Where an Uncrewed Aircraft System Could Help After Earthquakes and Extreme Rainfall

Method: facts, proposals, and inferences are different

This study uses documented disaster conditions as scenario inputs. It does not use those events as evidence that ARES would have worked. Each proposed role remains an engineering inference until the aircraft, payload, operating procedure, legal approval, trained team, and field performance have been validated together.

The analysis deliberately avoids casualty figures. It focuses on infrastructure disruption, access constraints, environmental hazards, and coordination needs supported by named sources. Communities affected by disasters are not marketing examples; they are people whose safety, privacy, and authority must shape any data-collection plan.

Case study: 6 February Türkiye–Syria earthquakes

USGS documents a magnitude 7.8 earthquake near the Türkiye–Syria border on 6 February 2023, followed by a magnitude 7.5 event about nine hours later. UNDP later described widespread building destruction, displacement, and disrupted essential services in southern Türkiye. United Nations reporting for northwest Syria documented damaged health facilities and constrained hospital capacity. These conditions illustrate how roads, communications, electrical infrastructure, hospitals, airports, residential buildings, and coordination networks can be affected at the same time.

A fixed-wing observation system could potentially survey broad districts, identify visible road blockages, compare post-event imagery with prior maps, and flag access routes for review before ground movement. Repeated, georeferenced mapping might help planners track debris clearance and changes in temporary access. The output would remain a planning layer, not a structural safety determination.

An airborne relay could extend line of sight between separated teams when terrestrial infrastructure is damaged, but it would require compatible radios, spectrum authority, coverage modeling, encryption and privacy decisions, trained operators, and measured link performance. ARES has none of that field evidence today.

A thermal payload might identify heat sources under suitable conditions, but heat is not proof of a living person. Sun-warmed materials, fires, machinery, animals, insulation, dust, rain, smoke, depth, and viewing angle can confuse interpretation. Any thermal indication would require confirmation by trained ground teams.

• Potential observation: blocked roads, isolated communities, damaged corridors, temporary camps, queues, and visible supply-route constraints.
• Potential mapping: post-event orthomosaics, change detection, visible collapse indicators, and debris distribution.
• Limits: dust, smoke, rain, darkness, thermal ambiguity, battery capacity, restricted airspace, launch-site access, and collision risk.
• Coordination: helicopters, crewed rescue aircraft, multiple drones, temporary flight restrictions, spectrum congestion, identification, and a single command authority.

A UAV can improve situational awareness, but it cannot replace trained urban search-and-rescue teams, structural engineers, medical responders, rescue dogs, heavy equipment, or local knowledge.

Case study: June 2026 Venezuela earthquakes

USGS reports that magnitude 7.2 and 7.5 earthquakes occurred in northern Venezuela west of Caracas on 24 June 2026. Its preliminary remote assessment identified landslide impacts, possible road obstruction, potentially isolated communities, and areas where cloud cover or unavailable imagery prevented assessment. UNICEF issued an earthquake-response situation report the following day, confirming a developing humanitarian context without making ARES part of that response.

For a scenario in northern Venezuela, potential ARES roles include surveying landslide corridors from a safe standoff, locating visible road blockage, and helping analysts compare alternative access routes. Coastal observation might cover piers, shoreline roads, port approaches, and settlements that are difficult to reach from inland routes. Repeated mapping could document aftershocks, secondary slope movement, road clearance, and recovery progress.

A communications relay might connect separated field teams across a line-of-sight gap, but mountainous terrain can shadow radios and GNSS-assisted pointing cannot remove terrain blockage. Tropical weather, cloud, wind, and rain can reduce camera performance or ground the aircraft. Landslide zones may continue moving, and a safe launch or recovery site may not exist.

• Potential infrastructure observation: bridges, utility corridors, transmission lines, public buildings, ports, and inaccessible mountain roads.
• Required coordination: local aviation approval, emergency command authority, spectrum management, and ground-team confirmation.
• External dependencies: satellite or terrestrial communications may still be required beyond the aircraft link.
• No claim: autonomous survivor detection is not an established ARES capability.

Case study: July 2026 torrential rains and flooding in China

Chinese government emergency reporting in July 2026 described rain-triggered floods, landslides, house damage, river and reservoir concerns, urban waterlogging, disrupted roads and public services, large-scale evacuations, and emergency responses across multiple regions. The environment was dynamic: rainfall, typhoons, flash-flood warnings, geological hazards, and changing river conditions affected wide areas at different times.

After conditions become safe enough to fly, an observation aircraft might map flood extent, identify visibly inundated roads and neighborhoods, and repeat routes to document change. River-channel imagery could help analysts notice debris accumulation, overflow indicators, or erosion for professional review, but it cannot replace gauges, hydrological models, dam instrumentation, or on-site engineering inspection.

Road and slope observation could support evacuation-route assessment by showing dry corridors, bridge approaches, and visible secondary movement. Any recommendation would remain with local authorities. An airborne relay or low-power position-broadcasting experiment would require separate authorization and validated coverage; an illumination payload would add energy, mass, glare, safety, and privacy issues and is not a current ARES capability.

• Potential post-rain documentation: agricultural damage, road erosion, housing damage, and interrupted utility corridors.
• Critical limits: heavy rain, water ingress, low visibility, gusts, fog, spray, cloud, RF degradation, GNSS uncertainty, and unsafe recovery surfaces.
• Operational principle: a delayed flight can be safer and more informative than an aircraft launched into the peak hazard.

In the most severe part of a storm, the correct operational decision may be not to fly.

Objective capability matrix

Survivor localization is limited and highly uncertain without validated sensors, trained operators, environmental context, and confirmation by ground teams.

Supply delivery is not a current primary ARES capability unless payload, release safety, flight performance, and authorization are separately validated.

What ARES Cannot Solve

Responsible engineering includes knowing when not to deploy a system. ARES cannot safely fly in every weather condition, see through all collapsed structures, confirm life from imagery alone, replace rescue teams, guarantee continuous communications, or operate without legal and airspace coordination.

• It cannot provide unlimited endurance or guaranteed immunity to electromagnetic interference.
• It cannot remove debris, deliver medical treatment, or make humanitarian decisions independently.
• It cannot substitute for local knowledge or turn incomplete sensor data into certainty.
• It cannot make unsafe airspace, an unsuitable launch site, or severe weather acceptable through software alone.

A narrower engineering question

ARES ReFlight is not presented as a completed answer to disasters. It is an evolving engineering effort built around a narrower question: can a carefully designed fixed-wing uncrewed system improve situational awareness and communications when conventional infrastructure is damaged?

The answer cannot come from branding, simulation, or confidence alone. It must come from testing, cooperation with responders, regulatory approval, documented limitations, and evidence gathered under realistic conditions.

Until then, the project will continue to publish both its ambitions and its uncertainties.
