Background:

Volcán Popocatépetl, whose name is the Aztec word for smoking mountain, towers to 5426 m 70 km SE of Mexico City to form North America’s 2nd-highest volcano.  The glacier-clad stratovolcano contains a steep-walled, 250-450 m deep crater.  The generally symmetrical volcano is modified by the sharp-peaked Ventorrillo on the NW, a remnant of an earlier volcano. 
At least three previous major cones were destroyed by gravitational failure during the Pleistocene, producing massive debris-avalanche deposits covering broad areas south of the volcano.  The modern volcano was constructed to the south of the late-Pleistocene to Holocene El Fraile cone.  Three major plinian eruptions, the most recent of which took place about 800 AD, have occurred from Popocatépetl since the mid Holocene, accompanied by pyroclastic flows and voluminous lahars that swept basins below the volcano.  Frequent historical eruptions, first recorded in Aztec codices, have occurred since precolumbian

DENTON, Texas – Preliminary Flood Insurance Rate Maps (FIRMs) are available for review by residents and business owners in the cities of Bruceville-Eddy, Golinda, Lott, Marlin and Rosebud and the unincorporated areas of Falls County, Texas.

Property owners are encouraged to review the latest information to learn about local flood risks and potential future flood insurance requirements. Community residents can identify any concerns or questions about the information provided and participate in the appeal and comment periods for the maps.

This is Falls County’s first complete set of digital FIRMs. These maps serve multiple purposes, including defining Special Flood Hazard Areas (SFHAs). SFHAs are areas at high risk for flooding. Community leaders can use these maps to make informed decisions about building standards and development that will make the community more resilient and lessen the impacts of a flooding event.

FEMA stresses that flooding can and does happen outside of the most vulnerable areas.

Review the preliminary flood maps by visiting the local floodplain administrator (FPA). A FEMA Map Specialist can help identify community FPAs. Specialists are available by telephone at 877-FEMA-MAP (877-336-2627) or by email at [email protected].

The preliminary maps may also be viewed online:

CHICAGO – Preliminary flood risk information and updated Flood Insurance Rate Maps (FIRMs) are available for review by residents and business owners in Richland County within the Kickapoo River Watershed. Property owners are encouraged to review the latest information to learn about local flood risks and potential future flood insurance requirements. Community stakeholders can identify any concerns or questions about the information provided and participate in the 90-day appeal and comment period.

The 90-day appeal period will begin on or around September 18, 2025. The preliminary maps and changes from current maps may be viewed online at the FEMA Flood Map Changes Viewer: http://msc.fema.gov/fmcv

The updated maps were produced in coordination with local, state, and FEMA officials. Significant community review of the maps has already taken place, but before the maps become final, community stakeholders can identify any concerns or questions about the information provided and submit appeals or comments. Contact your local floodplain administrator to do so. 

Appeals must include technical information, such as hydraulic or hydrologic data, to support the claim. Appeals cannot be based on the effects of proposed projects or projects started after the study is in progress. If property owners see incorrect information that does not change the flood hazard information, such as a missing or misspelled road name in the Special Flood Hazard Area or an incorrect corporate boundary, they can
