直播吧04月21日讯本轮法甲，23岁的格林伍德梅开二度，帮助马赛5-1战胜蒙彼利埃。马赛主场看台上却出现了批评格林伍德的横幅标语。

格林伍德本赛季数据出众，但表现起起伏伏，前段时间他曾被主帅德泽尔比批评并弃用，法媒报道称是因他的比赛态度过于散漫所致。

而在本轮比赛，马赛球迷直接在看台上打出标语写道：“格林伍德、恩里克，动起来！！”呼吁格林伍德和他的队友路易斯-恩里克多加努力。

最终标语似乎起到了作用，首发出场的格林伍德第8分钟点射首开记录，第67分钟又攻入个人本赛季法甲第18球，帮助马赛升至第二。

After the Institute of Care-life, a Chengdu-based disaster reduction laboratory, mistakenly issued a 7.7-magnitude alert for a 4.7-magnitude earthquake, the Sichuan earthquake agency on Monday accused the institute of using the name of the official earthquake early warning network without authorization, saying its authorization to use the network had already been terminated last month.
A 4.7-magnitude earthquake struck Yibin at 8:26 am on Monday, according to the China Earthquake Networks Center. However, the Institute of Care-life issued a 7.7-magnitude earthquake alert just five seconds after the quake struck, causing panic among many users.
The institute used the name of the "China Earthquake Early Warning Network" (an early warning system under the China Earthquake Administration) without authorization to issue a 7.7-magnitude earthquake alert to the public through Honor and Vivo smartphones, as well as Xiaotiancai smartwatches, drawing widespread public attention, said the Sichuan earthquake agency in a statement.
The agency said it had terminated the institute's third-party authorization to access emergency earthquake information services from the China Earthquake Early Warning Network on July 22, 2026.
In response to the false alarm, the Institute of Care-life said that its earthquake early-warning network initially estimated the quake at magnitude 7.7 five seconds after it occurred, before revising the estimate to 6.4 at the sixth second, 3.7 at the seventh second, 4.1 at the eighth second and 3.9 at the 16th second. The estimated magnitude automatically converged to 3.9 by the 17th second after the earthquake, the institute said.
Addressing the significant discrepancy, the Institute of Care-life said that deviations in estimates of an earthquake's magnitude and epicenter are inevitable to some extent, as early-warning information is generated automatically shortly after a quake begins, before the seismic event has ended.
The Institute of Care-life apologized for the inaccurate alert and said it would investigate the cause as soon as possible while improving its technology and services.
