Puerto Rico, which has been experiencing seismic activity since late December, was rocked Jan. 6 and 7 when a pair of strong earthquakes took down buildings and caused widespread power outages, according to news reports.
A magnitude 7.1 temblor struck northeast of Los Angeles on Friday, July 5 at 8:19 p.m., a day after a 6.4 magnitude rocked the same area, knocking out power to thousands and prompting questions on proper calibration of a recently introduced earthquake early-warning system.
More than failed tsunami warning systems, earthquake experts condemn a lack of public understanding of the risk as a fatal contributor to the more than 1,400 deaths in a 7.5-magnitude earthquake and tsunami that hit Palu Bay in Sulawesi, Indonesia, on Sept. 29.
Gov. Jerry Brown (D) in late September vetoed a bill that would have directed California municipalities to create a database of structures that would be at risk of collapse as a result of seismic events.
A magnitude 6.7 earthquake occurred on the northern Japanese island of Hokkaido on Sept. 6, leaving at least seven dead and damaging buildings and structures in the region, including a 1,650MW coal-fired thermal power plant that was taken offline.
Hundreds of low-intensity earthquakes near the surface of a northern coastal region of the Netherlands have prompted the government to consider scaling back gas extraction, likely by several billion cubic meters a year.
A new study of high-sensitivity gravimeter and seismometer data—recorded just before and during the magnitude-9.0 earthquake on March 11, 2011, in Tohoku-Oki, Japan—describes a promising new data collection and analysis methodology that could give authorities time to issue advance warnings and secure vulnerable systems before earthquakes strike.
Structural engineer Cary Kopczynski once penned a prediction: “There may come a day in the not-too-distant future when concrete building structures will commonly be reinforced with a combination of steel fibers and steel reinforcing bar.
Since Los Angeles joined San Francisco Bay Area cities last October in tightening seismic standards for non-ductile concrete buildings and multi-family, wood-frame structures with parking underneath (ENR 11/9/15 p. 16),
seismic retrofit work in those cities has been booming.
