Citizen Seismology Unplugged Stories from the ground - BLOG

SolfataraNews offers a live webcam feed of the Phlegraean Fields, pointing towards the Solfatara Caldera, Pozzuoli, Italy, with real-time data from five seismographs showing the constant plume of smoke from the Pisciarelli furmarole.

We have extracted the seismic wave signal from the earthquake that occurred this morning in Sant Quirze del Vallès.

An M3.0 magnitude earthquake struck Sant Quirze del Vallès, Barcelona, ​​early this morning. It was felt in several towns, including Terrassa and Rubí.

A series of large earthquakes, ranging from M5 to M5.8, have struck Japan, 14 km from Yasugichō.

We have created a very useful tool for real-time seismic monitoring using an interactive 3D map. Today's earthquakes

A magnitude 6.2 earthquake was detected by our Citizen seismic station in Girona, Spain, a 36 km W of Puerto Santa

A magnitude 6.6 earthquake struck Taiwan, Republic of China, today. No tsunami warning was issued.

An earthquake of magnitude 2.0 struck Pozzuoli early this morning, near the Pisciarelli fumarole. This area is being closely monitored due to several recent events.

This morning there was a magnitude 2.9 earthquake in the Bay of Biscay, with its epicenter at sea. It was recorded by our citizen seismic station.

A magnitude 5.7 earthquake struck the Mariana Islands at a depth of 72 km. San Jose Village, Rota region

This magnitude 5.1 earthquake occurred south of Italy and Greece. It is considered a moderate earthquake.

We have extracted the waveform caused by the globally detected M7.6 earthquake in Hokkaido, Japan.

A magnitude 7.6 earthquake has just struck Hokkaido, Japan. A tsunami warning has been issued.

We have extracted the waveform of the earthquake that occurred a few hours ago, which shook the towns of Iruña Oka, Álava, and Vitoria.

Thanks to the GlobalQuake online stream, we were able to capture the magnitude of the earthquake that occurred a few hours ago in Iruña Oka, Álava, reaching several countries in the European Union, including Great Britain, Germany, Portugal, and all of France.

An earthquake of magnitude 4.0 struck Iruña Oka, Álava, in the Basque Country, early this morning. It was also felt in Vitoria.

Dozens of aftershocks are occurring every few minutes following the Alaska M7.0 earthquake. These aftershocks are having an average magnitude greater than M4.0. You can follow it live on the GlobalQuake channel.

A magnitude 7.0 earthquake struck Yakutat, Alaska. No tsunami warning was issued. This earthquake coincided with a magnitude 4.8 quake in Greece. Several minor aftershocks followed.

This morning there was an earthquake in Fuengirola, Málaga, near the Strait of Gibraltar, with a magnitude of M4.9. The advisor to the Board of the Interior activates the pre-emergency phase of the Seismic Risk Plan. Emergency calls were received by 112 from municipalities in the provinces of Málaga, Seville, and Córdoba. No damage reported

This guide is designed to help staff and their families prepare for and respond to natural disasters (such as earthquakes) or emergencies requiring evacuation. The guide is also relevant for the Phlegraean Fields area, which is particularly important given recent events (especially the recent earthquakes and the ongoing ground uplift of approximately 2.5 cm per month).

On November 23, 2025, at approximately 08:55:02 UTC, a massive eruption occurred at the Erta Ale (Hayli Gubbi) volcano in Ethiopia, located in the remote Danakil Depression on the Afar Fault. The ash plume, reaching a height of about 15 km and accompanied by significant sulfur dioxide emissions, quickly drifted as far as Yemen and Oman, and even reached Iran, Pakistan, and India.

Campi Flegrei is an area in Pozzuoli, near Naples, just 10 km away. This area is actually a supervolcano, extending even into the sea. In recent months, a continuous and accelerated uplift of the ground (2.5 cm per month) has been detected, along with an increase in the frequency of seismic events, and sustained high ground temperatures exceeding 170°C.

Rain creates small shock waves when it hits the ground, but can these be strong enough to be detected by a Citizen Seismic Station? This article explains it.

It might seem like a silly question, but we won't know until we test it. Is it possible that vibrations could affect the data collected by a Citizen seismic station, causing us to detect tiny vibrations? Let us explain.

We will investigate this using video footage from an ADXL355 accelerometer sensor and seismogram analysis from a geophone calibrated to 4.5 Hz. Watching the video to see how the alarms respond to these events will help you understand how they work.

On October 6, 2025, a magnitude 4.7 earthquake struck central Italy, triggering a massive activation of seismic stations in the surrounding area. One of our citizen radio stations also detected it.

On September 28, 2025, a low-magnitude earthquake occurred near our stations. A perfect local event to document.

On September 25, 2025, an earthquake struck Menegrande, Venezuela, reaching a magnitude of IX on the MMI scale.

A magnitude 3.0 earthquake struck Sicily on September 21, 2025, and was captured by our Citizen Seismic Stations.

This earthquake, although not one of the largest, was detected at our Citizen seismic stations, more than 10,500 km away.

On September 18, 2025, a magnitude 7.8 earthquake struck Kamchatka, the result of expected aftershocks following the recent major 8.8 magnitude earthquake.

Documented arrival of the M7.4 earthquake with tsunami warning from Kamchatka at the citizen seismic station EQ002 in Girona, over 9,000 km away. Full video of the earthquake

In this article, we'll explain whether it's possible to detect thunder with a Citizen seismic station and examine the differences in the waves captured between a geophone calibrated to 4.5Hz, a mid-range ADXL355 MEMS accelerometer, and a low-cost GY-521/MPU-6050 MEMS gyroscope accelerometer.
