A magnitude 3.4 earthquake with an epicenter southwest of Bombarral

An earthquake of magnitude 3.4 on the Richter scale, the epicenter was 8 kilometers southwest of Bombarral, on the borders of the areas of Leiria and Lisbon, and 14 kilometers deep, recorded at 01:26 this Tuesday within the stations of. Mainland Seismic Network, introduced the Portuguese Institute of the Sea and Atmosphere (IPMA).

An earthquake of magnitude 3.4 on the Richter scale, the epicenter was 8 kilometers southwest of Bombarral, on the borders of the areas of Leiria and Lisbon, and 14 kilometers deep, recorded at 01:26 this Tuesday within the stations of. Mainland Seismic Network, introduced the Portuguese Institute of the Sea and Atmosphere (IPMA).

This earthquake, in line with the knowledge obtainable up to now, “didn’t trigger harm to folks or property” and was felt with a excessive depth IV (on the modified Mercalli scale) within the cities of Caldas da Rainha, Bombarral, Lourinhã and Torres Vedras.

It was even heard to a lesser extent within the cities of Óbidos, Peniche, Cadaval, Alenquer, Arruda dos Vinhos, Mafra, Vila Franca de Xira, Sintra, Lisbon and Cascais.

In Caldas da Rainha, in line with stories from JORNAL DAS CALDAS, the earthquake was felt for nearly 10 seconds, inflicting the homes to shake.

The IV scale equates to perceived average depth. As outlined by IPMA, “it’s regular for suspended objects to rotate. Vibration is much like that attributable to the motion of heavy autos or the sensation of a heavy ball hitting a wall. Parked vehicles rotate. Windows, doorways and dishes shake. Glass and dishes rattle or rattle. In the higher half of this diploma partitions and picket buildings crack “.

Below this worth, depth III is known as weak and on this case an earthquake “is heard in the home. Hanging objects shake. The vibration is much like that attributable to heavy autos passing by. It is feasible to estimate the time but it surely can’t be acknowledged as an earthquake”.

The depth varies on a scale from I to X and extra, with vibrations that may be felt from insensitivity to extremes, because the harm can happen from non-existent to harmful or nearly full.

According to the Richter scale, earthquakes are categorized in line with their magnitude as small (lower than 2.0), very small (2.0-2.9), small (3.0-3.9), small (4 0-4.9), small (5.0-5.9). , sturdy (6.0-6.9), massive (7.0-7.9), vital (8.0-8.9)), variable (9.0-9.9) and excessive (if higher than 10).

Regarding the placement of the epicenter, the IPMA confirms that “the complicated bodily and mathematical processes rely on the dataset, algorithms and fashions of the propagation of seismic waves”. “Different organizations can produce barely completely different outcomes,” he says. Similarly, “the primary beginnings are sometimes modified later, by incorporating extra data”. In reality, the primary IPMA report confirmed that the magnitude was 3.3 on the Richter scale, the epicenter was 10 kilometers southwest of Bombarral and the depth was 13 kilometers.

IPMA launched the primary communication a couple of minutes after the earthquake, including that on the time it had not acquired proof that it had felt, however the urgency of the communication and that it was the final time, with many individuals. sleep, prevented the speedy report of the inhabitants, that’s within the Western area, the area the place the earthquake was noticed essentially the most.

Every day there may be an earthquake in Portugal, which most of the time is just not essential. On December 17, an earthquake with a magnitude of 4.8 was recorded, however the epicenter was at sea, about 260 kilometers west of Porto Moniz (Madeira). On December 14, an earthquake of magnitude 3.0 occurred and was felt with depth III within the city of Coruche (within the province of Santarém), with the epicenter positioned 16 kilometers to the southwest. On August 14, an earthquake with a magnitude of 4.5 was recorded, the epicenter was round 120 kilometers southwest of Faro and was felt with a magnitude III/IV within the cities of Faro and Lagoa (within the Algarve). In all circumstances, no private or property harm was recorded.

However, the worth recorded early on Tuesday is the best within the area in recent times. On February 12, 2021, a magnitude 3.6 earthquake occurred northwest of Rio Maior.

In 2022, the largest earthquake was one measuring 2.5 and with an epicenter about 6 kilometers northeast of Lourinhã, on August 27, it was felt with a magnitude III within the cities of Bombarral and Lourinhã, and one other measuring 1.9 and with an epicenter about 7. kilometers southwest of Lourinhã, felt with nice depth II within the cities of Lourinhã and Torres Vedras, on October 13.
