence Livermore National Laboratory (LLNL) scientist Keehoon Kim demonstrates that based on atmospheric pressure waves recorded by global barometers, the Hunga explosion was comparable in size to that of the 1883 Krakatoa eruption.
A new method of detecting mega earthquakes, which picks up on the gravity waves they generate by using deep-learning models created at Los Alamos National Laboratory, can estimate earthquake magnitude in real time and provide earlier warning of tsunamis.
The 12 August 2021 South Sandwich Island earthquake had a surprise hidden within its complex rupture sequence: a slow, shallow magnitude 8.16 subevent that was “invisible” to researchers at first glance.
Researchers from the Oden Institute for Computational Engineering and Sciences and Institute for Geophysics are part of a team developing Science Monitoring and Reliable Telecommunications (SMART) Cables, which will consist of sensors that “piggyback” on the infrastructure of the existing and expanding undersea telecommunications network. The sensors will allow for low-cost global deep ocean observation to detect temperature, pressure, and seismic acceleration.
While the aftermath of an undersea volcanic eruption and the following tsunami garner much attention as the waves crash around inhabited islands, an expert at West Virginia University says the combination of those hard to predict eruptions and climate change will eventually erase island nations and their cultures in the Pacific and western Indian oceans.
University of Miami experts provide insights on the powerful eruption of the Hunga Tonga-Hunga Haʻapai volcano, an event geologists are calling the biggest recorded anywhere in the world in more than three decades.
Since the tsunami that devastated coasts around the Indian Ocean in December 2004 and the Fukushima disaster in March 2011, people worldwide are aware that geological processes in the ocean can cause significant damage.

She is a member of an alliance of professionals who develop mitigation and outreach programs for coastal areas. She is also co-author of a children's book about a tsunami boat called Kamome.
A glacier that had held an Alaskan slope in place for centuries is melting, releasing the soil beneath in what can be described as a slow-motion landslide that could trigger a devastating tsunami, researchers say. In a study published last week, scientists offered some of the first measurements to quantify how the slope is falling there and modeled potential tsunamis.
Thousands of years ago the UK was physically joined to the rest of Europe through an area known as Doggerland. However, a marine inundation took place during the mid-holocene, separating the British landmass from the rest of Europe, which is now covered by the North Sea.
In a new study, published in the journal Nature, an international team of scientists provide the first conclusive evidence directly linking deep Earth’s water cycle and its expressions with magmatic productivity and earthquake activity.
Volcanic tsunamis - those caused by an underwater eruption - are as devastating as they are abrupt. Richards Sunny, a doctoral candidate in the Department of Ocean Engineering, is developing and improving simulations to map, predict and research volcanic tsunamis.
Researchers at the University of Rhode Island (URI) used San Diego Supercomputer Center’s (SDSC) Comet supercomputer to show that high-performance computer modeling can accurately simulate tsunamis from volcanic events. Such models could lead to early-warning systems that could save lives and help minimize catastrophic property damage.
In many coastal zones and gorges, unstable cliffs often fail when the foundation rock beneath them is crushed. Large water waves can be created, threatening human safety. In this week’s Physics of Fluids, scientists reveal the mechanism by which these cliffs collapse, and how large, tsunami-like waves are created. Few experimental studies of this phenomenon have been carried out, so this work represents valuable new data that can be used to protect from impending disaster.
