Puerto Rico tsunami deposit could have come from pre-Columbian megathrust earthquake
Tsunami deposits identified in a coastal mangrove pond in Northwest Puerto Rico could have come from a megathrust earthquake at the Puerto Rico Trench that occurred between 1470 and 1530, according to research reported at the Seismological Society of.....»»
Research reveals new insights into soil liquefaction during earthquakes
Soil liquefaction, a destructive phenomenon occurring during earthquakes, has traditionally been associated with undrained conditions near the earthquake epicenter. However, new research conducted by Dr. Shahar Ben-Zeev at The Hebrew University of Je.....»»
Data show container deposit schemes reduce rubbish on our beaches
Our beaches are in trouble. Limited recycling programs and a society that throws away so much have resulted in more than 3 million metric tons of plastic polluting the oceans. An estimated 1.5–1.9% of this rubbish ends up on beaches......»»

Why the Earth quakes: A closer look at what"s going on under the ground
Earthquakes, large and small, happen every single day along zones that wrap around the world like seams on a baseball. Most don't bother anybody, so they don't make the news. But every now and then a catastrophic earthquake hits people somewhere in t.....»»
Economic relationships in Pre-Columbian Mexico show that Aztec rulers were ruthless exploiters
Spanish conquerors did not themselves bring inequality to the Aztec lands they invaded, they merely built on the socio-economic structure that was already in place, adapting it as it suited their plans. This is the subject of an article by Guido Alfa.....»»
Q&A: What caused Morocco"s earthquake? A geologist studying the Atlas mountains explains
The epicenter of Morocco's devastating earthquake on 8 September was in the High Atlas Mountains, about 71km south-west of Marrakesh. Moina Spooner, from The Conversation Africa, asked Jesús Galindo-Zaldivar, who has been carrying out research on th.....»»

Seismologists use deep learning to forecast earthquakes
For more than 30 years, the models that researchers and government agencies use to forecast earthquake aftershocks have remained largely unchanged. While these older models work well with limited data, they struggle with the huge seismology datasets.....»»
New methodology combines earthquake ground shaking and ground failure for forecasting gas pipeline damage
After an earthquake strikes in an area with a buried gas pipeline network, it can be critical to identify where potential damage to the pipeline might have occurred—especially since these networks can cover hundreds of kilometers and may sometimes.....»»
Icequakes in Antarctica linked to ocean tides
When the ground rumbles in Antarctica, it may be an icequake—like an earthquake but caused by the movement of ice, not rock. A new study by Penn State researchers found that these seismic events are driven by ocean tides at a major ice stream in We.....»»
