Earthquakes
In the Civil Protection Department's seismic classification of municipalities, updated in May 2025, the Comune di Massa is in zone 3, where strong earthquakes are less likely than in zones 1 and 2.
Floods and landslides
The Comune's page on ISPRA's IdroGEO platform, with the indicators of the ISPRA 2024 report, estimates 37.5% of residents in areas flooded under the medium-hazard scenario and 8.8% in high or very high landslide-hazard areas. Before choosing a home it is worth checking the area on the same platform's map.
Air and water
According to ARPAT's 2025 Yearbook, the MS-Marina vecchia station exceeded the daily PM10 threshold of 50 µg/m³ on a single day in both 2023 and 2024 (35 exceedances a year are allowed), and nitrogen dioxide stayed below the annual limit. The Frigido-Secco water body is in good ecological status and not good chemical status for 2022–2024. In 2024 the municipality's 12 bathing areas, over about 13 km of coast, gave 74 compliant samples out of 76.
Contaminated sites
The same yearbook lists 239 sites under remediation procedures in the Comune di Massa, covering about 2,465 hectares, more than in Carrara; ARPAT warns that the data may not be fully complete or up to date.
