Repeating earthquakes discovered in Costa Rica
An open invitation for researchers to use these remarkable Costa Rica quakes as a collaboration laboratory
Two damaging tremors highlight the Philippines’ coast-to-coast earthquake problem
Two deadly and damaging quakes late last month were probably unrelated to each other.
Ten times more earthquakes now detected in Southern California
The authors claim they found dynamic triggering of tiny aftershocks up to 275 km (150 mi)
from an M=7.2 mainshock in 2010, but they have not proved their case.
The 5 worst (and 5 best) places to live in the S.F. Bay Area if the great 1906 earthquake recurred today
While exact repeats of earthquakes are rare, if the 1906 quake did strike again, what will be our excuse for being so unprepared?
Scientific fraud announced in two studies of the 2016 M=7.0 Kumamoto, Japan, earthquake
In one case, the fault rupture and its associated seismicity had been shifted toward a volcano in support of the author’s hypothesis; in the other, seismograms from temporary near-fault stations had been manufactured. In both cases, evaluation committees and universities called for retractions.
Three independent models converge on the high earthquake potential of Los Angeles
A new model joins two others in confirming the hazard posed by the tectonic forces that are squeezing and shearing greater LA.
Seismic warning to India: A shock strikes just north of Delhi
India is one of the countries with the most earthquake-related deaths. Just in the past century, over 100.000 people have died due to earthquakes in the country (Bilham, 2009)
Mexico-Guatemala earthquake, felt by millions, likely triggered by the 2017 megaquake
The megathrust fault lacks large subduction zone earthquakes in this region. What do these extensional earthquakes tell us?
Magnitude 5.7 earthquake strikes in a long-lived gap in great earthquakes
The earthquake is surrounded by recent great quakes; whether one could strike here is uncertain
Strong shaking from central coastal Chile earthquake: What does it reveal about the next megathrust shock?
The Coquimbo region has an unusual, increasing seismicity that may be preparing the area for a very large earthquake – Prof. Raul Madariaga
Seismic swarm hits Hayward Fault: What does it portend?
One may think that these quakes are small, so why do they matter? Why should I care?
What if the Northridge earthquake had struck today, on its 25th anniversary, during the U.S. government shutdown?
The partial shutdown could make things worse
Quake Connectivity: 3 January 2019 M=5.1 Japan shock was promoted by the April 2016 M=7.0 Kumamoto earthquake
Japanese authorities declared the Jan 3 shock to be an independent event; we argue that it was a product of the 2016 quake, which profoundly changed the hazard.
Mt. Etna eruption likely reactivated Fiandaca Fault
In Pennisi, the statue of Saint Emidio, protector from earthquakes, collapsed.
Sunda Strait tsunami launched by sudden collapse of Krakatau volcano into the sea
Tsunami, Eruption, and earthquake risk is not over
Did Tuesday’s M=7.9 Kodiak earthquake nudge the Alaskan Megathrust closer to failure?
The Alaskan Megathrust was responsible for the M=9.2 Good Friday earthquake in 1964.
Which fault ruptured in the M=6.6 Kos-Bodrum earthquake?
While the fault that ruptured in last week’s Kos-Bodrum earthquake is still up for debate, we now know that the M=7.7 earthquake in the Commander Islands ruptured the Bering Fault Zone
14 November 2016 Mw=7.8 New Zealand earthquake shows an uncanny resemblance to the 2015 Nepal shock
At 12:02 a.m. local time, a Mw=7.8 (per USGS), Mw=7.5 (per GNS Science, NZ) earthquake struck New Zealand’s South Island, and caused tsunami warnings to be issued for all of New Zealand’s east coast.
How a M=6 earthquake triggered a deadly M=7 in Japan
It’s been over four months since we wrote about the powerful Kumamoto quake sequence: The 15 April 2016 Mw=6.2 (Mjma 6.5) Kumamoto, Japan, shock, which was succeeded 28 hours later by the very damaging Mw=7.0 (Mjma 7.3) shock on the same fault system. We can now give you a preview of crucial new discoveries by Japanese and other researchers.
Italy earthquake leaves seismic gaps that were last filled by three large earthquakes in 1703
Could this happen again now? As with precursory swarms, progressive earthquake sequences are uncommon.
The Tail that Wagged the Dog: M=7.0 Kumamoto, Japan shock promoted by M=6.1 quake that struck 28 hr beforehand
Was the M=6.1 a foreshock of the M=7.0, or was the M=7.0 an aftershock of the M=6.1?
