Dr. Hiroo Kanamori, Seismologist & Geophysicist, Recognized as the 2015 Marcus Milling Legendary Geoscientist

The American Geosciences Institute is pleased to recognize Dr. Hiroo Kanamori with the Marcus Milling Legendary Geoscientist Medal at the 2015 American Association of Petroleum Geologists Annual Convention and Exposition. Kanamori has been described as "a towering figure in seismology and geophysics."

EARTH Magazine: Hazard Lingers After South Napa Earthquake

After the Aug. 24, 2014, Napa Valley earthquake, movement continued along the principal fault to the north of the epicenter, according to a report released by the U.S. Geological Survey. Such "afterslip" is known from previous quakes, but this is the first time that strong afterslip has been observed in a populated residential community.

The Geoscience Community Honors the Man Who shook Up Earthquake Science

he American Geosciences Institute is honoring one of the scientists who advanced earthquake hazards preparedness and mitigation in the U.S. by his superlative service to the earth sciences. This year’s recipient of the Ian Campbell Medal, Dr. James “Jim” Davis, is one of the key scientists behind U.S. earthquake hazards and loss reduction policy as it is known today.

EARTH Magazine: The Bay Area's Next ''Big One'' Could Strike as a Series of Quakes

Most people are familiar with the Great 1906 San Francisco Earthquake and are aware of the earthquake risk posed to the Bay Area — and much of California — by the San Andreas Fault. Most people are not aware, however, that a cluster of large earthquakes struck the San Andreas and quite a few nearby faults in the 17th and 18th centuries. That cluster, according to new research, released about the same amount of energy throughout the Bay Area as the 1906 quake. Thus, it appears that the accumulated stress on the region’s faults could be released in a series of moderate to large quakes on satellite faults, rather than a single great event on the San Andreas. But how this information might change the hazard forecast for the Bay Area is uncertain, scientists say.

EARTH Magazine: Faking quakes at full scale: Giant shake tables simulate earthquakes to make buildings safer

On a muggy day in mid-July 2009, a lone seven-story condominium complex northwest of Kobe, Japan, was violently shaken by an earthquake. Onlookers watched the 23-unit, wood-frame tower sway and bounce while, inside the building, furniture toppled and plates clattered to the floor. No one was hurt during the highly localized event and there was only minimal damage, in part because the building’s wooden skeleton had been augmented to better resist earthquake shaking, but also because the whole event — from the seismicity to the partially furnished building — was just a test.

EARTH: Highlights of 2011 - New Zealand: after 8,000 aftershocks, when will it stop?

You know you are from Christchurch when you manage to keep your sense of humor through a year of nonstop hardship. This phrase, coined by Christchurch native Bruce Raines, exploded on Facebook and takes on a multitude of equally morose and light-hearted endings. These phrases accurately capture the spirit of the local inhabitants after a series of earthquakes and aftershocks rocked the city, dramatically changing life for all Cantabrians. Homes and historic buildings were leveled, and everyday luxuries such as electricity and plumbing were lost. However, while those of us on the outside watched the disaster unfold for a few days, we were able to safely return to our heated homes and refreshing showers. To this day, many Cantabrians are stuck in a permanent camping mode: boiling water, and using primitive outhouses when available. In the December issue of EARTH magazine, learn more about how the citizens of Christchurch are coping with the disaster, one aftershock at a time."
