Erik Klemetti has posted a fascinating article about new research at Lassen Peak. He describes work yielding insights into developments within a magma chamber in the years between eruptions. Erik and his undergraduate students at tiny Denison College (Granville, Ohio) looked at tiny zircon crystals preserved in lava that erupted in 1915 and also the 27,000-year-old Chaos Crags lava. If nothing else grabs you in his short post, you’ll get to read about the “Bumpass Sequence”,and why the “blob from hell” magma model just may be obsolete.
