We analyze short cadence K2 light curve of the TRAPPIST-1 system. Fourier analysis of the data suggests $P_\mathrm{rot}=3.295\pm0.003$ days. The light curve shows several flares, of which we analyzed 42 events, these have integrated flare energies of $1.26\times10^{30}-1.24\times10^{33}$ ergs. Approximately 12% of the flares were complex, multi-peaked eruptions. The flaring and the possible rotational modulation shows no obvious correlation. The flaring activity of TRAPPIST-1 probably continuously alters the atmospheres of the orbiting exoplanets, making these less favorable for hosting life.

    TRAPPIST-1 flares follow a single power law N(≥E_TESS) ∝ E_TESS^{-0.753} from 10^{29} to 10^{33} erg after sensitivity corrections and bandpass conversion.

    TRAPPIST-1 flares obey a single power law N(≥E) ∝ E^{-0.753} from 10^29 to 10^33 erg in TESS energy after sensitivity corrections.
