This entry examines the clause of Sahih al-Bukhari 1036 that earthquakes will become very frequent before the Hour, and tests it against the instrumental seismic record. The record, as read by the major geological surveys, does not show a natural increase, and this entry says so plainly.
The source text
“The Hour (Last Day) will not be established until (religious) knowledge will be taken away..., earthquakes will be very frequent, time will pass quickly, afflictions will appear, murders will increase and money will overflow amongst you.”
Sahih al-Bukhari 1036 · Grading: sahih (Bukhari-Muslim by definition)
What was understood in the seventh century
The narration is sahih. The Prophet Muhammad (peace be upon him) lists frequent earthquakes among a cluster of signs preceding the Hour — alongside the loss of knowledge, quickened time, afflictions, killing, and overflowing wealth — without attaching any timescale.
Earthquakes were well known in seventh-century Arabia and the Near East and were universally read as portents, so the motif itself was familiar to the first audience; what the hadith adds is the claim of increasing frequency at some unspecified future point. The Near East's seismic belt runs through Anatolia and the Levant, and major shocks punctuated late-antique chronicles, so the first hearers had a concrete referent.
The fulfillment record
The U.S. Geological Survey and the British Geological Survey both state that there is no evidence naturally occurring earthquake activity has increased. The number of recorded earthquakes has risen dramatically, but seismologists attribute this to the growth of seismograph networks — from about 350 stations in 1931 to many thousands today — and to more people living in seismic zones, not to more earthquakes occurring. Human-induced seismicity, for example from wastewater injection, has genuinely increased in specific regions since the 2000s, but that is a localized, anthropogenic effect.
As a documented physical correspondence, therefore, the claim is not established: what has been observed is better detection and greater exposure, not a rise in earthquakes themselves. The foretold increase remains unobserved, and this sign should be classed as not demonstrated — possibly still awaited — rather than fulfilled. Believers who cite rising disaster reports are largely citing reporting effects. This entry exists on the site precisely to model that discipline: where the best physical evidence contradicts a popular fulfillment claim, the claim is set aside.
Considerations and counterpoints
Beyond the seismological point, skeptics note that earthquakes-as-omens is a stock motif of ancient eschatologies — it appears in the Gospels' Olivet discourse — so its presence in a signs-of-the-Hour list is expected literary content rather than privileged information. Defenders reply that the sign may refer to a period still ahead, which, critics answer, makes the claim unfalsifiable for now. The case here is therefore weak on present evidence, and the entry does not soften that conclusion.
Credibility rating: Tier 3 · Contested — The hadith is authentic, but the empirical claim of increased seismicity is contradicted by the instrumental record as interpreted by geological surveys, so no fulfilled correspondence can honestly be asserted.
