Science without borders: Unravelling the mysteries of Mt. Paektu Volcano, North KoreaDr. James Hammond, NERC Research Fellow, Department of Earth Science and Engineering, Imperial College LondonMt. Paektu volcano (otherwise known as Changbaishan in China) is a stratovolcano on the North Korea/China border.  In the 10th century it was responsible for one of the largest eruptions in the last 2000 years, forming a 5 km wide caldera at the volcano summit with ash fall as far away as [...]

Free book: Catalogue of the geological effects of earthquakes in Spain (in Spanish) [2015-01-12 11:17:37]  recommend  recommend this post  (79 visits) info

Spain may not be as famous for its earthquakes as Greece, Turkey or Italy, but significant events do shake the western part of the Mediterranean, too. Numerous paleoseismological and archaeoseismological studies as well as research on historical quakes have been undertaken on the Iberian peninsula. A new book was now published by the IGME which collects all the information currently available on the geological effects of earthquakes in Spain. The book is in Spanish and available for free [...]

Picture Perfect and Water Wise: Images May Someday Predict the Hazards of Volcanic Gas 

AGU Meetings [2014-12-22 16:03:32]  recommend  recommend this post  (25 visits) info

Earlier this year, superheated water within Japan’s Mount Ontake triggered a hydrothermal explosion. Scientists monitoring the volcano had seen no signs of impending danger. The resulting steam-triggered eruption killed 57 people. Clusters of earthquakes often precede major eruptions of lava and ash. The same is not true for smaller steam-triggered eruptions of gas like the Ontake event. But those are the sorts of events that Társilo Girona would like to predict, and he believes that cameras [...]

Oklahoma - a tale of two earthquakes

Just now we have had an earthquake of M4.0 that almost nobody felt. This was a mostly normal earthquake (tension) with about half being shear. But, earlier, we had an M4.2 that was strongly felt. This was thrust, with a very small hammer zone.  No fault plane solution could be calculated.  Even a 3.6 thrust had a greater narrow intensity than the recent 4.0 Now, the USGS believes

There is lots of talk in northern Arizona these days about earthquakes, since a moderate tremor shook Oak Creek Canyon (above) on Sunday, November 30.This recent event makes me recall the time in 1993 when I taught a course at Yavapai College called "Earthquakes and Volcanoes of Northern Arizona." My research into providing lecture material for the class made me aware how this part of Arizona is very susceptible to strong temblors, as evidenced by a swarm of quakes that occurred near [...]

Seasonal Summary of Earthquakes in Southern Ontario

This is from the Southern Ontario Seismic Network (SOSN) that I helped out with at one time.  It's probably the best seismic network east of California.  Combined with all the deep seismic reflection data, it has helped formulate my ideas of what is happening here and in the States. Note the very tight association with water.  Basically, no water, no earthquakes, with some exceptions. | Impressum
