Postfire debris flow hazards—Tips to keep you safe
How USGS gages are used in flood forecasting
The U.S. Geological Survey (USGS) operates an extensive nationwide network of stream, rain, and groundwater gages. These instruments are used to monitor how much water there is across the Nation at any given moment. Stream data are collected at streamgages every 15 minutes, transmitted to USGS servers, and updated online in real time. To improve awareness of current water conditions and possible f

When it comes to talking to others, especially when explaining science, the key is consequences outweigh precision. You should always be honest, tell the truth, but don't sweat the small stuff. People care about relatability, not the mundane. Knowing what information isn't worth sharing is hard. There are professionals out there who can help. Like me.

On February 6, 2023, magnitude 7.8 and 7.5 earthquakes struck Turkey near the Syrian border. Over 50,000 people lost their lives. Earthquake shaking was not the only hazard. The quake triggered landslides, liquefaction, and other cascading hazards.

Rockfalls are abrupt movements of masses of geologic materials, such as rocks and boulders, which become detached from steep slopes or cliffs. Separation occurs along discontinuities such as fractures, joints, and bedding planes, and movement occurs by free-fall, bouncing, and rolling.

TYPES OF LANDSLIDES
Toppling failures are distinguished by the forward rotation of a unit or units about some pivotal point, below or low in the unit, under the actions of gravity and forces exerted by adjacent units or by fluids in cracks.
Toppling failures are distinguished by the forward rotation of a unit or units about some pivotal point, below or low in the unit, under the actions of gravity and forces exerted by adjacent units or by fluids in cracks.
Lateral spreads are distinctive because they usually occur on very gentle slopes or flat terrain. The dominant mode of movement is lateral extension accompanied by shear or tensile fractures.

TYPES OF LANDSLIDES
Toppling failures are distinguished by the forward rotation of a unit or units about some pivotal point, below or low in the unit, under the actions of gravity and forces exerted by adjacent units or by fluids in cracks.

Lateral spreads are distinctive because they usually occur on very gentle slopes or flat terrain. The dominant mode of movement is lateral extension accompanied by shear or tensile fractures.
