RIVERSIDE, Calif. – Seismologists at the University of California, Riverside studying earthquakes in the seismically and volcanically active Alaska-Aleutian subduction zone have found that “slow earthquakes” are occurring continuously, and could encourage damaging earthquakes. Slow earthquakes are quiet, can be as large as magnitude 7, and last days to years. Taking place mainly at the […]
On average, 40 volcanoes on land erupt into the atmosphere each month, while scores of others on the seafloor erupt into the ocean. A new time-lapse animation uniting volcanoes, earthquakes, and gaseous emissions reveals unforgettably the large, rigid plates that make the outermost shell of Earth and suggests the immense heat and energy beneath […]
Another quake, this one measured at a magnitude of 7.0, struck the Japanese Island of Kyushu this morning, two days after a previous quake measuring 6.2 struck the region, killing nine and inuring over 1,000. This most recent quake struck just eight miles south of the epicenter of the earlier earthquake. For a short time, […]
Millions of people live in dimples on the Earth’s surface — often near the ocean, in lowlands between mountain peaks too rugged and cold. One of these global indentations, Cook Inlet Basin, recently showed another characteristic of the planet’s basins — they quiver like a bowl of jelly during an earthquake. Many people in Anchorage […]
