The Indiana Geological Survey is helping students (and news reporters) learn about the earthquake history of Indiana and experience simulated ground shaking of up to magnitude
Earthquakes and tsunamis are great motivators, as are the pursuits. These are the reasons why a lot of time and resources have gone into studying the seismic, geodynamic, and hydrothermic systems in the Pacific Northwest.
The Global Positioning System has completely revolutionised how geologists study the deformation of the Earth. If you leave a GPS receiver in a fixed location for days, months and years, it is precise enough to measure motions on the millimetre … Continue reading
The high alert at Mexico’s Popocatépetl remains in place as the restless Mexican volcano still shows signs that new magma is at the surface, meaning a larger explosion could occur if pressures builds under the summit crater. Over the last
Last night a earthquake swarm started on the Reykjanes Ridge, this earthquake swarm started slowly with just few minor earthquakes. It however did pick up later today with stronger earthquakes and more activity. Strong earthquakes in this swarm so far … Continue reading
On April 30th, 2013, the Haiti Research and Policy Program’s Dialogue Series welcomed Sophia Stranksy, CEO of the Digicel Haiti Foundation to discuss the foundation’s primary education and youth programs. The discussion also explored the potential for real-time low-cost mobile phone based monitoring systems to track the impact of education programs on student’s overall learning,
“If you’re not on a fault zone, a volcanically active zone, or a tsunami zone, you’re probably in a valley that’s prone to flooding or having things tumble down the hills towards you.” So opines risk consultant Tony Taig in … Continue reading
As always I need donations, since its cost to run this web page and there is a lot of work put into writing on this blog. Monitoring earthquakes and checking data, science studies and so on. Since I run my … Continue reading
Today (04.05.2013) at 05:06 UTC a magnitude 1.5 earthquake took place in Hekla volcano. This earthquake had the depth of 7.8 km. No other earthquakes have so far taken place following this earthquake and no change has taken place in … Continue reading
Yesterday (02.05.2013) at 06:08 UTC there was a earthquake swarm deep off the south coast of Iceland. This earthquake swarm was around 300 km south of Iceland. I do not know if there are any volcanoes in this area, at … Continue reading

The last decade has witnessed two unusually large tsunamigenic earthquakes. The devastation from the 2004 Sumatra–Andaman and the 2011 Tohoku-Oki earthquakes (both of moment magnitude ≥ 9.0) and their ensuing tsunamis comes as a harsh reminder on the need to assess and mitigate coastal hazards due to earthquakes and tsunamis worldwide.
Most homeowners insurance policies have exclusions that make them worthless when the home is damaged by common geologic problems such as floods, earthquakes, landslides, mine subsidence, cavern collapse and expansive soils. When a home is damaged the homeowner often is surprised that his “all perils” policy has these
On Saturday morning local time (Friday evening for us in the USA), a magnitude 6.6 earthquake shook up Sichuan province in western China, about 35 km north of the closest city, Ya’an, and 115km west of the provincial capital Chengdu. … Continue reading
“We detected seismic waves created by the oceans waves both hitting the East Coast and smashing into each other,” with the most intense seismic activity recorded when Sandy turned toward Long Island, New York and New
You have probably heard of the Richter Scale for measuring earthquakes, the Saffir-Simpson Scale for hurricanes and the Fujita Scale for tornadoes. The Volcanic Explosivity Index is used to compare the size of explosive volcanic
Squashed and squeezed between the Eurasian continent to the north and the northward-moving Arabian plate to the south, it is no surprise that Iran is a seismically active country, and in the past week it has been living up to … Continue reading
USGS reports that a magnitude 7.8 earthquake occurred in Iran at about 3:14 local time. A BBC article reports on how the earthquake was felt in various parts of the Middle
Send to KindleAround 11:00 UTC a earthquake swarm started just north of Kolbeinsey island. This earthquake swarm looks rather powerful. But due to distance from land only the largest earthquakes are appearing on the SIL network and on my geophone … Continue reading
Send to KindleYesterday (09.April 2013) there has been less activity in Tjörnes Fracture Zone. The largest earthquakes yesterday did have the magnitude 4.0 and 3.3. A smaller earthquake with the magnitude 3.1 also took place. Many other smaller earthquakes also … Continue reading
I'm only reporting these earthquakes when they get to M4. Unlike the Alaska cluster, these seem to be very closed at the M3-ish level. That is very non-fractal, so it could be deep fluids. If these earthquakes start curving around Anguilla, then there is a clearer mechanism. There has been lots of earthquake action in the past
And looking at this, I'm probably blowing smoke about
