Predictable and unpredictable aspects of earthquakes from P-wave onsets of acceleration seismograms

Earth, Planets and Space
It is widely acknowledged that predicting the final size of an earthquake from the P-wave onset in seismograms is nearly impossible. We confirm this fact by measuring the slope (parameter $$B$$ B ) of the acceleration record shortly after onset assuming ...

Potential atmospheric impact of the Toba Mega‐Eruption ∼71,000 years ago [PDF]

, 1996
An ∼6‐year long period of volcanic sulfate recorded in the GISP2 ice core about 71,100 ± 5000 years ago may provide detailed information on the atmospheric and climatic impact of the Toba mega‐eruption. Deposition of these aerosols occur at the beginning

Five Large 13th Century C.E. Volcanic Eruptions Recorded in Antarctica Ice Cores

Atmosphere
Major explosive volcanic eruptions impact the climate by altering the radiative balance of the atmosphere and through feedback mechanisms in the climate system.

Modelling of bubble nucleation in trachy-phonolitic magmas: implications for the dynamics of ash-rich eruptions [PDF]

, 2012
Nucleation of water gas bubbles in trachyphonolitic magmatic melts has been investigated integrating theory and numerical modelling with decompression experiments and analysis of natural ash samples of explosive eruptions.

Highly Systematic Response of Seismic Rupture Patterns to Background Loading Rate: Insights From Repeating Earthquakes

Geophysical Research Letters
Although earthquakes are known to recur in approximately the same areas, their recurrence patterns and final sizes can vary considerably. To understand this variability, we analyzed a prominent sequence of repeating earthquakes from the latest catalog in

Upper-atmosphere Aerosols: Properties and Natural Cycles [PDF]

, 1992
The middle atmosphere is rich in its variety of particulate matter, which ranges from meteorite debris, to sulfate aerosols, to polar stratospheric ice clouds. Volcanic eruptions strongly perturb the stratospheric sulfate (Junge) layer.
