The Tonga eruption explained, from tsunami warnings to sonic booms

Just a few weeks ago, a submarine volcano identifiable by two small uninhabitable islands in the Kingdom of Tonga began to erupt. Its outburst initially seemed innocuous, with ashen plumes and moderate explosions that few people living outside the archipelago noticed.

But in the past 24鈥

Perseverance鈥檚 first major successes on Mars 鈥 an update from mission scientists

In the short time since NASA鈥檚 Perseverance rover landed in Mars鈥 Jezero Crater on Feb. 18, 2021, it鈥檚 already made history.

At the moment, Mars and the Earth are on opposite sides of the Sun, and the two planets cannot communicate with each other. After working nonstop for the past 216鈥

This is what the heat wave did at Mount Baker and what that means for Whatcom County

Bob Mitchell, a professor of hydrogeology at Western Washington University, said that if the planet鈥檚 warming trend continues, Mount Baker鈥檚 glaciers will keep retreating and the Nooksack could become fed by rainfall, rather than by glacial melt.

Earthquake initially centered in Farmington was 鈥榩hantom鈥 but felt real to residents

Jackie Caplan-Auerbach, a seismologist at Western Washington University, explained it this way in a series of Twitter posts:

鈥淟ocation algorithms can sometimes yield an incorrect location, though. This is because they are somewhat tuned to what they expect to record. For example, a鈥

A Burp or a Blast? Seismic Signals Reveal the Volcanic Eruption to Come

Last December, a gloopy ooze of lava began extruding out of the summit of La Soufri猫re, a volcano on the Caribbean island of St. Vincent. The effusion was slow at first; no one was threatened. Then in late March and early April, the volcano began to emit seismic waves associated with swiftly鈥

Will a volcanic eruption be a burp or a blast?

Perhaps monitoring from space will become the best way to see future phreatic eruptions coming. But so far, no successful long-term forecast of a phreatic eruption has taken place. 鈥淧hreatic eruptions are terrifying,鈥 said 鈥
