It feels as if volcanoes in our region are going off at a high rate right now - but it's reasonably normal activity for the "Ring of Fire" belt running around the Asia Pacific.
Seismic shockwaves after a meteorite’s collision could affect systems all over the planet.
Research suggests a new threat to life on Earth from the meteorite's crash: Via seismic waves, the impact triggered massive undersea eruptions, as big as any ever seen in our planet's history.
New research shows the size of man-made earthquakes is linked to how deep industry wastewater is injected into the ground.

While the Montecito, California mudslides took 20 lives, landslides kill far more people in developing countries. Tighter construction standards and early warning systems could help reduce their toll.

How do scientists predict volcanic eruptions? To do so with accuracy, they need to know the individual volcano and its history very well.

Natural disasters are not only bad in the short term. Many families will see their health, well-being and ability to escape poverty affected for decades, and some will be affected for life.
The interests of future holiday-makers are far from important in times of crisis, but tourism is economically key to these countries.
Rescue workers arrive to Juchitán, Oaxaca, which was almost completely destroyed in Mexico’s September 7-8 earthquake.
Shattered by powerful back-to-back earthquakes, Mexico is facing daunting damages across six states. Now Chiapas and Oaxaca, the country's two poorest states, which were hit first, fear neglect.
