Earthquake Shakes World's Largest Active Volcano: Could the Seismic Event Trigger Tsunamis and Volcanic Eruption?

On the Big Island of Hawaii, a 4.5 magnitude earthquake hit this afternoon, shaking the world's biggest active volcano, Mauna Loa. The quake, which hit at 4:32 p.m. HT / 10:32 p.m. ET at a depth of more than 20 miles, was upgraded from a magnitude 4.1 to a magnitude 4.5 by the USGS. The quake, which was the biggest in the area in over a month and one of the strongest in the previous 12 months, was felt throughout the Big Island.

Drones learned to hear screams from catastrophe victims

Search-and-rescue teams and emergency services actively use drones during operations. Drones conduct reconnaissance, collect terrain data, deliver medicines and essential supplies to the affected areas. They can better reach and cover inaccessible and larger areas than rescuers on the ground or other types of vehicles. Rescuers also equip drones with...

The earthquake that caused the largest wave on record

On the night of July 9, 1958, Alaska’s Lituya Bay suffered one of the most dramatic events in history. An earthquake measuring 7.9 on the Richter scale shook the entire bay. The problem was not only the earthquake itself, but the wave of more than half a kilometer high that it generated. The biggest wave we have on record.

Robotic seafloor geodesy to help earthquake and tsunami monitoring

Nature Reviews Earth & Environment (2021)Cite this article. The largest earthquakes and tsunamis emanate from subduction zones. However, remote sensing measurements used to effectively monitor continental faults, such as synthetic aperture radar (SAR) and global navigation satellite systems (GNSS), are insufficient to unravel the mechanics of submarine faults and megathrusts because electromagnetic waves are quickly absorbed in water. To better understand the fault mechanics of shallow subduction megathrusts, where the largest tsunami waves are triggered, a two-part system combining satellite positioning and acoustic sonar techniques must be deployed. Yet, conducting GNSS-acoustic surveys using research vessels is generally too costly to provide offshore instrumentation on par with land-based networks. Therefore, there is an imminent need for low-cost, low-power alternatives for seafloor geodesy.

Future Drones Could Hunt You By Your Screams

Researchers at Germany’s Fraunhofer FKIE institute are building first responder drones that could track people by their screams. While it’s easy to imagine human-seeking drones in a sci-fi horror movie, Varela says the gadget would be ideal for post-disaster scenarios, such as earthquakes, hurricanes and wildfires. They could hover over an area that rescue crews have difficulty getting to and pinpoint where people may be trapped.

ASCE releases new manual to plan and design for hazards

The American Society of Civil Engineers (ASCE) has released a new manual of practice (MOP), Hazard-Resilient Infrastructure: Analysis and Design, which provides guidance and a framework for creating consistency across hazards, systems and sectors in the design of new infrastructure systems and in enhancing the resilience of existing ones to help to withstand natural disasters such as such as earthquakes, droughts, floods and storms.

The mystery of the deepest earthquakes on Earth

Most earthquakes occur near the Earth’s surface, at a depth of up to approximately 70 kilometers. They occur when stress builds up in a fracture between two blocks of rock, known as a failure, causing them to suddenly slip. However, at greater depths, the intense pressures create too much friction...
