Thirty days of Earth.

In the last month the planet logged 689 earthquakes at magnitude 4.5 or greater — the largest a 7.7 — while NASA's event trackers followed 1,300 natural events from wildfires to floods to severe storms. This report puts all of it on one map, at true coordinates, with a clock you can drag — every mark traceable to its official record. And because the window rolls, so do these numbers: every figure on this page is computed from the records at render time.

THE MAP

One planet, one month, one picture.

Drag the clock and watch the month happen: shocks bloom in red along the plate boundaries — the Pacific ring assembles itself out of coordinates — while amber wildfire clusters track the dry season and cyan floods follow the monsoon belt. Nothing here is drawn by hand; the geography emerges from the records.

A1The living map — 30 days of shocks and storms at true coordinates
WHAT YOU ARE LOOKING AT An equirectangular world map (Natural Earth coastlines). Red circles are earthquakes — size is magnitude, and the deep ones (>70 km) render hollow with a red rim per the hollow-mark law. Colored marks are NASA-tracked events: amber wildfires, cyan floods, violet severe storms, gray ice. A quake carrying a tsunami flag would wear a cyan ring — and the honest finding of this window is that not one of them does, the largest included; the layer reports its zero rather than hiding. The clock beneath plays the month; category chips isolate a layer. Tap or hover anything for its record.

THE PULSE

The month as a heartbeat.

The map shows where; these show when and how hard. Every shock against the clock, the energy budget of the month — owned to an absurd degree by a single event — and the planet in cross-section, where deep quakes trace slabs of ocean floor diving into the mantle.

B1The seismic heartbeat — every shock against the clock
WHAT YOU ARE LOOKING AT Each mark is one earthquake: left to right is the day it struck; height and size are its magnitude, and color is its depth class — the same cyan/violet/coral language as the section below. Flip the scale to ENERGY and the same month redraws honestly: the murmur collapses to the floor and the giant owns the frame, because that is what a log scale hides.
sourceUSGS FDSN · times UTC methodno smoothing, no sampling — every M4.5+ event in the window drawn; the count above is computed live
B2The energy budget — who owns the month
WHAT YOU ARE LOOKING AT Magnitude is logarithmic, so energy concentrates violently: bars are seismic energy released per day (each whole magnitude step ≈ 32× the energy) and the climbing line is the cumulative share of the month's total. The amber bar is the day of the M7.7 — most of the month's energy in one event, with hundreds of smaller shocks barely registering beside it.
sourceUSGS magnitudes methodenergy ∝ 10^(1.5·M); shares are within-window, not absolute joules
B3The planet in section — depth is tectonic structure
WHAT YOU ARE LOOKING AT Every shock by latitude (left–right) and depth (top–down, to 700 km). Shallow quakes carpet the crust in cyan; violet marks reach intermediate depth; coral marks are the deep events — and they cluster where oceanic plates dive, the Tonga–Fiji slab plunging as a column near 20°S. Depth isn't noise; it's the planet's plumbing, visible.

B4The aftershock tail — the Flores arc after the giant
WHAT YOU ARE LOOKING AT M4.5+ events per day within 350 km of the M7.7 epicenter, the mainshock marked. Before it: near silence. After it: a burst that decays day by day — the classic aftershock tail, visible in one month of records. The next edition watches whether the tail keeps decaying or the arc stays hot.

HOTSPOTS

Zoom in, then compare.

A world map hides as much as it shows. Three hotspot windows — Japan, the Kamchatka–Kuril arc, and Alaska–Aleutians — each zoomed to its own frame with every recorded event inside it, then set against the rest of the world: what share of the month's shocks and of its energy each strip of coastline carried. The shares are whatever the window serves — measured from the ledger, never assumed.

C4The comparison — three hotspots against the world
WHAT YOU ARE LOOKING AT For each hotspot: its share of the month's M4.5+ events (solid bar) and its share of the month's seismic energy (bright bar). A region can be busy but weak, or quiet but violent — the two bars disagreeing IS the finding.

SHOCKS

The eight that mattered.

Magnitude is a log scale — a 7.7 releases roughly thirty times the energy of a 6.7. The month's eight largest, each with its place, depth and instant, straight from the USGS record.

D1The eight that mattered — drawn at true energy scale
WHAT YOU ARE LOOKING AT Each circle's area is the shock's seismic energy (∝ 10^(1.5·M), within this set) — the log scale drawn honestly: the M7.7 IS the month, and a 6.2 beside it is a dot. Numbered pins on the locator map place each shock; tap or hover any circle, pin, or line for the full USGS record.

METHOD

How this was made, and its limits.

The data is official, the pipeline is ours, and every figure on this page is computed from the records at render time. The diagram below is the whole method; the cards under it are its limits — stated, not buried.

E1The pipeline — from official record to this page
methodno map tiles, no third-party trackers · missing records render as gaps, never guesses
Fires are a count, not an area
EONET tracks incidents — the fire figure is tracked fires, not burned acreage or severity.
Below M4.5, coverage is uneven
The regional layer shows REPORTED seismicity — US networks report densely, much of the world reaches the catalog only via NEIC. Above M4.5 the catalog is globally complete: that is this report's analytical floor.
The clock is UTC
Local evening peaks appear shifted; every timestamp is the record's own.
Depth classes are a convention
Shallow / intermediate / deep at 70 km and 300 km — the seismological standard, applied unmodified.
No damage, no cause, no forecast
This is a map of official records. It cannot say what anything cost, hurt, or predicts — and it does not pretend to.
What the next edition watches: whether the Ende aftershock cluster decays along the expected curve or keeps the Flores arc hot; whether the tsunami layer's zero survives another window; the wildfire count as the northern fire season turns; and the rolling window itself — as the M7.7 ages out of the trailing 30 days, the whole energy budget of this page will hand itself to a new owner. That is what a living report is for.
FINDINGS

Five things this month of Earth shows.

1One event owns the month. The M7.7 near Ende, Indonesia released — of the entire window's seismic energy by itself — hundreds of smaller shocks barely register beside it. Magnitude is a log scale, and the energy budget exhibit makes that violence visible. → the energy budget, B2
2What the famous arcs actually carried. Japan, the Kamchatka–Kuril arc, and the Alaska–Aleutians carried — of the month's M4.5+ events yet only — of its energy — because this window's giant struck the Flores arc instead. Busy is not violent, and the hotspot compare draws exactly that disagreement. → hotspots, C4
3Depth is structure, not noise. 27 shocks struck deeper than 300 km, and they are not scattered — they stack into the Tonga–Fiji column where the Pacific floor dives into the mantle. A month of records is enough to see the planet's plumbing. → the section, B3
4The tsunami layer's finding is a zero, and it says so. 0 of 689 quakes this window carry the USGS tsunami flag — the 7.7 included. The layer stays on the map reporting its zero, because absence stated is data and absence hidden is a lie of omission. → the map, A1
5What NASA watches most is fire. 1,222 of 1,300 tracked natural events are wildfires — a count of tracked incidents, not burned area, and the method says so — with floods riding the monsoon belt a distant second. → the map layers, A1
