Four Central American countries reveal they are undertaking public tests of a new earthquake-warning system one day before a quake strikes near Nicaragua.

Ground vibrations caused by traffic and industrial work halved globally during the coronavirus lockdown, a study shows. Social distancing, fewer cars on roads and drops in tourism and travel resulted in the longest and most pronounced quiet period of seismic noise in recorded history.  Seismic noise refers to vibrations in the ground, caused by traffic or heavy machinery and natural phenomena such as earthquakes and adverse weather.  Global human-caused (anthropogenic) seismic noise dropped ...

Planet Earth witnessed its quietest period in decades during 2020 as lockdowns significantly reduced human activity and its impact on the planet's crust, according to scientists working on a global study.  An international group of seismologists from 33 countries measured a drop of up to 50 per cent in so-called ambient noise generated by humans travelling and factories humming after lockdowns came into force around the world.
