Immigration Nation: Research and Experts
Newswise

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.

Creating a Tsunami Early Warning System Using Artificial Intelligence
American Institute of Physics (AIP)

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.

Unstable Rock Pillars Near Reservoirs Can Produce Dangerous Water Waves

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.
