They are defined within an analytic framework based on the semi-classical quantization of Poincaré map in action-angle variables.

"This continues to accumulate in an unstable manner around the crater and in the high parts of the ravines, which could collapse and cause more pyroclastic flows," it said. Fuego is known for its ...

INSIVUMEH warned of potential pyroclastic flows, reminiscent of the cataclysmic 2018 eruption that claimed over 200 lives. Guatemala, roughly the size of Tennessee, hosts 37 volcanoes, though most ...

The volcano, situated near Antigua Guatemala, is emitting ash plumes and displaying unstable lava flows. Authorities are actively monitoring the situation to mitigate the risk of additional ...

This followed some 30 hours of smoke plumes, lava flows and a downward surge of pyroclastic flows, it added. The Fuego volcano is known for its frequent activity. In June 2018, its most violent ...

This triggered a pyroclastic flow a fast-moving, superheated surge of gas and volcanic material sending a dense ash column high into the sky. The lava initially flowed in three directions before ...

"This continues to accumulate in an unstable manner around the crater and in the high parts of the ravines, which could collapse and cause more pyroclastic flows," it said. Around the size of the ...

This followed some 30 hours of smoke plumes, lava flows and a downward surge of pyroclastic flows, it added. The Fuego volcano is known for its frequent activity. In June 2018, its most violent ...

Let’s see why the map of a 2D crystal’s quantum geometry takes a doughnutlike shape called a torus. In general, the repeating patterns in crystals limit the possible states of the electrons inside ...

The Institute also warned of flows of scorching material—known as pyroclastic flows—descending the slopes. Before the increase in activity, the volcano had shown “normal parameters” with “weak to ...
