Frost rings in trees as records of major volcanic eruptions

  title={Frost rings in trees as records of major volcanic eruptions},
  author={Valmore C. Lamarche and Katherine K. Hirschboeck},
New data about climatically-effective volcanic eruptions during the past several thousand years may be contained in frost-damage zones in the annual rings of trees. There is good agreement in the timing of frost events and recent eruptions, and the damage can be plausibly linked to climatic effects of stratospheric aerosol veils on hemispheric and global scales. The cataclysmic proto-historic eruption of Santorini (Thera), in the Aegean, is tentatively dated to 1628–26 BC from frost-ring… 
Dendroclimatological Evidence for Major Volcanic Events of the Past Two Millennia
Several tree ring studies have documented the spatial patterns of climatic effects following major volcanic episodes. Frost rings, micro- or narrow rings and light density latewood rings have all
Tree-ring evidence for climatically effective volcanic eruptions
Abstract Ringwidth variations from temperature-sensitive upper timberline sites in the Sierra Nevada show a marked correspondence to the decadal pattern of volcanic sulfate aerosols recorded in a
The timings of many historic volcanic eruptions coincide with sulphuric acid maxima in polar ice cores and transient cooling events. Similar effects are recorded in ancient ice cores and tree-ring
Volcanic Eruptions over the Last 5,000 Years from High Elevation Tree-Ring Widths and Frost Rings
Some tree-ring records, due to their great age, the annual resolution of their dates, and their sensitivity to the climatic effects of large volcanic eruptions, are useful in understanding the
Dendroindications of recent volcanic eruptions in Kamchatka, Russia
Abstract Precisely dated tree-ring sequences of larch (Larix cajanderi Mayr) extending from 1801–1980 ad from Kamchatka lying in the far east of Asian continent were studied to see the influence of
Tree-Ring Evidence for the 1913 Eruption of Volcán de Fuego de Colima, Mexico
Dendrochronological records provide various types of evidence for the impact of volcanic activity, which can then be used to quantify the amount of risk associated with this environmental hazard.
Holocene Eruptive Activity of El Chich�n Volcano, Chiapas, Mexico
Geologic and radiometric-age data indicate that El Chich�n was frequently and violently active during the Holocene, including eruptive episodes about 600, 1250, and 1700 years ago and several
Record of Volcanism Since 7000 B.C. from the GISP2 Greenland Ice Core and Implications for the Volcano-Climate System
Sulfate concentrations from continuous biyearly sampling of the GISP2 Greenland ice core provide a record of potential climate-forcing volcanism since 7000 B.C. with sulfate deposition equal to or up to five times that of the largest known historical eruptions.
Accelerated plate motion and rates of volcanicity as controls on Archean climates
Although vulcanicity is seen as a possible mechanism of climatic change, under present rates of eruptions it is difficult to envisage volcanic activity acting independently of other factors in
Irish tree rings, Santorini and volcanic dust veils
There has recently been renewed interest in the dating of the violent eruption of the Aegean island of Santorini in the second millennium BC, both by its possible effects on tree-ring growth in the


Greenland ice sheet evidence of post-glacial volcanism and its climatic impact
Acidity profiles along well dated Greenland ice cores reveal large volcanic eruptions in the Northern Hemisphere during the past 10,000 yr. Comparison with a temperature index shows that clustered
The possible effects of large 19th and 20th century volcanic eruptions on zonal and hemispheric surface temperatures
Abstract The contribution of volcanic material to the stratosphere from major eruptions within the last two centuries has been estimated using volcanological criteria, including eruption type,
Paleoclimatic Inferences from Long Tree-Ring Records
Tree-ring data contribute to a better understanding of the nature of past climatic variations, and study of the variation of ring-width statistics through time promises to be very fruitful.
The volcanic explosivity index (VEI) an estimate of explosive magnitude for historical volcanism
Knowledge of the frequencies of highly explosive, moderately explosive, and nonexplosive eruptions would be useful in a variety of volcano studies. Historical records are generally incomplete,
Volcanic eruptions in the Mediterranean before A.D. 630 from written and archaeological sources
Written and archaeological sources from the Mediterranean region have been exhaustively searched for evidence of historical volcanism before the year A.D. 630. Volcanic eruptions are identified here
Tree-ring evidence of past climatic variability
The increasingly visible impact of climatic variability on human affairs lends a sense of urgency to the task of better understanding the workings of the Earth's climatic system. Actual instrumental
A climatically responsive tree-ring record from Widdringtonia cedarbergensis, Cape Province, South Africa
The use of dated tree-ring series to reconstruct past climate has received much attention in recent years1,2. The development of long and climatically responsive chronologies in many areas of the
Holocene climatic variations inferred from treeline fluctuations in the White Mountains
Remains of dead bristlecone pine (Pinus longaeva Bailey) are found at altitudes up to 150 m above present treeline in the White Mountains. Standing snags and remnants in two study areas were mapped

After defining the terms commonly used in reporting volcanic eruptions and noting previous approaches to assessment of their magnitudes, this study proceeds to examine aspects of importance, or
Historic eruptions of Tambora (1815), Krakatau (1883), and Agung (1963), their stratospheric aerosols, and climatic impact
Abstract Decreases in surface temperatures after the eruptions of Tambora (1815), Krakatau (1883), and Agung (1963) were of similar magnitude, even though the amount of material (dust and volatiles)
