In southern Styria, the earth shook on April 7 at 18:52 near Leibnitz (46.78°N, 15.54°E). The earthquake with a magnitude of 1.3 was felt by some people in Heimschuh due to the shallow focal depth of around 2 km; a distinct jolt and rumbling were perceived.

The intensity was 4 degrees (EMS-98).

Innsbruck, Tyrol (47.26°N, 11.41°E) was the epicenter of a magnitude 2.6 earthquake that occurred at 01:35 on 25 April and was reported to the seismological service by around 200 people. With a focal depth of around 9 km, the tremors were felt weakly to clearly in Innsbruck and several places in the surrounding area. Many felt a jolt or trembling, some woke up, some were alarmed. Objects moved and glasses rattled slightly, especially on higher floors. The intensity was rated at 3 to 4 degrees on the EMS-98.

The Austrian Seismological Service would like to thank the population for their perception reports, which were used to determine the intensity of the earthquakes.

Excerpt from the short form of the 12-level European Macroseismic Scale 1998, based on Mercalli-Sieberg.

• Degree 2 Scarcely: The tremor is felt only by a very few individuals at rest and in a specially receptive position indoors.
• Degree 3 Weak: The earthquake is felt indoors by a few. People at rest feel a swaying or light trembling. Hanging objects swing slightly.
• Degree 4 Largely observed: The earthquake is felt indoors by many and felt outdoors only by very few. A few people are awakened, the vibration is moderate, slight trembling of the building or room. Glasses, windows and doors rattle, light furniture shakes visibly.
