Freshly fallen snow on trees and deck. It is lightly snowing.
Map of earthquake epicenters in Colorado 1882-2000. Earthquakes are mostly clustered along the Front Range and through western Colorado, but there are a few small earthquakes in eastern Colorado. Data from USGS: https://earthquake.usgs.gov/earthquakes/search/
Seismic hazard map (peak ground acceleration, PGA) with 475-year return period from Global Earthquake Model (GEM) for South Asia. Seismic hazard amplitudes are indicated by color, with warmer colors (yellow, orange, red) depicting higher hazard. Hazard in Myanmar/Burma includes regions that are among the highest in the region, oriented along north-south lines that correspond to regional faults.

Figure shows two panels, side by side. Left panel shows a cartoon depiction of a subduction zone, with subduction of oceanic plate (left). Right is a map with contours for depths (20, 40, 60 km, left-to-right) to the Juan de Fuca slab from the Slab2 model (https://www.usgs.gov/tools/slab20-interactive-map).
Map of M>5.5 historical earthquakes in the northeastern US from US Geological Survey website. Map shows four events within 100km of today's southern Maine event.
Map of northeastern US showing the rate (number per year) of M>=3 earthquakes in a white-yellow-red color scale. Map also shows epicenters of recorded earthquakes.Inset map shows the rate of M>=5 earthquakes across conterminous US. Northeastern US has low seismicity compared to western US, but earthquakes are not uncommon.
Ground motion contours from M7 Mendocino earthquake, with contours slightly offset to the East, indicating higher ground motions at those sites.
Ground motion contours from the M7 Mendocino earthquake (1-s SA). There is a slight asymmetry or the contours relative to hypocenter location, with them shifted to east and a broadened, cone shape on land.
Slip model for the M7 Mendocino earthquake showing the hypocenter located to the left (west) of most slip.
Photo of a river bank from southwestern Washington showing a thin layer of gray sand with tan-colored soil and vegetation above this layer. The gray sands were deposited by a tsunami following the 1700 Cascadia earthquake. Soils have developed above this layer in the 300+ years since then.
Tsunami awareness sign showing that the site is in a tsunami zone and an arrow pointing towards the evacuation route.
View of Taku Glacier (I think?) terminating in Taku Inlet, with mountains and gray clouds in the background.
Picture of me under my desk at work in Colorado after practicing earthquake drills—Drop, Cover, and Hold on.
Plot of earthquake epicenters overlying hazard estimates from USGS earthquake website.

Map of earthquake epicenters in the region of the 2024 M3.7 Pierre earthquake plotted on top of a long-term forecast rate for earthquakes in the region. Today's epicenter occurs in a region of very low seismicity in the US, with only a few earthquakes having occurred near the epicenter in the past 40 years. Inset map shows US-wide forecast rate of seismicity.
Map shows forecast seismicity rate (M>3) in background with locations of historical earthquake epicenters. Inset map shows forecast seismicity rate of M>5 earthquakes across conterminous US, indicating that earthquakes have occurred near epicentral region, but that historical seismicity rates are low.
