Why a routine beats random checking

Natural disaster monitoring is most effective when it follows a consistent routine rather than reactive browsing. Random checking leads to either missing important events because you were not looking at the right time, or spending excessive time scrolling through noise without a clear focus. A structured routine solves both problems by establishing a regular cadence with specific checkpoints.

The goal of a daily monitoring routine is simple: spend a focused 10–15 minutes each day to answer one question — what changed across the planet that I should know about? Everything else is follow-up investigation that happens only when the daily scan reveals something worth pursuing.

Step 1: Morning globe scan with PlanetSentry

Start each day by opening PlanetSentry and doing a quick globe scan. Look at the event counters at the top of the dashboard — have the numbers changed significantly from yesterday? Are there new event clusters in regions you monitor? Spin the globe slowly and look for marker concentrations that were not there before.

This takes about two minutes and gives you a global overview. If nothing jumps out, you have confirmed a quiet day. If you see new clusters, unusual concentrations, or high-severity markers, you now know where to focus the rest of your check.

Step 2: Category and region filtering

After the global scan, filter by the categories most relevant to your work. A journalist covering climate might focus on wildfires and extreme weather. A seismologist would zoom into earthquake clusters. An emergency management researcher might look at GDACS alert levels for disasters above the orange threshold.

PlanetSentry's category filters let you isolate specific event types. Combine this with the time range selector to compare today's events against the past week or month. New events that did not exist yesterday deserve the most attention. Long-running events that have grown or changed status are the second priority.

  • Filter by category to focus on your area of expertise or interest
  • Use the time range selector to identify new events since your last check
  • Note long-running events that have changed status, location, or severity
  • Check GDACS overlay for any new orange or red humanitarian alerts

Step 3: Verify and document

For any event that caught your attention, click through to the detail panel and read the source attribution, timestamp, and geometry. Then verify with the authoritative source: follow the USGS link for earthquakes, check the NASA EONET record for wildfires, or read the NOAA advisory for tropical systems. This verification step prevents you from acting on stale or preliminary data.

Keep a running log — even a simple text file — noting the date, event, source, and why it mattered. Over time, this log becomes a personal monitoring archive that helps you identify regional patterns, seasonal trends, and recurring hazard zones. It also creates a documentation trail if you publish or report on any of these events.

Step 4: Imagery comparison for context

When an event warrants deeper investigation, switch to relevant imagery layers on PlanetSentry. For wildfires, check the fire composite and aerosol layers. For storms, look at water vapor and precipitation overlays. For floods, examine the natural color imagery for visible surface water changes.

Use the compare feature to hold the current scene against an earlier date. This before-and-after view reveals how much a fire has spread, whether a river has breached its banks, or how a storm system has evolved. Document what you see — these comparative observations are the foundation of good situational analysis, whether for journalism, research, or personal awareness.
