Our closest planetary neighbor shares a surprising feature with Earth: volcanoes. A new study, published February 1st in the journal Science Advances, revealed interesting new details about the volcanic history of Mars. Thomas Lapen, first author of the paper and Professor of Geology at the University of Houston, told Astronomy that their analysis of Martian meteorites showed that volcanic activity on Mars has been ongoing since at least 2.4 to 0.15 billion years ago—and likely continues today. Given that the meteorites Lapen and his group studied came from a single ejection site on Mars, they reveal over 2 billion years...

“The island has now been elevated by 9 cm due to the magma pressure. Last night there was one quake of 4.4 on the Richter scale, at a depth of 18km, which was also felt on the neighbouring island of La Palma.”

Krakatau Volcano, Indonesia Eruptions from Krakatau volcano, Indonesia have forced the evacuation of tens of thousands residents. Seven districts affected are Kalianda, Rajabasa, Katibung, Sidomulyo, Ketapang, Sragi and Palas. On Monday ash from Anak Krakatau continued to cover residential areas in parts of Banten province and South Lampung. Visual observations showed ash emissions reaching a height of 600 m and drifting east. Ashfall has affected the operation of seismometers on the volcano. Fisherman and tourists are advised to stay at least 2 km from the volcano.

Last time, it killed thousands and changed the weather for five years, now it could be even deadlier...

SANTIAGO, Chile (AP) — The long-dormant Chaiten volcano blasted ash some 20 miles (30 kilometers) into the Andean sky on Tuesday, forcing the last of thousands to evacuate and fouling a huge stretch of the South American continent.A thick column of ash climbed into the stratosphere and blew eastward for hundreds of miles (kilometers) over Patagonia to the Atlantic Ocean, closing schools and a regional airport. Chilean and Argentine citizens were advised to wear masks to avoid breathing the dangerous fallout.Chilean officials ordered the total evacuation of Chaiten, a small provincial capital in an area of lakes and glacier-carved fjords...
