Main parameters

Magnitude and intensity

Two numbers often confused, with the values of this earthquake and of the Observatory’s catalogue.

1Magnitude: the size of the earthquake

The magnitude (ML 3.0) measures the size of the earthquake at its source, from the amplitude of the waves recorded by seismographs: a single value for the whole earthquake. Since 1985, 96 % of the 3,122 earthquakes with a magnitude in the Observatory’s catalogue have a smaller one.

1Focus and epicentre

An earthquake starts at depth, at the focus (or hypocentre): here 10 km below the surface. The point on the surface right above it is the epicentre (49.576° N, 8.457° E), the one the map shows.

Values from the page and the Observatory’s catalogue (tectonic earthquakes since 1985).

Macroseismic inquiry

How the macroseismic inquiry works

Using the answers to the “Did you feel an earthquake?” questionnaire for this earthquake.

1Testimonies

29 answers to the online questionnaire were received for this earthquake, from 16 municipalities. Each dot is a municipality, larger when it has more answers; the farthest, LANGENFELD (RHEINLAND), is 201 km from the epicentre, outside the frame.

Intensities derived from the answers to the online questionnaire “Did you feel an earthquake?”, grouped by municipality (former municipalities included). The map and the chart give the intensity of each municipality.

Notes and method

Intensity of a municipality or a cell (CII, Community Internet Intensity) is computed as follows:

  • I if no answer reports that the earthquake was felt;
  • F earthquake felt, but fewer than 3 answers kept per municipality or cell;
  • II–IX computed from 3 answer(s) kept: CII = 3.40 ln(CWS) − 4.38 (Wald et al., 1999), applied to the weighted sum (CWS) of the mean indexes of the answers; at least II if felt, at most IX.

Answers kept (USGS method, as applied by the ROB): reliability of 80 or more, given on the ground floor up to the 4th floor (or unknown floor), without those more than two standard deviations from the mean. The “felt” index is weighted by the answer to “Did others nearby feel it?”.

Distribution by intensity: macroseismic intensity (MI) recorded for each answer.

Cells: 5 or 10 km squares of the Belgian Lambert 72 grid, each answer placed at its geocoded address or at the point it placed on the map, otherwise at the centre of its municipality. The positions of the answers are published only rounded to about 1 km, in “Arrival of the answers”. Grid cell method: Van Noten et al. (2017), Solid Earth 8, 453–477, doi:10.5194/se-8-453-2017.

Arrival of the answers: time each answer of reliability 80 or more was sent, duplicates removed; position rounded to 0.01° (about 1 km), geocoded or otherwise at the centre of the municipality, where several answers may therefore pile up. Answers without a usable sending time or position, not shown: 4.

Answers without a known municipality, left out of the map and the chart: 5.

Notes and method

Tectonic and induced earthquakes from the Observatory’s catalogue, suspected ones included; quarry blasts, explosions and other events are not counted. Epicentral distances on the WGS84 ellipsoid.

Municipality: 2025 municipal boundaries (Statbel), applied to every earthquake, including those before the merger of municipalities. For an epicentre outside Belgium, only the circular area is given. Each earthquake’s name is the catalogue’s: it may refer to a place near the epicentre.

Magnitude: the one given on each earthquake’s page (ML preferably, otherwise MW or MS); magnitudes of different types are compared as they are.

The epicentres of historical earthquakes are only known to within a few kilometres, sometimes more: whether they fall in the area is indicative. Small earthquakes have only been recorded as the station network grew: the area’s older earthquakes are mostly the largest ones, and recent activity looks more frequent.

When the area holds fewer than 5 other earthquakes, the nearest ones beyond 10 km are listed too, up to 100 km. Sequences (aftershocks, swarms) take a single row there, that of their largest earthquake: an earthquake joins a sequence if it occurs at most 7 days after the previous one and within 5 km of the first.

Did you feel an earthquake?The inquiry takes just a few minutes. Every report helps seismologists assess the effects of the earthquake.
