今天8时26分四川宜宾市长宁县发生4.7级地震，针对网友收到7.7级预警信息，成都高新减灾研究所发布说明：8月24日8:26四川宜宾长宁发生4.7级地震，成都高新减灾研究所的大陆地震预警网对该地震的预警震级序列依次为7.7级（震后第5秒）、6.4级（震后第6秒）、3.7级（震后第7秒）、4.1级（震后第8秒）、3.9级（震后第16秒）。震级在地震发生的第17秒自动收敛到3.9级。    Dhaka, Oct 19 (UNI) ‘M/V Trans Samudera’ departed Chattogram Port Wednesday carrying Indian transit container that was transported from its Northeastern state Meghalaya via the territory of Bangladesh.
This movement of cargo is part of the trial runs being undertaken for the operationalization of the Agreement to use Chattogram and Mongla Ports for the transit of goods to and from India which was signed between Indian and Bangladesh in 2018.
The trial run is being undertaken by Tata Steel and CJ Darcl Logistics Ltd. on the route Dawki–Tamabil–Chattogram.
There are eight approved routes for transit of goods under the Agreement, namely, Chattogram/Mongla Port to Agartala via Akhaura, Chattogram/Mongla Port to Dawki via Tamabil, Chattogram/Mongla Port to Sutarkandi via Sheola, Chattogram/Mongla Port to Srimantapur via Bibirbazar and vice versa on all four routes.
During Bangladesh Prime Minister Sheikh Hasina's visit to India in 2019, a SOP was signed to operationalize the Agreement.
The first trial movement under this agreement on the route Chattogram-Akhaura-Agartala was successfully conducted in July 2020 wherein four containers, two each of TMT steel and pulses, were delivered at ICP Agartala from Kolkata through Chattogram.
The transit/transshipment of goods under this agreement will reduce both cost and time for transport of goods to Northeastern States of India. It will also create economic gains for the Bangladesh logistics and services industry (Insurance, transport and Finance industry etc.) as only Bangladesh trucks will be used for transshipment.
This trial run marks the completion of all trial runs on all approved routes under this Agreement.
Trial runs on the routes Mongla–Tamabil–Dawki, Mongla–Bibirbazar–Srimantapur and Chattogram–Sheola–Sutarkandi have also taken place.
Following this completion of trial runs, necessary permanent standing order/notification would now be issued by the Government of Bangladesh for the operationalization and regular movement of goods under this Agreement. This is a step forward in realizing the commitment reiterated at the level of the two the Prime Ministers, Narendra Modi and Hasina, during her visit to India in September 2022.
UNI MAZ ING。以下为预警震级序列图：对此次较大的偏差，成都高新减灾研究所表示，地震预警的震级、震中位置有一定偏差是必然的，因为预警系统是在地震刚刚发生时自动发出的信息，此时地震还没有结束。
