Irrigation significantly exacerbated the earthquake-triggered landslides in Palu, on the Indonesian island of Sulawesi, in 2018, according to an international study led by Nanyang Technological University, Singapore (NTU Singapore) scientists.

On 22 December 2018, a flank of the Anak Krakatau plunged into the Sunda strait between the Indonesian islands of Sumatra and Java, triggering a tsunami that killed 430 people. An international research team has now shown that the volcano produced clear warning signals before its collapse. The researchers recommend to use their study to improve monitoring of volcanoes.

Reporting on 10 years of Deep Carbon Observatory research, scientists say. Just two-tenths of 1% of Earth's total carbon is above surface; Human CO2 emissions are now 40 to 100 times greater than nature's; And a handful of events over Earth 4.5 billion year existence -- immense magmatic eruptions and meteor impacts -- have caused catastrophic volumes of carbon out-gassing, leading to a warmer atmosphere, acidified oceans, and mass extinctions

Using an automated method to create a high-resolution map of the seismic velocity below the seafloor, researchers from Kyushu University found a large-scale gas reservoir in an area where the Earth's upper layers are being separated. This reservoir, the first of its kind, and the potential for others like it could have implications from natural resource or environmental standpoints depending on whether the trapped gas is methane or carbon dioxide and whether it remains trapped.
